Koi carp grow mainly in the first five years of their life.
In order to optimize this growth and that the fish remain healthy, it is essential to feed them with food adapted to their organism.
It is essential to feed your koi carp several times a day because the digestive system of these fish is poorly developed, they do not have a stomach but just a long digestive tract.
By feeding them more often but in smaller quantities, you therefore promote their growth by allowing easy absorption of the nutrients from their diet.
The vast majority of the year, the amount of food to be given will be around 2% of the total weight of the fish present in the pond.
A controlled habitat is also necessary to promote rapid growth, the pond water must be continuously filtered using an efficient pumping unit.
Moreover, if your goal is to grow your carp as much as possible, know that the larger your pool, the more your fish will tend to grow because it will have space to move.
In a large, healthy and controlled pond, your carp will want to move around in search of their food, which promotes their natural instincts and growth.
Koi carp are able to live in a tank with cool temperatures, but the latter tend to slow down their metabolism, which also slows down their growth.
In order to help the fish grow all year round, the ideal is to keep the water in the pond between 25°C and 28°C.
Thus, young carp will grow better and much faster in a heated pond.
It can also be cumbersome to feed your carp several times a day, you will find food dispensers on the market that allow you to regularly distribute small quantities of food in their basin.
These devices relieve you of this tedious task while promoting the growth of your carp, optimizing their colors and avoiding the production of pollution due to uneaten food remains.
