The selection of juvenile fish is the most important step to obtain high quality koi in the process of breeding. Generally, 4 times of 3mi selection were carried out within more than 3 months after hatching. The selection time varies with different varieties, the speed of growth and the time of appearance of markings.

For example, Zhaohe tricolor koi is selected after more than two weeks of incubation, gold system koi is selected in 50 days, and red and white and Dazheng tricolor koi are selected in about 60 days. In short, the selection begins when the young fish grow to a body length of 3mi 5cm.

The breeding of koi can be divided into the following points:

1. Breeding space: koi can be raised in aquariums or fish ponds because of the environmental regulation of body shape. Don't put too many decorations in the aquarium so as not to hurt the fish.

2. Water temperature: the range of water temperature for koi is 2 ℃-30 ℃, and the most suitable water temperature for life is 20 ℃-25 ℃. In the water at this temperature, koi swim actively, have a strong appetite, have a strong physique and have bright colors. Due to the use of aquarium breeding, so the temperature can be controlled in the range of 20 ℃-25 ℃ throughout the year, so that koi can have a comfortable environment and grow rapidly.
