How to Select Young Koi Fish? A Detailed Guide to Fish Selection Methods
How do you select young koi fish?
The process of raising fry is also a process of selecting the superior and eliminating the inferior, a process of selection and cultivation carried out multiple times. The selection process is generally carried out 3 to 4 times within 3 months after the fry hatch.
Second selection: carried out within 20 to 30 days after the fry hatch, starting when the fish have grown to about 3 cm in body length. The main purpose is to keep individuals that are robust in constitution, lively in swimming, and obvious in breed characteristics, while eliminating the others or raising them separately for sale. However, because breeds differ, their growth speed and the time at which markings form also differ. For example: Showa Sanshoku koi begin selection about 15 days after hatching, Ogon-type koi begin about 50 days after hatching, and Kohaku and Taisho Sanshoku series koi begin about 60 days after hatching.
Second selection: begins about 20 days after the first selection. The selection criteria are the quality of the fin shape, whether the colors are bright or not, whether the pattern markings are clear, and whether the breed characteristics are obvious, and so on.
Third and fourth selections: basically the same as the second selection.
