? Koi is a large fish, but unlike other ornamental fish, the growth rate of koi fry is very slow. It takes about two years to grow up to the stage of spawning and reproduction. At this stage, their body length changes are quite obvious. In the
first year, if the breeder raises them properly, their body length can reach about 20 centimeters, which is also the process of their growth from fry to fingerling. In the second year, their growth is relatively slow, and they can grow to more than 30 centimeters in general. At this time, it meets the requirements of the pond, and also meets the standard of spawning.
For young koi carp, the food they feed is different at different stages:
1. In the first three days, the breeder does not need to feed them any food, because they have yolk sacs in their bodies. It is rich in nutrients for them to absorb. Absorbing the nutrients in the yolk sac can make them adapt to the external environment better and faster, and is also conducive to their growth and development.
2. After the first three days, the breeder can prepare some water for them to eat. At ordinary times, you can also prepare some cooked egg yolks to crush and feed them, but pay attention to the amount of feeding should not be too large, so as not to pollute the water quality. When they are bigger, you can try to feed some small live baits.
