How to select the young koi?

The breeding process of fish fry is also a process of selecting the good and eliminating the bad, and it is a process of selecting and cultivating many times. The selection process is usually carried out 3 or 4 times within 3 months after hatching.

The second selection: within 20 to 30 days after hatching, when the fish grows to about 3 centimeters. The main purpose is to select individuals with strong physique, active swimming and obvious breed characteristics, and eliminate other individuals, or cultivate and sell them separately. However, due to different varieties, the growth rate and the time of speckle formation are also different. For example, the selection of Zhaohe tricolor koi began about 15 days after hatching, the golden koi began about 50 days after hatching, and the red-and-white series and Dazheng tricolor series began about 60 days after hatching.

Second selection: start about 20 days after the first selection. The selection criteria are whether the fin shape is good or bad, whether the color is bright or not, whether the pattern pattern is clear, whether the variety characteristic is obvious, and so on.

The third and fourth selection: basically the same as the second time.
