The transparency of water is controlled at 30-40 cm. Diligently inject water, gradually deepen the water level, apply topdressing, depending on the water quality conditions; planting green area accounts for 25-30% of the water surface, not only for shrimp habitat, but also adjust the water quality; water disinfection, every half a month for every cubic meter of the whole pool 25 grams of lime slurry sprinkling, stabilizing and improving the quality of water, help shrimp growth, skin and water disinfection. Feeding management. After hatching shrimps, in addition to topdressing natural food, they are supplemented with soya milk or steamed egg yolks every day. Use 1-3 kilograms of soybeans to grind the pulp or mu for 4-5 eggs. After 10-15 days of cultivation, wheat flour, Fu Pi, fish meal, etc. can be fed into a dough-like dip or fed with larval shrimp pellets (the daily dose accounts for 4-5% of the seedling weight). Each acre nursery pond in the whole period (about 30 days), about 100 kilograms of materials, can be bred into 1.5 cm about 40,000-500,000 shrimp seedlings.
