1, pond main cultivation: pond area 1-6 mu, suitable water depth of 2-2.5 meters, and pond bottom material is black loam. Fish schools are generally selected from June to July every year, with specifications of 6-8 cm and 0/000-3,000 fish per mu, and can be increased to 3,000-4,000 fish if conditions are good. Can be fed with plant feed such as soybean, bean cake, bean dregs, peanut cake, rapeseed cake, rice bran, etc. Green feed is mainly the tender leaves of various terrestrial plants and aquatic duckweed with little cellulose; Animal feed includes fish meal, silkworm chrysalis, blood meal, meat of various aquatic snails, viscera of animals such as small fish, shrimp and cattle, various terrestrial earthworms, insect larvae, etc. Artificial compound feed is usually made up of fish meal, rapeseed cake, cotton cake powder, peanut cake powder, wheat bran, minerals and vitamins. Protein content is about 28-32%. After 4-5 months of cultivation, the specifications of hybrid perch can reach 200-250g, and the yield per mu can reach more than 500kg.

2. Pond polyculture: Hybrid sunbass, silver carp, grass carp, mullet, soft-shelled turtle and so on are polycultured in ponds mainly for flower culture. Can achieve a good complementary effect. Ponds that mainly raise carp, crucian carp and bream are not suitable for mixed culture or a small amount of mixed culture of hybrid sunbass. Generally, there are 300-500 fish with the density of 6-8CM per mu. After 10 months of culture, 8-20 kilograms of hybrid perch can be obtained per mu, and the specification can reach more than 0.4 kilograms. 3. Running water culture: The culture pond is generally a cement pond of 60- 100m2, or an incubation pond and a seedling pond of about 20m2, and the water depth is kept at 1 m ... to stock 6-8cm of fish and feed them with complete compound feed containing more than 32% of protein.
