How to Raise Koi and Black Carp Together? Practical Experience Shared
In order to fully tap the production potential of the water body, adult fish farming mostly adopts polyculture, dense stocking and rotational culture. If carp is polycultured in the same pond with black carp, because feed is easy to obtain, it grows both fast and well. The commonly used ratio is for every 1 kg of black carp fingerlings stocked, stock 2~4 carp with a total length of about 13 cm

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
