Breeding method: natural breeding.
Grass carp is generally sexually mature at the age of 4, and the earliest is 3 years old. Mature females weigh more than 5 kg. The breeding season of grass carp is basically the same as that of silver carp and bighead carp, that is, April-July. The breeding season in the north and south of China is different. The Yangtze River is from April to June, and the northeast is a little later. During the breeding season, pearl stars appear on the pectoral fins of parent fish, which are rough to touch by hand. Grass fish eggs are large in diameter, about 5 mm, belonging to floating eggs. ?
The spawning grounds of grass carp are generally selected at the confluence of the main stream of the river, the deep trough water on one side of the meander, and the river sections with sudden contraction on both sides. Grass carp can produce 300 ~ 1.38 million eggs at a time. After the fertilized egg absorbs water and expands, the egg diameter can reach about 5 mm, and it can drift along the river.
