How much koi food can a koi carp get?

The amount of koi food that you can best give your koi carp depends on a number of factors. Age is an important factor, because young koi carps have to grow considerably and eat up to five times more than older koi.

Apply the following rules of thumb when feeding:

  • Don’t panic when your koi carps are much wilder when fed than someone else’s. If you have a lot of koi carp, food envy may occur. However, this is not a sign that your koi is short of anything.
  • It is better to give less koi food at a time and to distribute the total amount of food over more feeding moments. You can also buy feeding machines that take care of the feeding for you.
  • Do not feed more than your koi carps can eat in about five minutes.
  • Keep a guideline of 2 kilograms of feed per 100 kilograms of koi per day in your pond. This applies at a temperature of around 21 degrees Celsius. If you go to a temperature of 25 degrees Celsius, then it will be 3 to 3.5 kilograms of feed per 100 kilograms of koi. And below twenty degrees Celsius you go to about 1.5 kilograms of food.
  • Don’t give koi carps too much koi food, because this will pollute your water more through extra stools and food that remains in the water.
  • If you have not heated the koi pond of your koi carp, you will have to take the temperature of the pond water into account when feeding.

If you have not heated the koi pond of your koi carp, you will have to take the temperature of the pond water into account when feeding.

If the water falls below approximately eight degrees Celsius, it is better not to feed your koi carp. The fish cannot digest its food in this cold water, because its metabolism is too slow at these temperatures. The only thing that happens is that you contaminate the water with food or that the food remains undigested in the stomach of your koi carp.

At a temperature between eight and fourteen degrees Celsius you can feed the koi food products based on wheat germ. From fourteen degrees Celsius you can give your koi carp the normal food, possibly at a higher temperature supplemented with extra proteins.
