Koi fish overpopulation is one of the hardest problems to deal with when it comes Koi ponds.

Once you have to many fish in your pond, severe problems can
occur, and potentially cause death among your fish.

There are a few ways to help prevent koi fish overpopulation. While you
are never guaranteed that it will never happen to you, following a
few simple steps will greatly reduce you chances.

Do Not Overstock

A common problem new Koi pond owners run into is over stocking.

When you first go to buy your Koi, it may come down to deciding
between a number of Koi that is equally beautiful and playful in the
spirit of saving your pond from over stocking.

Talk with your Koi dealer or Pet Store professional about the specifics of your pond.

You should tell them information about what type of filtration
systems you have, what total size your pond is, and where you are planning on placing your pond.

With this information, a professional will be able to adequately
predict the right amount of Koi you can have in your pond successfully.

Do not worry if this number seems small, because the professional
will also be taking into account the fact that Koi grow fast and get rather large.

Some people run into the problem of not being able to turn down Koi from others.

When accepting fish from sources such as other Koi pond owners,
take into account why they are giving you the fish.

Chances are they are giving away fish because they are having
issues with Koi fish over population as well.

Turning down fish does not mean that you are causing any damage
to those fish, it simply means that their owner will have to find a different person to take the fish.

Once Koi Fish Overpopulation Has Occurred

In the event that overpopulation has already occurred in your
pond, there are several ways of removing babies from your pond.

One way is to stop feeding your Koi the minute you realize that spawning has occurred.

You should stop feeding your Koi for no less then three weeks. Do not worry about your Koi starving, as they will focus more on natural foods if you are not feeding them daily.

This “natural” diet includes their young. Koi are not cannibalistic
animals by any means, but they will eat their young when they are
still eggs or if they are small and resemble insects.

Once the baby Koi actually resemble real fish, and the adult fish
recognize this, they will no longer see them as food, so it is
important to start this process as soon as you notice spawning or babies.

While this is a process of nature, you may still find this method to be cruel or unusual. Another way of removing unwanted babies from your pond is to give them away.

First, check with your local pet store. Many pet stores have
programs in which they will accept unwanted animals and give them good homes.

Some may even pay a certain amount for each fish since they sell them, but do not count of this. Local Zoos may also have programs.

If you know of a local Koi society, you may let them know that you have unwanted babies. Alternatively, you can find a message board or group online and post messages there. Who knows, you may even start another person on a Koi keeping hobby.

Will koi fish eat their babies?

Because koi fry have such small mouths, they need smaller sized food.

Koi fry need to eat liquid or small suspended-particle food for their first few days of life. After that, you can work on feeding your koi fry larger and larger solid foods.

Baby koi can eat food out of your refrigerator, such as hard boiled eggs.

Do big koi eat little koi?

Koi are omnivorous and they may eat Koi fry or eggs, but they will leave smaller fish alone.

Medium, large and jumbo sized Koi are priced on a per fish basis
depending on: size, body conformation, skin luster and color.

How long can koi fish go without food?

Many experienced fishkeepers routinely leave their charges for two
to three days without making any provisions for feeding.

Almost any fish can go that long without fish food (more about that later, as well).

However, if you’re going away for longer, some preparation may be needed.
