When the fish is 2-3 cm long, 1.5-2 kg of rice bran should be put into every 10,000 fry every day. Wuping and Euphorbia humilis can also be fed in the later stage of cultivation. Appropriate dilution and intensive cultivation of cultured fish species are appropriate.

In a suitable feeding environment, if 65,438+00-65,438+05,000 fish fry are put into each mu, it can grow to about 3 cm after 65,438+05-20 days of cultivation. In the current production, when the fry are generally cultivated into summer flowers of about 3 cm, they are moved to adult fish ponds to raise commercial fish. Adult tilapia mainly feed on plankton and organic debris, so the water quality should be fertile whether it is raised alone or mixed with domestic fish.
