(1) water (deep, wide, alive and fresh): it is required that the water depth is appropriate (1.5-2.5m), the water source on the worry-free surface (5- 10 mu) is sufficient, the water quality is good, there is no water leakage, and the water intake and drainage facilities are complete. (2) Species (improved varieties): improved varieties with large specifications, strong physique, strong disease resistance, wide eating habits, fast growth, good meat taste and convenient seedling source. (3) Bait (the bait is all fine fertilizer): broaden the source of feed, ensure the supply of feed fertilizer, reasonably feed and fertilize, and implement "four fixed" feeding; Fertilization should be based on the weather, water quality and fish activities, and the principle of less diligent application. (4) Close planting (reasonable close planting): According to the fish pond conditions, the number of fish species, the source of feed fertilizer, aerobic equipment and management level, the stocking density is appropriate. (5) Polyculture (multi-polyculture): fish with different habitats and different bait bases are stocked, so that the water surface can be used three-dimensionally, the bait can be fully utilized, and the unit yield can be improved. (6) Round fishing (round fishing, round release): catch big fish and keep small fish, so that all the fish can be released at one time or released in stages, and caught in stages; (7) Prevention (prevention and treatment of fish diseases): the principle of early treatment and early prevention is adopted, and prevention is more important than treatment. (8) Management (careful management): special personnel management, scientific fish farming, reasonable feeding and fertilization, early seedling catching, attention to patrolling the pond, prevention of flooding and fish escaping, observation of fish activity, regular inspection of fish bodies, and good pond records.
