koi japenese fish

koi japenese fish Koi Japanese fish are from the carp family and have made their way round the world since their introduction.

There are over fourteen varieties of Koi with red, blue, yellow, black, white, and purple being common.

Also known as, Japansese carp, these fish are kept for decorative purposes in ponds and many traditional Japanese gardens.

For decades, Koi has been a symbol of love and friendship. Koi tattoos are popular even in North America today.

The types of Koi are distinguished by the color, pattern, and scales. Gosanke, Taisho Sanshoku, and Showa Sanshoku are the popular varieties.

Koi Japanese fish can be found in many countries since they adapt easily to climatic conditions, much like carp.

The color and physical appearance is what makes them ideal decorative pieces for ponds and water gardens.

Koi are known to live for at least twenty or thirty years when looked after properly.

Moreover, they grow rapidly to over a foot long when kept in a large pond and fed regularly.

Like many other fish, they do not grow fast in smaller water bodies. Although they are coldwater fish, they thrive in temperatures between 60-80 degrees F.

As the carp represents wisdom and longevity, so does the Koi Japanese fish.

Their natural tendency to swim upstream against the flow of water is a symbol of perseverance and resolve.

This has been the focus of many Japanese legends and stories where Koi are able to climb waterfalls and become dragons.

Many Koi tattoos are based on these stories.

The colors of Koi Japanese fish often put them at a disadvantage against predators such as cats, herons, badgers, hedgehogs who are all eager to have them for their meal.

Therefore, it is essential to have a well-designed outdoor pond if you plan to breed Koi.

A deep pond will keep herons away, while overhangs and tall, shady trees will keep them well protected.

It would be a good idea to string nets or wires over the pond for extra protection.

Koi eat a variety of foods so you can include peas, watermelon, and lettuce in their diet.

You can train them to take food from your hand once they recognize that you are the source of their food.

During winter, Koi Japanese fish tend to eat less since their digestive system slows down, until the temperature increases in spring and summer.

Koi reproduce through spawning and can produce thousands of offspring in a single spawning.

Not all turn out to be of the best grade. The defective ones are sorted and culled, and sold as lower grade Koi or as feeder fish.

If you plan to add Koi Japanese fish to your pond you need to make sure that the chemical level of the water is suitable.

De-chlorinate your pond and maintain the appropriate PH, ammonia, and nitrite levels.

There are plenty products available in the market to help you measure chemical levels.

Never introduce the fish directly into the water. Keep them in a bag with a slight opening and place it in the pond.

This will allow the fish to adapt to the new water. Carefully release the fish from the bag after an hour.

A good idea is to start with only two or three fish. This will give you time to determine whether they are healthy.

Refrain from feeding them on the first day. Once these Koi adapt to the conditions you can add more to your Koi pond, and wath your school grow.

Koi Fish Breeding Tips

Koi Fish Breeding Tips The moon is full. It reflects off the water of a fishpond full of koi. It is April and the koi are getting ready to breed.

For some, this is an unexpected event that leads to the sudden
intrusion of many new fish in their formerly spacey pond.

But for other koi owners, this is an exciting and anticipated time of year.

Those who are excited about breeding koi fish, start the preparation
well in advance of the April to July breeding season, and their hard
work pays off in superb koi of exceptionally high quality.

Breeding koi fish can be a challenge, in part because of the sheer size of the fish.

Koi can grow to be large, which can pose a problem when trying to find space for newly-bred fish in a pre-existing pond.

Having plenty of space for all the fish, including both the parents
and their offspring, is crucial to the health of all the fish.

It is also vital to get good, high-quality fish to breed. High-quality offspring can only come from high-quality parents

. If you are looking to buy koi for breeding, you will have to be
knowledgeable on exactly which type of koi you want and what the
signs of a healthy, high-quality fish of that type are.

A good place to start is the coloring and pattern on the fish.

The vividness of the colors and crispness of the distinction between
colors can often indicate the quality of the fish.

Also look at the age of the fish you buy for breeding. Both too young and too old can be detrimental.

A very young female koi may have eggs that are too soft, and therefore more easily prone to damaging.

You could lose many of the offspring produced by a young koi. On the other end of the spectrum is a koi that is too old.

As you may expect, this sometimes leads to the opposite problem. An older female koi could produce eggs with shells that are too
hard, which may prevent sperm from being able to fertilize them. The ideal age is four to five years old if the koi is intended to be used for breeding.

The weather and even the moon can affect breeding. Koi like to
breed during a season when the difference between the high and
low temperature for the day is very slight.

They also like to breed during the full moon. If possible, aim to have your fish breed when the moon is full or nearly full, as this helps encourage the fish to spawn.

One spawning can result in literally thousands of eggs. The male fish will fertilize the eggs after they are out of the female.

The male will also try to help the female release the eggs by pushing her from each side.

Watch the fish carefully during this to ensure the male does not injure the female.

Even if you’ve done everything correctly up to this point and gotten your fish to breed, your work is not quite done yet.

Even after breeding there are steps to be taken to ensure the
continued health of your fish and their offspring.

Separate the fish after the spawning to allow the female to rest.

After this point, it is your responsibility to take care of your new fish and their parents.

With diligence, attention and care, your pond may soon be full of
high-quality, individually bred koi guided from egg to maturity by you.

How many eggs do koi fish lay?
It is possible though that younger Koi will breed but their offspring will be of poor quality. The female is capable of carrying around 100,000 eggs for every 1kg of body weight. So a female of 10kg in weight will pass 1,000,000 eggs of which 60% will hatch.

Is breeding koi profitable?
Koi breeding can be profitable in one of two ways: 1) You raise baby koi fish and sell them when they are much larger. 2) You breed purebred koi fish varieties for a living. … Make sure to give your breeding koi couple some privacy when it’s time for them to mate. Koi need a place to lay their eggs.

Koi Fish Breeding Tips

How do koi fish reproduce?
In a pond setting, koi will breed as a flock, or group. … During spawning the male koi will become extremely aggressive. Male fish will pursue the female koi around the pond, smashing into them repeatedly. This battering behavior is designed to force the eggs from the female’s body

Barebones Requirement for Koi Pond

Barebones Requirement for Koi Pond

Whatever you’re reason for wanting to start a Koi pond; you may find the range of options to be quite overwhelming.

It is feasible to spend thousands and thousands of dollars on your
Koi pond before even purchasing any fish!

If you’re just starting, however, you may want to start with
something a little more budget friendly to determine if Koi ponds are right for you.

This guide will cover the absolute essentials of setting up your first
Koi pond for just a few hundred dollars and some honest elbow grease.

In the future, you may become a very successful Koi breeder, but
for now let’s focus on setting up a functional pond that do well enough to keep your fish healthy and happy.

After you get the pond in place, functioning, and stable enough to
support the Koi you purchase—then, and only then, would you
truly be ready to sink into the investment of purchasing the Koi fish themselves.

To begin, you will need the following five items:

1.) A Pond Liner – Simply put, a pond liner will hold the water in your pond. If you dig a hole in the ground and put water in it, it will be absorbed into the soil (unless you’re talking about a LOT of water).

Furthermore, you want to separate you Koi’s environment from
outside contaminants as much as possible. Consider either uPVC
or Butyl; both are readily available from your local home improvement store.

If your hole has lots of sharp rocks in it, you may want to purchase some extra layers or padding to protect the liner.

Since the padding will not come in contact with the Koi, anything
resistant to shredding will work, even an old rug.

2.) A Filter – You cannot have a Koi pond without a filter. Your
filtration needs will depend on the volume of your pond, which
means that if you want to save you should start will a smaller pond.

Unless you are skilled in fabricating your own aquarium filters, you
would be best served by purchasing a filter in the store.

You need a filter to remove debris, bacteria, and toxins from the water.

If you’re working on a budget, take a good look at the filter prices
and their recommended replacement intervals making sure to
factor that cost into your calculations.

3.) A Pond Pump – This will work in conjunction with the filter to clean your pond water.

It is absolutely essential to your Koi’s survival to have a working pump at all times.

If you can afford it, you should always keep a backup pump on hand in case of a failure.

Make sure to check with your aquarium supply dealer regarding pump efficiency.

A general rule of thumb is that your pump should be able to circulate the entire pond’s volume within a couple of hours.

4.) A UV Clarifier – This is a special piece of equipment that fits between the pump and the filter.

It uses UV rays to help the filter remove algae from the pond water. Algae are a special concern in Koi ponds since it is often too small to be caught by most filtration systems.

The UV rays will cause algae particles to bond together so that they
are large enough to be filtered out of the water.

It is feasible to remove algae from the pond by chemical methods,
but this is considered hazardous to the Koi.

5.) A Test Kit – Even experts need test kits. The quality of your Koi’s water must be checked frequently.

One of the most dangerous chemicals to your Koi is ammonia, which can be detected by neither sight nor smell.

You will need two different types of test kits, one for pH, and one
for nitrate (which will indicate filter performance).

Ensuring the quality of your Koi’s water is a major factor in how long they will survive.

This process may sound easy and promising if you’re considering
breeding Koi for fun or profit, but many factors must be exactly
right for even a small percentage of these eggs to survive so don’t get your hopes up just yet.

A pregnant female will be relatively easy to notice among other Koi. They will, of course, appear larger, mostly in the abdomen.

Pregnancy, however, does not equate to fertility in the fish world.

The eggs must be fertilized by a male, and determining when a male is ready to breed is not as easy.

The next most-important factor is an appropriate breeding setup.

Generally it is preferable to conduct Koi spawning in controlled
environment, separate from the other Koi that you may have.

Since the water parameters most appropriate to encourage
breeding are somewhat stressful on the Koi, it is best not to place
the entire flock under this type of strain unnecessarily.

Also, when keeping the spawning pair separate from the rest of the
flock, you can better ascertain the type of Koi you will produce if you are trying to cross-breed.

Furthermore, you will have much more control over the fate of the
eggs, which will improve the overall survivability of your Koi babies.

The ideal setup will have plenty of room for both fish. Expert opinions vary, but temperature should be somewhere around 2-5°C higher.

Always remember to give the female an area to lay the eggs; they will need something to attach to.

Plant matter tends to work best, but even experienced breeders
have been known to use a solution as simple as a mop head to save costs.

Always keep the eggs separate from the rest of the flock. If left open to the adult Koi, they will likely be eaten.

Additionally, it is best if there are some “private” areas within the
breeding enclosure, basically anything that gives the impression of a nest.

Again, some plant matter or even fish netting will work well for this effect.

Koi will naturally breed in the spring. They can sense the time of year through changes in the water temperature.

It would be considered extremely difficult to simulate this, so it is
best to allow this to occur naturally.

If the pair will breed, they will very likely do it in the morning. All of the conditions must be just right.

If they do not breed, try adjusting the water temperature; it may be too cold or too warm.

Make sure they are well fed. You can keep trying, but it is only recommended to keep the Koi in the breeding enclosure for a few days at a time.

They may perish if exposed to the high temperatures for too long.

The eggs, if fertilized, will hatch in seven to ten days after the spawning.

While it was said that Koi will lay thousands of eggs at a time, do
not raise your expectations that each one will survive.

Not all of the eggs are going to make it and you should not expect
thousands of little Koi swimming around for your money making.

Make sure that you set your standards lower and don’t base your
budget on the hopes of thousands of Koi offspring in each batch of two mature Koi.
