Embodiment

[0020] Embodiment: a kind of method for the artificial propagation and breeding of red bream with cocked mouth, mainly comprises the following steps:

[0021] (1) Select broodstock

[0022] The quality of broodstock is the key to the success or failure of artificial breeding and seedling breeding. Due to the limitation of natural resources and the difficulty of surviving broodstock after launching into the water, the selection and cultivation of broodstock for breeding is even more important. If the broodstock collected from natural waters Different reproductive groups have different physical conditions, gonad development sooner or later, and ecological conditions are different under natural conditions and artificial breeding conditions. In order to ensure that the broodstock can reach the maturity of gonads in artificial breeding, they should be fished from Taihu Lake in autumn and winter. Broodstock with no injuries on the body surface and a size of more than 2 kg can be tem...
