can Koi grow in a year? Koi can grow about 6 to 7 centimeters in a year. How big it can grow in a year is affected by many factors. For example, the growth rate of Koi carp with good genes is very fast, even up to 10 centimeters. In addition, it is closely related to the environment of Koi carp, with abundant food, good water quality and abundant space. The growth rate of Koi carp is also relatively fast.
? 1. Feeding: If you want a horse to run fast, you have to feed the horse first. The same is true for Koi. Feeding should be reasonable. Let Koi eat more food with high nutritional protein content. Small fish, shrimps, water fleas, fruits, vegetables and artificial feed are all helpful for Koi to digest and absorb nutrients, and they are also its favorite food. In the process of feeding, we should pay attention to the nutrition of bait, do not always feed a single food, and feed a small number of times.
2. Breeding utensils: The selected utensils must be strictly disinfected. For example, fishing nets and brushes must be disinfected and exposed to the sun before they can be used, because the omission of a small link will bring great trouble to the later period, and even make the koi suffer from bacterial infection, threatening their lives. Oxygenation equipment should be added to the breeding equipment, so that it can be fed in the case of insufficient oxygen. Attention should be paid to the regular observation of the skin color of the fish. Healthy koi are bright in color and lively in action.
