How can the survival rate of artificially bred black carp be improved?
The maturation period of black carp is later than that of silver carp, bighead carp and grass carp broodstock, and the gonads generally struggle to reach the standard for induced spawning at the end of stage IV. Therefore, a method of promoting maturation should be adopted. 15 to 20 days before induced spawning, seine the pond to check the maturity of the broodstock, and promptly give the less mature female and male broodstock
