【Abstract】 In this practice, "No.2 Yuxuan Yellow River Carp" of 4+ years old were used as the parents, and large-scale reproduction was carried out by the way of “artificial spawning—natural insemination—incubation of hanging eggs”in late May 2023. A total of more than 7 million Zygotes were harvested and 6.2 million fries were incubated. Among them, 5 million were sold, and 1.2 million were cultivated in the farm. This practice will assist in the promotion of characteristic varieties of Yellow River carp in Henan Province.更多还原
