Doitsu Kohaku, Doitsu Sanke, Doitsu Showa and Doitsu Yamato Nishiki just to name a few. Doitsu Koi went through centuries of selective breeding and most of the time rated highest rating fish can receive.

In the late 1800’s German Koi were imported in Japan to improve the supply of edible fish, since it did not have scales with a bulkier body shape which means more meat to eat. Also, another purpose of importation is to cross-breed the German carp with the indigenous carp.

Two German scientists, selected 40 fry of the best quality available in their country, then transported all of it to Japan. Only 7 carp survived the trip as it is during the Japanese-Russo War. 6 leather carp and 1 mirror carp turned out to be the genetic backbone of Doitsu as we know today.

To compare with Japanese carp, the body shape of Doitsu carp was more rounded and shorter. They also have a better growth rate than local carp. However, they mature early and do not reach the same old age as Japanese carp. They even show less resistance towards diseases. Fortunately, as observed by scientists; the offspring of Doitsu carp shows very hybrid vigor as a result when it is used in breeding with other carp. Doitsu Koi is sometimes called as “Mirror-Scale Koi” because along its back, you will find a mirror-scale dorsal line. If not available at Koi’s back, you can find the mirror-scale lateral line on its side.

There are several scalations to be found on Doitsu carp. Doitsu Koi with scales only found on the back are called Kawigoi or mirror carp. Those Koi without scales at all are known as Kawas Goi or leather carp. Additionally, a Koi with scales on the back as well as the lateral line are called as Kagami goi or striped carp.

Most of the genetic make up of Koi varieties today, do have Doitsugoi blood. Doitsu Hariwake, Doitsu Kohaku, Doitsu Sanke, Doitsu Showa and Doitsu Yamato Nishiki just to name a few. Truly, Doitsu Koi went through centuries of selective breeding and most of the time rated highest rating fish can receive.

how to identify male and female koi fish

excerpt posted from

Koi fish are a great addition to any garden pond or aquarium. But whether you just brought your koi fish home or its spawning season fish friends, determining the sex of your koi fish can prove difficult for new owners. This is especially true if the koi are still young. However, determining koi fish gender is important for the health of your koi. If you can determine the gender of your koi, you can more easily watch for gender-specific sickness and disease in the koi’s life. Read ahead to learn more about koi genders!

Male and female koi differ slightly in shape and size.

Male and female koi differ slightly in shape and size.


Sexing, or identifying the sex, can be difficult if the koi is under a foot long. However, with older koi you can easily identify the gender by comparing size. Generally, male koi are slimmer and smaller than their female counterparts. Female koi have a fuller body and broader shoulders. However, at a young age, male koi are typically larger than female. Male koi may also have larger pectoral fins than females. These fins are more pointed than round female fins.

You can also identify a koi’s gender by examining the vent area on the underside of the fish. A male koi will have a line from head to tail. A female koi will have the same line, but will also have another crossing in a “T” shape. A female’s vent will also be more round and more pink than a male’s.


Observe your koi during feeding to see if they skirt away or fight for the food.

Observe your koi during feeding to see if they skirt away or fight for the food.

If you carefully feel your koi’s pelvic bones, females will have a soft abdomen in between the bones for holding fish eggs. In male koi, however, these bones are fused. Again, these methods are difficult when koi are young.

Also take note of your koi fish’s eating habits. Females tend to be more aggressive during feedings, staying near the surface and continually eating, while male koi swim around more throughout the session.

During spawning season, male koi will develop some tiny white spots on the sides of their face. These are called tubercles and feel rough to the touch, like sandpaper. Females do not develop tubercles.


Placing male and female koi together in a koi pond will not guarantee spawning. Koi prefer shallow areas around a pond to spawn. Many ponds have steep sides and are at a recommended five feet depth.

Female koi produce eggs each year if nutritional and environmental needs are met. These eggs are released once the water warms up enough (68˚F). The Japanese believe the full moon generates spawning.


Females release koi eggs during spawning season, usually during early summer.

electrofishing philippines

I thought electrofishing is just okay until I found out that there is a law prohibiting this act. I really never thought that this is prohibited since ever since I grew up. I always saw my fellow country men doing it. Here is a video proving it.

And here is the law


Section 1. Except for research, educational and scientific purposes, authorized by the Secretary of Agriculture and Natural Resources, it shall be unlawful for any person to engage in electro-fishing in any of the fresh-water areas of the Philippines.

Sec. 2. As used in this Act, the term “electro-fishing” means that method of catching fish in which electricity generated by dry cell storage batteries, electric generators or other sources of electric power, is utilized to stupefy, disable or kill fish and other aquatic animals; the term “fresh-water areas” shall include all rivers, lakes, swamps marshes, dams irrigation canals and other bodies of fresh-water in the Philippines; and the term “person” shall include natural and artificial persons.

Sec. 3. The penalty of imprisonment ranging from six months to one year and a fine of five hundred to one thousand pesos shall be imposed on any person guilty of violating Section one of this Act, and, in addition, all the apparatus and paraphernalia including the boat used in the electro-fishing shall be confiscated and forfeited in favor of the Government.

Koi fish are a common symbol in both Chinese culture and feng shui, depicted on artwork, clothing, tattoos and even with live fish used in landscape design. Learn more about what these ornamental carp mean to those embracing this ancient symbol.

The Koi Fish Legend

There are many ancient legends involving the koi fish. The oldest of the legends is the story of when Chinese philosopher Confucius was born a son in 533 B.C., King Shoko of Ro presented to him a magoy, a black carp, as a gift. According to this legend, all modern day koi, and their bright colors, are from the magoy given to Confucius by the king.

The legend says the Chinese then raised the koi in their rice patty fields to be used for food, especially during the long winter months, and not for pets. The Chinese then passed on their knowledge of raising koi to the Japanese. Raising koi in ponds began in Niigata, Japan during one particularly harsh winter.

Niigata Koi

During this very harsh winter, Japanese farmers in Niigata could not fish and could not sustain any crops. As a result, the farmers began building ponds in which to raise koi in order to feed their families. During this time, many farmers began noticing different color mutations on the skin of the newly bred koi. So they carefully chose the most beautifully colored fish and bred them in separate ponds to keep as family pets.Koi continue to be bred as pets and enjoyed for their wonderful coloring. Today, there are over 100 different color types of koi fish.

What Do Koi Fish Symbolize?

Learning it’s history helps to answer the question, “What do koi fish symbolize?”. By knowing koi’s long history, you can more easily understand why people revere this beautiful fish so deeply.

General Symbolism

feng shui koi fish color symbol and meaning

Many of the attributes of the koi symbolize several lessons and even trials individuals often encounter in life. The koi fish has a powerful and energetic life force, demonstrated by its ability to swim against currents and even travel upstream. Some of the characteristics associated with the koi include:

  • Good fortune
  • Success
  • Prosperity
  • Longevity
  • Courage
  • Ambition
  • Perseverance


Many of the above described symbolic meanings of koi fish stem from the Chinese legend of the Dragon Gate in which a koi fish swam upstream, through waterfalls and other obstacles to reach the top of the mountain. At the top of the mountain was the “Dragon Gate”. The legend says that when the koi finally reached the top, it became a dragon, one of the most auspicious creatures in Chinese culture.

Coloring Symbolism

The fish’s coloring also has something to do with its symbolism. Certain colors represent certain aspects or outcomes in life.

  • Kohaku – This koi has a white body with red spots and symbolizes success in your career.
  • Kumonryu – There are two main variations of this koi. One variation is a koi with a white body and black spots and the other is an all black body. This Kumonryu koi symbolizes life changes and transformations.
  • Ogon – This solid, silver colored koi symbolically represents success in business and wealth.
  • Kuchibeni – This white and red patterned koi is often referred to as the “lipstick” fish, because the red coloring around its mouth makes it appear as though the fish is wearing lipstick. Kuchibeni koi represents love and long lasting relationships.
  • Yamabuki – The Yamabuki koi is gold in coloring and symbolizes riches and wealth.

Koi as a Traditional Chinese Food Source

No symbol in the Chinese culture has a singular meaning behind its status, especially when it comes to feng shui symbols. The koi has a varied background of how it was elevated to the symbol status of being auspicious. One of the things to remember is that in less modern times, the koi was a vital part of the Chinese diet. The farmers raised the fish in their rice fields in a perfect ecosystem. The fish provided fertilizer for the rice crops while the aquatic life found in the rice fields sustained the koi.This is a good example of the balance in life that the koi represents. When times became hard, often during the winter months, the rice farmers would survive by eating the highly nutritious koi. Some feng shui experts believe this history of the koi and its importance in sustaining the Chinese people first as a fertilizing source for the rice crop and then as a direct food source was the beginning of the koi becoming a symbol of prosperity.

Yin Yang and the Koi Symbol

In feng shui, the koi is tied to the yin yang symbol. In fact, the black and white tear drops of the yin yang symbol are said to be representations of two koi, one male and one female. The eye of each teardrop is symbolic of the constant watchful eye of the koi. This pairing of fish is often seen outside the context of the yin yang symbol as well. For example, a pair of koi is often used as a good luck symbol for a happy marriage.

Harmony and Happiness

The koi is synonymous with harmony and happiness. The two yin and yang koi complete each other and create a perfect balance of the negative and positive energies of chi energy, which is the life-force of all things on earth.

Koi in Feng Shui

feng shui koi fish color symbol and meaning

Koi can be represented in interior design with artwork such as paintings, photographs or sculpture. Its placement is said to attract auspicious abundance and prosperity into your home and life and some opt to have multiple representations of this fish.

Koi can be included in a home either in a pond or very large aquarium. If you are considering raising a koi on your own, be sure that you always usher auspicious energy your way by keeping the water fastidiously clean and well-filtered and by ensuring they have ample space to swim and grow.

By keeping your koi healthy, you can expect them to live anywhere between 50 and 75 years. It’s no surprise that these colorful fish symbolize longevity, since some say that some koi have lived for nearly 200 years.

How Can You Construct a Koi Pond?

A simple detail on how to setup and construct a koi pond

How Can You Construct a Koi Pond?. Koi ponds are made so that it might consider the most appropriate living demand for koi fishes. You might find them in the yard behind house in many cases; whatever, they can also place in front yards if there is a lot of available space there. In the process of constructing koi ponds, the water & oxygen are the greatest consideration. This will really resolute by the size of the fishes.

Landscape gardening plays an important role in Koi ponds. There is efficient amount of koi pond layouts out there for you to select from. While you might already have some pre-imagine plan on how it might be designed, you have to make certain that it set the whole water garden objects completely in a faultless way.

Some of the general points of how to construct a koi pond based on the type of landscape that you have are give below.

1. Particular Place.

During you might be incitement to put your Koi pond at the far limit of your yard, it is very significant to remember that you must have to uninterrupted monitor its demand. You will have to make sure the fishes daily. As well as, you also have to see if the plants are still flourishing or if the fish have already sensual on them.

The position of the ponds should be suitable for the changing weather condition. It would not be exposed during the hot and cold seasons. You could always add some more defense for the pond in case you aren’t confident about how it would prosper in that location. Knowing your yard would help you find out where you could place your Koi pond.

2. Area

Trying to find out the size of koi pond isn’t like figuring out any customary ponds. This is because of the fishes would get bigger overtime. You would get be astonishing at how much they could grow especially if you are captivating adequate care of them. The length of the pond is significant & would of course depend on the size of your yard, direction in your yard & overhanging trees, which would lower down the amount of available space.

3. Plan of revenue

You required having a budget set apart for explaining a pond for your koi. Take note that some of the fishes & other things for decorations for it don’t come cheap.

You may want to limit your expenses and make sure you are not overspending for it. Other not-so-important parts and materials can be added later on when you have supplementary resources. Remember, room wasn’t built in a day, and neither should your pond.

Koi fish transforming into a dragon

This is the story of little blue koi dragon had the strength and courage to climb a certain waterfall and koi fish transforming into a dragon

Koi fish transforming into a dragon. A long time ago, in the distant past, the water of the
blue river that flowed from the sky, and the golden river
that flowed from the land were separated by the legendary
Dragon’s Gate.
The golden river, so-called because of the golden colour
of its water, was the last place where the inhabitants of
the sea could swim freely, after the gods that walked on
the earth had destroyed their massive home, believing
themselves to be the owners of everything they laid their
eyes on.
Amongst all the inhabitants of their water, the Koi family
were the most beautiful of all, gleaming in the
sunlight like brilliant stars. The black one was father
Koi, the red one was mother Koi, and their little son was
a remarkable deep blue colour.
What the little Koi fish wanted more than anything was
to reach the waters of the blue river after hearing from
his father how there was a time where there were no
barriers between one place and the other. The bravest
fish, the dragon fish, flew across the sky like pearls
lighting up the darkness. The entrance was upstream,
through the Dragon’s Gate to the Great Waterfall of the
blue river. Every fish that got that far sprouted golden
wings and so became a dragon fish.
The young Koi, determined to find the Great Waterfall,
began to swim upstream against the current. The other
fish felt discouraged and thought it would be easier to
swim with the current and didn’t trouble themselves to
find out what was beyond the waterfall because the
gods set traps to trick them.
Although the current was very strong, the little Koi
made a huge effort, flapping his fins as much as he possibly
could. Gradually, he made progress and moved up
the river. The loud splashing noise attracted the attention
of the gods. Angry because a small fish dared disobey
them, they gave orders to summon the river mouth
monster, who swallowed whole everything that swam
across its path. They didn’t bargain on the fact that the
Koi, being as small as he was, would easily swim
through the monster’s holey skin.

The Koi kept on swimming upstream until, suddenly,
the water turned dark and dirty. He couldn’t see anything
and started to feel terrible. The gods were boasting
they had been victorious against the efforts of the
little fish when, suddenly, from the shore, the God of the
Air appeared and, taking pity on the fish, gave orders
for a whirlwind to take away all the dirt and to clear the
way so the fish could continue.
The Koi kept going. He could feel in his fins he was
getting closer. He carried on swimming. But then
something odd happened: there was less water surrounding
him. Suddenly he bumped into a stone wall that
reached up almost as far as the sky. What was he to do
now? The Dragon’s Gate was on the other side of the wall.
It occurred to him that his only chance was to jump as
high as he could. So that’s what he did, without giving up,
even though all the time he could hear the gods laughing
at him. Time and again he hurled his body into the air,
only to fall back down into the water.
He was so tired that the wall appeared even higher. But
not for a moment did he feel like giving up. Moved by
his courage, the God of Water, who had been watching
the little fish, wanted to give him a hand, since the gods
had halted his progress and acted so disdainfully
towards the river. When the Koi had summoned all his
strength for one last jump, the God of the Waters called
out to the waves and the fish’s jump raised him up to
the summit, allowing him to cross to the other side of
the Great Waterfall of the blue river.
So it was that, because he never give up, the Koi was
able to jump over to the other side of the Dragon’s
Gate where he disappeared into the fog and emerged
as a beautiful dragon fish. At night, the little fish can
be seen splashing happily in the waters of the great
blue river.
Ever since that day, any fish that, like the little Koi, has
the strength, courage and perseverance to go against
the current and overcome difficulties, is rewarded by
being transformed into a beautiful Dragon Fish.

how to safety transport koi fish

Excerpt from

Transporting koi safely from one pond to another or to a koi show

It is possible for koi to be transported from the dealer to the home pond, from one pond to another if a koi-keeper should change address, or be transported to and from koi shows without discomfort or risking harm to them provided it is done correctly. There are two main methods; they may be transported individually in plastic bags or in a purpose made transport tank which will usually be designed for transporting several koi at once.

With either method, it is important that the koi should not be stressed either during the netting process, during bagging and transport or when they are released. Stress is a commonly used word in koi-keeping circles but what does it mean?

The purpose and benefits of the stress response
In the very short term, a physical/physiological stress response in animals, including fish, has been an evolutionary advantage. When faced with an environmental condition or a situation that might affect its health or its safety, the automatic response is to release into the bloodstream what are commonly called “fight or flight” hormones. The full physiological effects are too complex to describe in detail here but hormones such as adrenaline and cortisol prepare an animal to fight off the aggressor or to get away from the situation as quickly as possible. Functions such as the heart rate, blood pressure and respiration increase. Blood flow is diverted away from bodily functions that can be dispensed with in the short term in order to allow maximum blood flow to the muscles and parts of the body that are most important to the fight or flight response. After fighting off the aggressor or getting away from the situation as appropriate, the levels of the stress hormones subside. The heart rate and respiration return to normal and such functions as were put on hold for a few minutes can resume.

Since koi were not designed to fight, their preferred response to a fight or flight situation is to swim quickly away to safety. If it is possible for them to do this then the stress response would be a good reaction. The stress hormones which will have allowed the koi to get away from danger can quickly subside with no long term ill effects on it. But what will happen if a koi cannot get away from a situation where it perceives itself as under threat?

The potential harmful effects of continued stress
The stress response evolved to give fish (and other animals) maximum advantage in a fight or flight situation but if a fish cannot escape from the stressful stimulus, the release of stress hormones will not stop after a few minutes, they will continue to be released. The fight or flight response that evolved to provide a short term advantage now begins to work to the detriment of the fish. The heart rate and respiration were not designed to work at elevated levels for longer than a few minutes at a time. Nor were the digestion, immune system and osmoregulatory system intended to be shut down for extended periods. A fish that is stressed for extended periods by its environment or other stressful situations can become physically harmed by processes that originally evolved in order to allow it to swim quickly away from danger. Alternatively, its depressed immune system might allow the koi to fall victim to a disease or pathogen that it might have successfully resisted if its immune system had been working to its full efficiency. This explains why fish sometimes fall prey to diseases such as ichthyophthirius multifiliis (white spot) after being subjected to a stressful journey or situation. This parasite is common in the aquatic environment and is normally successfully resisted by healthy fish but it can take advantage and infect a fish that has an impaired immune system.

The importance of water quality in avoiding stress or harm when moving koi
The fear in a fish of potential danger is not the only stressor (stress stimulus or situation) that can trigger the stress response; this response can also be caused by poor water quality. Just as a potentially dangerous situation would normally cause a koi in a lake to swim rapidly to a safer place, poor water quality would also invoke the same response. A koi in a travel bag or transport tank, in which water quality is poor, will become doubly stressed; firstly by the physical effects of the poor water quality and secondly by the fact that it is unable to swim away to somewhere where the water quality is better.

Preparation when koi are about to be moved is a key factor in ensuring good water quality during transport. Koi are ammonotelic which means that they eat and metabolise protein which results in the waste product, nitrogen, being excreted in the form of ammonia. For this reason, unless the journey is likely to be short, it is a good idea not to feed koi for about five days before they will be transported. This will allow any protein they have eaten to be fully metabolised along with any stored amino acids from that protein. It is the breakdown of protein into amino acids and the further breakdown of those acids that produces ammonia as a waste product so, after this period, although the excretion of ammonia will not cease entirely, it will be very much reduced. Decreasing the amount of ammonia that can build up in a travel bag or transport tank, not only reduces the risk of harm due to ammonia burns, to the gills or fins in particular, but when a high ammonia level reduces water quality in a travel bag or transport tank, a fish will be stressed by that poor water quality.

A second reason to not feed fish for five days before they are moved in order to reduce their ammonia excretions is due to the fact that the ammonia level inside a fish cannot be lower that the ammonia level in its surrounding water. If koi are fed normally before being moved and, as a result, ammonia were allowed to build up in the water in a travel bag or tank, the ammonia level that will build up inside a fish in that water due to it being unable to dump ammonia can cause it to become stressed. In extreme cases, the elevated ammonia level inside the fish may even prove fatal.

A third reason not to feed fish prior to them being moved is because a great deal of oxygen is required in order to digest and metabolise food. Koi that are being regularly fed will take more oxygen from the water than those that haven’t been fed for a few days.

The higher oxygen demand of regularly fed koi in a koi pond is unimportant. As respiration removes oxygen and replaces it with dissolved carbon dioxide, the air stones in the pond will replace that oxygen and help remove the carbon dioxide by a process known as gassing off. When koi are being moved in a bag, the oxygen available to them is obviously limited to whatever is in the bag at the time it is sealed and so, if feeding is suspended prior to them being moved, the oxygen in the water in the bag will not be depleted so quickly. When koi are moved in a transport tank, it is usual for there to be an air pump that can run from the vehicle’s battery and so, as long as this air supply is sufficient, it is arguable that if the koi are only being moved from one pond to another, the higher oxygen demand of fish that have been fed normally will not be important. This is true but since normally fed fish will cause more ammonia pollution in addition to the higher oxygen demand, even koi that are being moved in an aerated transport tank should still not be fed for five days prior to the journey.

It should be noted that where koi are being transported in order to take them to a koi show, not feeding them for the five days prior to the show is also a requirement under the Show Rules and Guidelines of the UK Koi Policy Unit (UKKPU) which were published in November 2010 and which are soon expected to define show protocol for all UK koi shows.

11.4.1 The Koi should not be fed by the Koi Keeper for 5 days prior to travelling to the Koi Show. There is sufficient natural food in the pond to sustain them. This precaution will help to minimise ammonia in the transport bags and significantly reduce the need for water changes due to raised ammonia levels in your Show Vat.
There have always been recommendations regarding feeding koi before koi shows and this rule was written in its present form so as to be compliant with appropriate animal welfare legislation. It has since been adopted in its current wording in the BKKS show rules as published in March 2011.

Oxygen in travel bags
The amount of dissolved oxygen that water can hold is very small when compared with the amount of oxygen in the air above it and since the dissolved oxygen will rapidly start to deplete anyway, it makes sense to have the maximum amount of air in the bag to replace that oxygen as quickly as it is being used even though this will mean having less water. It is necessary to have the gills completely covered when the bag is lying in its normal horizontal transport position but the water need not be any deeper than that. The water in the bag doesn’t need be deep enough to cover the dorsal fin. Fish in a bag need air, not water depth.

Methods for inflating the bag will be described later but if the water just covers the gills when the bag is horizontal and the rest of the bag is filled with air, there will be enough oxygen in that air for one fish for an hour. If the journey and floating time necessary to equalise temperatures is likely to exceed one hour, the space above the water should be filled with oxygen as described in “Inflating the bag” below.

Although there will be more than sufficient dissolved oxygen already in the water and in the air space above for journeys in excess of an hour without the risk of suffocation this should be considered the maximum travelling time for koi without adding oxygen to the bag. If oxygen is added, the higher level of dissolved oxygen that this will produce will go a long way towards ameliorating any harmful effects from the build up of ammonia in the water.

The water in a transport tank or travel bag should, as far as is possible, be prevented from becoming excessively warm during the journey. This will be easier with a tank than it is with a bag because the greater volume of water will change temperature more slowly but both should be shaded from the sun. If the temperature of the water is allowed to rise, the level of dissolved oxygen will fall and it is even possible that, regardless of dissolved oxygen, the water temperature in a travel bag in a car parked in the sun whilst the driver stops for lunch could rise beyond the survivable limit for koi. Journeys should be kept as short as is possible, especially in hot weather.

For journeys significantly longer than an hour in hot weather, there will be an advantage if the transport water is cooled slightly by external ice packs. This will slow the koi’s metabolic rate which will reduce the amount of ammonia it excretes and its oxygen consumption. Decreasing the oxygen consumption in turn will also reduce the build up of carbon dioxide in the water in travel bags. When carbon dioxide is dissolved in water it forms a weak acid, (carbonic acid), which lowers the pH. Koi can acclimatise to a range of pH but they can be stressed if the change happens too quickly. Although it is true that the lower pH would help to protect the koi from the effects of ammonia in the water, [link to explanation to be inserted when available], if the water is cooled slightly, both the build up of ammonia and the rapid decrease in pH will be reduced which is advantageous to the koi. The use of ice packs should not be over zealous. The water shouldn’t be abruptly cooled by more than 2°C or 3°C below that of the water from which the koi is being transferred.

Signs of stress in a fish
Since the evolutionary purpose of the stress response in fish has been to provide it with the best advantage possible to escape from a potentially dangerous situation by physiological changes such as increasing the heart rate, blood pressure and respiration rate, these will be the most noticeable effects that will indicate that a fish is stressed. The normal slow, even and rhythmic gill movements will become more rapid and they will open more widely than usual. The increased blood pressure and blood flow through the capillaries (very fine blood vessels) in the skin will cause a general reddening of the skin and cause the capillaries to become visible as fine thread like red streaks. This is particularly noticeable on white skin. The increased blood pressure in the fine gill capillaries may also cause them to burst resulting in bleeding from the gills.

De-stressing additives to the transport water
Anecdotally, salt, small doses of various fish anaesthetics or proprietary products are not uncommon when transporting fish. Koi dealers and some koi-keepers who are experienced in transporting koi may achieve good results by adding salt or a light anaesthetic or other additive to transport water. If experience shows that the fish are less stressed during transport by these methods, there is no reason why they should be discouraged. But for the lesser experienced hobbyist, since individual methods and conditions of transport are too varied, no recommendation regarding additives to transport water is given here other than to say that if an additive is used, it should be one that is specifically recommended by a manufacturer for this purpose and should be used strictly in accordance with the manufacturers’ instructions.

Netting and bagging
Fish should always be transported in double bags. Strong, clear PVC bags from a koi dealer are ideal, flimsy food bags or similar bags are not. To put one bag inside another, put a small amount of water in what will be the inner bag and drop it into the outer bag, its weight will allow it to fully drop inside. Both bags should be rolled down together by about ¼ their length to form a cuff. This cuff will prevent water getting in between the two bags and also act as a floatation collar allowing the bags to be floated in the water in order to be ready at hand when required.

There are many different methods to net and bag koi. The experienced koi-keeper may have a preferred method which quickly and efficiently transfers the koi into a bag without causing it to be stressed in which case there is no reason to change. For the less experienced, possibly the least stressful way is to use a bowl and a second person to assist.

how to feed your koi

It is better to decide a certain place for feeding your koi They will gather when they hear your footsteps. A flat feeder is good for the bait which sinks to the bootom. It is necessary for a pond with a Y shaped bottom. You can enjoy feeding koi more with floating koi food on the surface. As koi gets tame easily, you may enjoy hand feeding them. then you will love them more.


Amount of koi food to feedAmount of koi food to feed

Koi should not over eat. Thirty minutes of feeding them is enough. The amount of koi food depends on the structure of a pond, the way to control it, the number of koi and their size. Their appetite is influenced by their health, especially by parasites Argulus and lernea by weather and climate In the summer they have a strong appetite but in the winter they hibernate and do not eat much food is necessary no breed koi large in a short time as koi cannot eat much at a time they must be fed often.






time-to-feed-koiTimme for feeding koi
As koi do not have organs equivalent to stomachs, they cannot eat much at a time. Therefore they must be fed often, a small amount at a time, in order to grow large. However, in this case the number of koi should be small and water must be well-controlled. Most beginners keep too many koi, but are not good at controlling theri ponds. If they feed their koi much, they may kill them owning to oxygen shortage. Generally it is safe to feed koi only twice a day, about ten oçlock in the morning and one oclock in the afternoon.








Kinds of koi food

different kinds of koi food
Koi are polyphagous and eat everything that we eat, bread, fish meat, beef, chicken, shellfish, etc. koi food are grouped into the natural food, the artificial food, the vegetable food and the animal food. Koi’s color is carotin pigment. Rutine for yellow and Astaxanthin for red are especially important. The fish food which contains them is highly prized for coloring. For example, chlorella containing Rutine and spirulina containing Diastaxanthin are valued. Green vegetables such as cabbage, watermelon and green pepper which contain Rutine are preferable used as natural food. A live shrimps and crabs which contain Astaxanthin are loved as animal food. Earthworms, clam and other shellfish are often used pupae and cooked wheat have been generally used from old times. Some koi keepers make paste bait mixing various materials. Recently pellets and floating koi food which contain coloring matter are manufactured and sold. There are crumble and powdered koi food for baby and small koi fish.As therer are various fish food, it is desirable to mix some of them on feeding koi instead of using only one kind. The ratio of the vegetable koi food to the live koi food is 6 to 4. In the winter the digestible vegetable koi food is suitable.

A concrete pond 30 centimetres deep is sufficient for the fry. It is necessary to grow Daphnia in the pond before the fry are put in it. The day when the fry begins to eat daphnia and the day when Daphnia begins to grow are to be the same. Preparation for growing Daphnia should begin two weeks before the expected day of spawning.

The preparation is as follows.
Dry the pond under the sun and sprinkle lime to disinfect the pond. After two days fill the pond with water put dried fowl droppings wrapped with a straw mat under water. Fix it with a heavy stone in the corner of the pond. Infusoria, vegetable plankton such as chlorella and other bacteria will breed first in ten days Daphnia will begin to grow. If not, put some Daphnia starter culture they will increase rapidly.
When fowl droppings are put in the water it becomes brownish red, but it gradually gets transparent. Then Daphnia increases. It is the time to put the fry in the pond.
10 kilogrammes of fowl droppings per 7square meter is sufficient. If they are put too much, Daphnia does not begin growing soon, but they continue to increase long. If they are too little, Daphnia begins to grow shortly but disappear soon.
Recently yeast is used for growing Daphnia instead of fowl droppings. 3 to 4 kilogrammes of yeast per 1 is sufficient. In this case, Daphnia comes out in two days but do not increase for a long time. So yeast should be supplied little by little. Yeast. can be added to fowl droppings, when Daphnia do not increase much.
After being hatched. the fry begins to eat vegetable plankton, Infusoria and fresh Daphnia to grow up. When they get larger, they eat imagoes of Daphnia. After a month of feeding them Daphnia, it is all right to begin artificial food.
In case Daphnia never grows, artificial feed, fine boiled egg yolk, is useful. Dried Daphnia, powdered shrimps, milk or dry milk powder and powdered feeds too. It is necessary to take care not to decompose water on giving them to koi

The pond for spawning can be used again, but a vinylene tank or a vinyl coated pond 1.5 to 2 meters in diameter will be convenient.

The water temperature should be the same as that of the pond for spawning. If it is more than five degrees Centigrade lower, the eggs will die. If it is more than five degrees centigrade higher, they will possibly be decomposed.
The are hatched in 4 to 4 days When the water temperature is high, hatching occurs shortly. When it is low it takes a long time. In tropical countries such as the Philippines, it will hatch in just 2 days because of warmer temperature. In two or three days after hatching the fry being swimming already. Daphnia is given to them for two weeks, then they are put in an ordinary pond for small koi.

How to cull good koi
culling by basket

How to cull good koi Culling is the most important of all the words of breeding koi. Generally, it is thought that if many koi are bred, some of them must be excellent koi. It is not true. Mass production does not breed a good koi. It is weaker than other koi and its growth is slow. Bad koi are strong and eat good but weak koi. Most bad koi grow faster than their siblings because they develop their growth first and most of these kois are single colored kois these kois are called “tobi”. Tobi  devours weak, small, beautiful kois,  Therefore, it is necessary to cull good koi from poor koi  called tobi as soon as possible.
Culling is done, when fry is one to three months old. Fry are grouped according to the size and the kind, too. Such baskets as the photograph shows are useful for culling.
During one to three months, three or four times of culling are done. The first culling is performed two weeks after hatching for the Showa, fifty days for the Ogon, about sixty days for the Kohaku and the Taisho-Sanke. Deformed, plain red, white and black koi are thrown. only ten to twenty percent of all are left. The second culling is done for the pattern and the quality. For these reasons it is important to breed koi with the same pattern so that you will not be having hard time culling your koi.
Culling good koi is very difficult. So your discerning eye affects the result of breeding koi greatly. It would need practise and applications and study to perfect the art of culling and producing quality good koi.

Peer Into the Future for Show-Winning Koi!

1601koi002aOne of the most enjoyable aspects of owning a koi pond is picking out your new pond family members. A trip to your local koi dealer is exciting, and you generally have a plan in mind before you walk through the gates. For instance, how many koi do you need? What size? Which colors or classifications are you hoping to find, and how much are you willing to spend? Whether you are shopping to add beauty to your pond or shopping for a future show koi, the reality soon takes hold when you look into the tanks and cannot decide. Are you making the right decision?!“What will this koi look like in a few years? Should I buy large or small? Who can help me?”

Gambling with Tosai

When we look at koi, we have to understand that what we see when we are buying Tosai (one-year-old koi) is not what we may see in the future. This is especially true when we are buying baby koi in the typical 3-to-5-inch and 6-to-8-inch ranges. That perfect Sanke at 6 to 8 inches today may be a show-winner in three years. Or, it could be bleached out or blackened and lose all color and value. Will the colors run or splotch? Will the pattern improve with the growth of the koi? Will the black take over? Will the red disappear? These are questions that we all ask, novice and professional, because it is not a perfect science. And that is what makes “growing out” koi exciting. It is a fun and dynamic hobby.

No matter how experienced, you have no guarantees in choosing baby koi. This fact is at the heart of the reality that most koi show winners are purchased as larger fish already. With grown koi, you can see what you are getting. But breeders and many hobbyists alike enjoy the challenge and the game of raising the koi from babies and gambling with a little luck.

Picking the Greats

So how do you pick future greats when they are merely 4 to 6 inches now? How do you guess what the fish will look like in three years? Although it is not a science, there are definite traits we look for in baby koi that increase the likelihood that our new little addition will add great beauty to our pond for years to come.

We are going to discuss three of those traits: Body and Quality; the Red and the Black; and finally, Pattern.

Body and Quality


1601koi001First and foremost, we have to buy the healthiest fish, as this is key in growth potential. Make sure the fish is swimming normally, socializing with the other koi in the tank, has no apparent fin or body flaws and has head and tail potential. When we look at the head, we are looking for a broad head and good separation between the eyes, signifying the likelihood that the fish will grow larger. At the tail, we are looking for a wider tail joint so that when the koi is larger, the thickness will “show” more powerful conformation.

“Skin quality” means high gloss and shine as well as purity of color. Ultimately, how detailed the breeders are in their culling and their use of trusted bloodlines really makes a difference. This is why you should buy from sources that have a tradition for great koi. Certain farms are known for high gloss, pure whites, deep reds, Ginrin or reticulation patterns from head to tail, et cetera.

The Black and the Red

Inspect the black, buy the red. When choosing reds (Hi) and blacks (Sumi), seeing the fish in the future is critical to your selection. Red is the baseline “must-have” to consider the koi. However, red is delicate in small koi, so you want to look for deep, consistent red from the front to the back of the koi and in large patterns rather than splotches. Consistency from head to tail and side to side is what we want our Hi (red) to become. Of course, we need to see the potential future two-step/three-step/four-step pattern down the dorsal, but it is more than pattern. The red has to stay there, and that is why we are looking at the details of the coloring beyond the pattern.

To best guess where we will keep the red, we look at the edges of coloring. We want the head side of the red patterns to be a little blurred, because we are looking at those red scales under the white scales in front of them. This gets cleaned up when the koi grows. If we do not see this, then the red is likely shallow and the front line of red will change. In the sides and tail end of the color patches, we want to see defined separation between the red and the white rather than a messy mixture. Bold red is the ultimate goal.

Where the Hi is your baseline on the white painter’s canvas, your Sumi (black) is the icing on the cake. Sumi can be equally hard to predict and even more frustrating than red because often times underlying Sumi never develops. So you choose a Showa with great Hi and a potential Sumi pattern that would be “show-worthy,” and then half of the Sumi does not develop and you are left with a poor-quality koi with black only at the tail, or scattered. Or, when the black does rise, it is flat rather than high-quality gloss.


This baby Shiro Utsuri Ginrin and Tosai Inazuma Kohaku have great potential. Both display great body shape; their color is deep, broad, and defined; and their patterns have winning potential.

When we look at the black, we want to see two things. First, we want at least one scale of good Sumi present in the young koi we can judge well (most Sumi is under the top layers of scales in baby koi, so you are looking through red or white scales and unable to determine quality of black).

Second, we want the black to be darker in the center of the scale than on the edge. You can check the center of the scale by carefully bending the fish to spread the scales apart and looking between them to see the color going through to the body of the fish, although this is not very commonly allowed by retailers in order to maintain the safety of the fish. If the outside edge of the scale is darker, be it Sumi or Hi, this is not a stable color and will likely go away. We want to see color that is darkest deep into the scale. This is the color that will develop well. Also, for a truer mark, pay more attention to how good the black on white is and less attention to the black on red.


Pattern is what most buyers see, and it overwhelms the above qualities that are more important. In saying that, though, pattern is ultimately what sets apart the good from the great. One of the critical elements to look for in pattern is how far down the side of the baby koi the pattern falls. As the koi matures, it broadens its body shape, so a baby koi with far-reaching pattern down the sides, below the lateral line, will hold more color pattern as it grows and the pattern “spreads” across the wider body. It is critical that pattern exist from head to tail, but when selecting baby koi you have to know that generally speaking, red is stronger near the head and weaker toward the tail. Also, black starts heavier at the tail and often works its way up the fish with age (in Sanke and Showa primarily).

1601koi005Remember, you are buying koi that have not “filled out” yet. The most common mistake in buying baby koi is buying what you see and not what you don’t see. You need to know what color patterns do with maturity and predict where colors will change. For example, it’s very likely that a great three-step adult Kohaku was the baby Kohaku that had solid red head to tail that looked too plain. But an educated and experienced eye might have seen “stepping” potential in the red that would occur as the fish broadens and the red stretches, allowing white to show through.

It is a gamble buying baby koi, but it can be the most enjoyable and rewarding part of the hobby. Shop reputable suppliers, listen to trusted experts, have them “bowl” several fish for you to compare side by side, and you may raise a Show Champion one day by shopping out of the 5-to-7-inch tank. And that would be an achievement any hobbyist would be proud of!





Another great resources from Mike the Fish

Mike Fish Trying to pick a koi for show while it is a fry is almost impossible since as they grow the pattern and color will change. The best way is to know the parents and what quality koi they come from. I will also add that a koi coming from Japan does not guarantee quality, since most koi sold in Japan have been interbreed and is either second and third fourth quality.

Some will tell you that pattern has very little to do with a Koi when they are judge, This false. You can have two koi of the same quality and the one that has a better pattern and color will win. Now I will say that size if the first thing they do look at.

Now if you are wanting to grow Koi for show, I would suggest that you find one that with a good pattern and then work on making it grow. I would also have more then one i would work with. Koi fry grow at different rates. I have found that the ones that grow at a slower rate can be helped by placing them into a the right environment until they reach about 3 inches.

After a koi reaches about 4 inches. You will have to change what you have been doing keep them growing at a fast rate. It will take a lot of work. You will have to be willing to do a 10 to 20 percent water change daily. You have to keep the water temperature up to about 74 degrees. water changes should be done manually and not by a set up as some use. There is a different between a pond that been set up to do the water change and doing it manually. Doing water change manually removes the hormones koi release in water. Therefore they are not sure how big the pond is, and will allow them to grow faster.

You have to place Koi clay in tank or pond which clouds the water and makes it harder to see them. But Koi clay gives the koi a lot minerals introduced by adding clay vary according to where it was mined. Bentonite clay is particularly rich in calcium. Calcium cannot be synthesised by fish and is vital for strong bones and scale development, it is a catalyst for enzyme action and other metabolic functions but it has other benefits as far as pond water is concerned.

Calcium has what chemists call “a negative electrical charge” which means that as this type of clay settles slowly to the bottom of the pond it will attract positively charged impurities to it. Although calcium molecules don’t actually remove impurities from the pond water, nor can calcium make the impurities vanish, they will be permanently locked together and, as such, they cannot affect the fish. Then, when the clay is filtered out as sediment in the filter bays and flushed away, it takes those pollutants with it. In this way, toxins such as heavy metals, free radicals, and pesticides are removed from the pond.

Growing show quality koi is a lot work and money. When you get a koi it is like plain canvas. It is what the owner does while it is growing to will help it as it grows. But there is no guarantee that the Koi will achieve show quality.

I have many right now that I bought this fall. I will be selling in the spring. Because while they are growing good, their color and pattern is not what i am looking for.

Nishikigoi is a general term for colored koi with markings which are bred for appreciation. Before the second world war it used to be called Colored koi, flowery koi, figured koi or fancy koi, but the authorities did not approve of the words colored or flowery during the war, so it was rename Nishikigoi. The word koi was first used about 2500 years ago in China. It was in 533 B.C. when Confusius son was born and was presented a fish by King Shoko of Ro. The fish was name Koi. The original home of ko was said to be Persia. They were brought to Japan through China and Korea about 1000 years ago. The colored koi, however, were born in Japan. They are work of Japanese art. The Doitsu is a kind of the Nishikigoi which has been bred for food. Its orgin was a black carp. In japan a Nishikigoi and a Doitsu were cross bred and a colored Doitsu was born. The Nishikigoi is called living jewel or National fish. It was Mr. Komei Koshi-hara, the president of Nagoya women’s college, who named the Nishikigoi Living jewel or National fish was first used in a photo album of the first all Nippon Nishkigo Show in 1968. Mr. Hideo Miya of Ojiya was its inventor.

Essential Koi Pond Supplies

Essential Koi Pond Supplies

Essential Koi Pond Supplies

As a new Koi pond owner, you may be overwhelmed with the amount of supplies needed to properly maintain your Koi pond. While the importance of the majority of these items cannot be denied, the feeling of being overwhelmed by the amount needed should be disregarded. Simply knowing the function of each item can help you understand why they are needed.

There are certain items that you need to have on hand at all times. Because you pond is outdoors, emergency situations do occur. Nature is simply unpredictable at times, and you do not want to be caught in a situation where an item is needed, but they is no way to obtain it.

Filters- Having a working filter is essential for removing unwanted pollutants, and maintaining proper water quality. If you do not have a proper filter, water quality issues can occur, which in turn will cause your fish to have health issues.

submersible pumpPump– A pump is essential to the health of your pond. If you water is not moving, there is no way the system can process the water. Moving water can also be from waterfalls, fountains, and other water features, but in no way should completely replace your pump.

Dechlorinator- Tap water contains chemicals that can potentially harm your fish. When adding new water for any reason, you must add Dechlorinator to eliminate these chemicals.

Test Kits– You will need to have ammonia and nitrite test kits on hand at all times. You will need to perform weekly water tests on your water to ensure proper water quality. Emergency tests may also be needed in the event that you notice discrepancies in your Koi behavior or in the water.

Pond Salt and Baking Soda- Pond salt and baking soda are used to regulate kH and Nitrate levels in the event that you find a discrepancy. Pay close attention to the amounts you are suppose to add to your pond, which depends on size and the issues you are currently having.

Bags- You must have the proper bags on hand to transport Koi. Do not attempt to transport your Koi in trash or regular plastic bags, as they are not designed for this, and may cause damage to your Koi. Unless you remembered to keep the bags you brought your koi home in originally, you will have to make a trip to your local pet store. Make sure to get bags sizable enough to hold your Koi.

Rubber Bands- You will need quite a few rubber bands for each bag you buy. Make sure that your rubber bands are good quality, as you do not want the pressure from the water to pop the rubber band in the middle of the transport.

Net- You will need to have a net sizeable enough to compete with your Koi. You will never need the net to pull the Koi out of the water with, but you will need it to lead and direct your Koi into the place you want them. Nets can potentially damage your Koi, especially as the larger they get.

Paint Bucket- A paint bucket is a better option for catching your Koi, as they cannot hurt your Koi like a net can. Make sure that your bucket is sizable enough to hold your Koi.

Koi Staple Food- Like any other pet, Koi need to be fed daily. Talk with your local pet store or Koi dealer when picking foods for your Koi, as different seasons may dictate the type of food you need to be feeding. Koi have even been known to eat out of their owner’s hand, so make sure to get food in which you are able to do this with.

Koi Treats and Snacks- Like other animals, Koi delight in treats, and will respond in a playful manner to them. Specific Koi treats are available at your local pet store. If you do not mind feeding “human” food to your pets, you may even consider feeding your Koi veggies, fruit, and bread.

tetracycline treatment for fish

by Shirlie Sharpe

tetracycline treatment for fish

In ornamental fish, Tetracycline is used to treat a variety of external and internal bacterial infections, including these disorders:

  • Hemorrhagic  Septicemia – bacterial infection of the bloodstream. Characterized by bloody streaks on the body and fins.
  • Cotton mouth disease – bacterial infection that affects the mouth with fungus like growth and erosion of the mouth parts.
    • Fin Rot – Fins and tail become ragged and frayed, in some cases almost completely eroding.
    • Gill Disease – Fish breathe heavily and gills appear bright red.
    • Open Body Sores – Bacterial infection causing open red sores on the body.
    • Body Slime – Slimy patches appear on the body, fish flashes against objects and breath rapidly.
    • Pop-eye – Eyes are hazy and may protrude from head.
    • Cyanobacteria – also used to treat cyanobacteria (blue-green algae).

Generally tetracycline is more effective against aerobic bacteria, particularly gram positive organisms. In infections caused by gram negative bacteria, minocycline is more effective than tetracycline. Tetracycline becomes more potent as it ages, so expiration dates should be carefully adhered to.

Tetracycline will kill nitrifying bacteria, so avoid using it along with other antibiotics to reduce the impact these drugs have on the biologicals. Monitor water chemistry closely for several weeks following treatment with this antibiotic, testing for ammonia and nitrite. Avoid the use of this drug if fish are already suffering from ammonia or nitrite poisoning, or diseases that have already rendered the fish significantly anemic.

High general hardness (GH) will reduce the effectiveness of this drug. Tetracycline it is not effective at all when the water pH is higher than 7.5. Remove any carbon filter media when using this drug, as it will remove the Tetracycline from the water. Tetracyclines can be safely used together with Methylene Blue.

Minocycline is a broader spectrum antibiotic than the other tetracyclines, particularly in treating infections caused by gram negative bacteria. Of the tetracycline family, it is most effective against septicemia.

Area tropical fish store opens with a splash

CIRCLE PINES — A new pet shop is making waves in Circle Pines.

Xeng “Andy” Moua and his wife IaOng, or “Mandee,” recently opened Quality Aquatics Pet Shop. It is the latest phase of Andy’s lifelong hobby with the tropical animals.

“I was probably 10, I was really into fish,” Moua said. “As I got older, I was messing with this fish thing for close to 15 years, keeping it at home.”

Eventually, he opened a store in Columbia Heights with his brother. “We had it up and going less than two years. That was really new to us. I learned a lot from that experience, so now I have a better idea of what direction I should go with the shop,” he said.

“I decided not to open another one again (after closing the store with this brother), but for some reason I couldn’t get it out of me, so here we are,” he said.

The no-frills fish store is located at 9205 Lexington Ave. N. in Circle Pines, in a strip mall that has become popular with new tenants these last few months. Moua and his wife, who now live in Arden Hills, previously lived in Circle Pines, so they knew the area.

“We didn’t really choose this location, it chose us. We came to get our DMV tags around the building, and we saw a vacant sign. I said, ‘Let’s go take a peek at it.’ One thing led to another and we ended up signing the lease the same day,” he laughed.

A recent online fish list for the store includes a Peacocks & Haps section with an alphabetical listing of Aulonocara lwanda to Tramitichromis intermedius. There is a Fossorochromis rostratus (female only), and an assortment of extra large male Nimbochromis venustus.

In addition, the store stocks Tanganyika, mbuna, goldfish, koi and plecos. The crocodile pikehead, black ghost knife and Chinese high-fin shark are all listed under the Oddballs category.

“I work with a lot of distributors. I like to carry a lot of varieties,” Moua said. “My store doesn’t cater to just one specific type of fish. I have community fish, goldfish, koi, African cichlids, discus. I try to carry every type of fish I can. You never know what a customer is going to want.”

Some customers may want a Leichardti arowana, listed at $239 and change. One of his most popular fish is the silver arowana, just under $22. “That’s a ranchu, he’s being a goofball,” Moua points to a knobby round gray fish dancing around as if he knows he has an audience.

Moua sells feeder fish that can go home with the buyer’s new freshwater fish. Aquariums and accessories are not yet part of his inventory.

Although Moua’s fish store is new in this neighborhood, word gets around. “I have customers from Wisconsin, Fargo, Iowa — I was surprised. I didn’t expect that deal,” he said smiling.

Moua used to work in auto body repairs. “I wasn’t passionate about it like I thought I would be. I’m more passionate about fish than cars.”

Koi carp robbery: Garden focus staff "disheartened" by episode as advance to follow important fish proceeds

Staff at the garden focus where koi carp worth more than £7,500 were stolen have talked about their pity in the wake of finding the fish had been taken.

Squire’s Garden Center in Badshot Lea close Farnham was the casualty of a fairly abnormal wrongdoing amid a break-in at the middle between 6.30pm on Friday (March 10) and 7.30am on Saturday (March 11).

Ten koi carp in addition to one sturgeon were stolen from an outside show tank, with the hoodlums leaving only one fish swimming all alone in the water.

The wrongdoers likewise exchanged an air circulation block in the water to an abnormal state, implying that a blind of air pockets shaped on the surface of water, disguising the reality the fish had been taken.

Martin Breddy, overseeing executive at the branch, stated: “There was a feeling of stun truly and tremendous dissatisfaction in light of the fact that the staff take awesome care of the fish.

“They turn out to be extremely appended to them. Some of these fish have been here for a few years, genuine example koi.

“There was a great deal of suspicion about how on earth somebody had figured out how to take such enormous fish.”

He proceeded with: “That by itself demonstrated to us that it more likely than not been a significant operation and a really proficient operation to dispose of 11 such huge fish.

“The fish are all very novel. The thing that gatherers like is to have the most surprising examples.

“On the off chance that the fish do turn up anyplace, if individuals are truly careful then quite possibly’s we may discover the offenders however more critically we may recover our fish.”

Dane Pullen, sea-going administrator, said he was exceptionally disturbed in regards to the robbery: “They’ve arranged how to do it,” he said.

“It would take a dreadful parcel of care. Our primary concern is the welfare of the fish since it’s no simple undertaking to get these, to pack them up, to box them.

“For them to come in, plan the expulsion of those sorts of size fish. They plainly realized what they were after and the instruments to do it.

“They’re not simply angle, they are not only an item, they are a piece of the store – it’s a genuine misfortune.”

The 10 stolen koi carp

Security is presently being ventured up at the garden focus. Surrey Police propelled an interest about the robbery on Thursday.

Sergeant Paul Edwards stated: “Each of the koi carp are around a large portion of a meter long, in this way it would have required a sensible measure of investment and conceivably various individuals to take the fish from the show pool.

“I would speak to any individual who was in the territory at the season of the occurrence and saw anything suspicious to approach to officers.”

Anybody with data is made a request to call Surrey Police on 101 citing reference 45170025350 or call Crimestoppers philanthropy namelessly on 0800 555 111.

ILIGAN CITY – What used to be a filthy drainage canal in Purok de Oro in Barangay Poblacion is now a favorite hangout for locals after it was transformed into a koi pond.

Lito Dela Corta and Richard Digamo said that last year, they discovered how their neighbor’s tilapia thrived in the canal despite the polluted water that ran through it.

“They also had a koi carp which grew really big, so we thought it was possible to breed them here,” Dela Corta said.

They cleaned up the canal and gathered almost three hundred sacks of garbage from the drain which they also used to support the embankment.

Besides making the canal much more pleasing, the koi also had an unexpected health benefit to residents nearby.

“We also do not worry about mosquitoes anymore. They eat mosquito larvae,” said Digamo.

Digamo and Dela Corta feed their fish with leftovers from a nearby fast-food restaurant.

The two have also inspired others to replicate their makeshift fish pond.

Koi Stolen from Surrey Store, Have you seen these koi fish?

These ten extra large Koi were stolen from the display pond, along with a sturgeon, at Squire’s Garden Centre in Badshot Lea, near Farnham on Friday, March 10.

Intruders broke in late on Friday evening, and took these very valuable fish, which are worth a total of £7,725. The Koi are all over half a metre in length and had been selected in Israel for their quality by Squire’s Pets and Aquatics Manager, before being imported from Israel to Squire’s in Badshot Lea.

Deputy Chairman Sarah Squire says: “We are all absolutely devastated that this theft has happened, and are very concerned about the welfare of the fish, as they require a large pond or facility with well-filtered oxygenated water. Pet welfare is at the top of our agenda at Squire’s. We urge people to come forward if they have any information.”

If you know anything about this theft, please get in touch with Surrey Police by calling 101 or email: [email protected]

Garden Design and Waterfall company steals the show with impressive display.

Bound Brook, New Jersey (PRWEB) March 04, 2017

New Jersey’s Fitz’s Fish Ponds won big at this year’s New Jersey Flower & Garden Show. Held in the NJ Convention & Expo Center in Edison, New Jersey, this was the 15th annual show for the organization, and Fitz’s first time as a participant. The theme for this year was “Color The World” and focused on unique garden displays developed by garden centers, nurseries, and landscapers inspired by colorful places throughout the world.

The four-day event, held from February 23rd, 2017 through February 26th, 2017, featured almost 200 exhibitors. Many categories were offered, including horticulture, botanical decor, outdoor lighting, and more. Fitz’s Fish Ponds incredible displays were designed by Mike Hall, and highlighted a variety of Fitz’s services, including koi fish ponds, backyard designs, unique waterfall creations, and outdoor lighting structures. Although the event did not begin until Thursday, the Fitz team arrived at the Expo Center that Monday to begin building the display. They worked tirelessly to develop the impressive architecture from the ground up and their hard work clearly paid off.

Not only did onlookers recognize the aesthetic beauty of Fitz’s displays, but the Flower and Garden Show judges did as well! Fitz’s Fish Ponds won not one, not two, but a whopping FIVE first place prizes at the event. Best Landscape Design, Best Use of Structural Elements, Most Creative Water Feature, Most Dramatic Outdoor Lighting, and Best in Show of 2017 are now titles held exclusively by the Fitz Team. Additionally, Fitz also placed second for the People’s Choice award. As passersby ogled at the glittering waterfalls and the lively Koi fish in their ponds, owner Brian Fitzsimmons couldn’t help but beam with pride.

“Huge display, we’ve been here since Monday building it…it’s unbelievable!” said Brian of the show.

In a seemingly busy and crowded arena, Fitz’s ponds and structural display offered not only creativity and excitement, but also serenity. Printed on banners around the exhibit was Fitz’s message, “Making your backyard dreams a reality.” This has been a goal of Brian Fitzsimmons’ since age 13, when he built his first pond in his parents’ backyard while they were away on vacation. These days, Brian is able to bring the feeling of vacation and paradise to backyards across the entire Tri-state area. With both their retail store as well as the many services they offer, Fitz’s Fish Ponds is a full service pond developer and supplier. The 2017 New Jersey Flower & Garden Show was not the only place for visitors to see Fitz’s amazing work. Owner Brian encourages customers to visit the pond headquarters and design their own version of paradise. For inspiration, watch the brief video recapping the event on YouTube.

Abandoned and neglected koi fish find shelter at Koi Show

Abandoned and neglected koi fish find shelter at Koi Show

Abandoned and neglected koi fish find shelter at Koi Show

This weekend, koi fish enthusiasts from all over Southern California will gather in Del Mar for the San Diego Koi Club’s 30th annual show and competition. Yet as prized as these oversize jewel-toned fish may be among collectors, a small segment of this scaly population fall between society’s cracks.

These are the “vagabond koi,” fish who’ve been abandoned, neglected, orphaned by an owner’s death or who’ve become too numerous or costly to maintain. Fortunately for the homeless fish, they have a protector.

Over the past three years, Jerry Myers of Lakeside has rescued nearly 3,000 koi from ponds around the county and, in most cases, found them new homes.  This weekend, Myers will host a Vagabond Koi booth at the show with 150 young fish available for adoption.

30th Annual San Diego Koi Show

When: 9 a.m. to 4 p.m. Saturday, March 4. 9 a.m. to 3 p.m. Sunday March 5.

Where: Del Mar Fairgrounds Activity Center, 2260 Jimmy Durante Blvd., Del Mar

Admission: Free. Parking is $13. 


The koi rescue group is just Myers’ latest cause. Before that, he ran an Australian shepherd rescue organization. Born into an overcrowded home in New York 62 years ago, Myers and several siblings were moved to a Catholic youth home, where he lived from ages 9 to 15. The experience of losing his family and home left a permanent impression on him and a desire to help others in need.

“I’m kind of an odd character,” said Myers, who edits the koi club’s newsletter. “If I see an animal in trouble. I have to help it. I guess I’ve just got a heart for animals.”

Vagabond Koi got its start in 2014, when Myers was working as an administrator at a medical office. A patient called in and asked if anybody would like some baby koi. Myers and his wife, Diane Conger, live on a 1.5-acre property where he’s maintained his own koi pond for 18 years.

Figuring they had the room in their pond to help out, he drove out, netted the fish and brought them home with the goal of sharing them with other club members.

Then in May 2014, the Cocos Fire swept through the Harmony Grove Spiritualist Association and destroyed much of the community. The pastor’s home was gutted and the fish in his koi pond were suffocating in the ash-choked water. Cal Fire and San Diego Humane Society officials tracked down Myers for help.

He cleaned, stabilized and aerated the pond, built a new holding tank on his own property and then with the help of club members, netted and moved all of the surviving the fish to Lakeside for safe-keeping.

When the pastor decided against rebuilding five months later, he gave Myers permission to find new homes for the fish. Myers gave away all but one, who he calls Lady Matilda.

Mike Poyner, an attorney in Mission Hills who serves with Myers on the Koi Club’s volunteer committee, said the fire awakened a giving spirit in Myers.

“Jerry has a very caring heart and he’s a man of action. When he sees something wrong, it’s like instead of cursing the darkness he lights a candle,” Poyner said. “He has unlimited energy and an unlimited desire to respond when someone needs help.”

There are many reasons people give up their koi. The fish can live up to 100 years and outlive their owners; the cost for electricity and water bills may become too expensive; or the fish may spawn and overwhelm the pond with babies. But the most common reason is the fish can grow from three inches to a foot in length in just a year, and homeowners either buy too many starter fish or their pond isn’t big enough to accommodate the adults.

After news reports aired about the Harmony Grove fish rescue, Myers could barely keep up with demand for his free services. He went from one in-ground pond for his personal collection of 30 fish to a peak of 14 ponds, and his electric bill rose from $300 to $1,100 a month.

Eventually he installed solar panels to cut his power bills, started a nonprofit to accept public donations and found a company that donates up to 100 pounds of feed pellets every month.

These days, with donations and a part-time job maintaining koi ponds for three corporate and private customers, he said he’s finally breaking even.

Myers now has about 300 fish in six ponds on his property. His new rule is to arrange a new adoptive home for rescued koi before he ever collects them, so they don’t have to endure the trauma of being moved twice. Places that received rescued koi include the Catamaran Resort, the Bahia Resort Hotel, the Deer Park Monastery in Escondido and the Mission San Antonio in Pala.

Not everyone who wants to adopt a koi can have one. Sometimes well-meaning homeowners attempt to rescue koi on their own and don’t realize the danger of mixing fish with different immunities, or they mistakenly put the fish in tap water, which has chlorine that will burn their gills and kill them.

Myers said he likes to re-home fish with homeowners who have some experience raising koi. He requires a 1,000- to 1,200-gallon pond for three fish. He wants the pond to be properly filtered, free of harmful bacteria and reasonably safe from predators like herons and raccoons.

Myers doesn’t charge for his services or the fish, though he asks for a donation to cover equipment and expenses. The adoptable fish he’ll have at the Koi Show this weekend will be $20 each, with all proceeds benefiting Vagabond Koi. He’ll also have a booth of artwork and other merchandise donated by club members. All sale proceeds will benefit the charity.

Although Myers has become well-known in the koi community for rescuing fish and helping homeowners rebuild their ponds, he generally shies away from publicity, which Poyner said is typical of his humble nature.

“Jerry has become the Johnny Appleseed of koi, planting homeless koi on ponds all over San Diego County,” Poyner said. “He never boasts about his accomplishments and he makes a friend out of every person he meets.”
