2. Parent-shrimp culture Parent-shrimp pond can promote 40-60kg/ mu of parent-shrimp, and steam bath with 3% clarified limewater for 65438±00min before free-range culture to eliminate pathogenic bacteria. In order to make rational use of water quality and regulate water body, silver carp and silver carp can be raised at 50- 100.
3. Free-range plan: Before the lobster fry enter the pond, the pond should be well combed, the silt should be removed, and the bottom of the pond should be leveled, so that the bottom and side walls of the pond have good water permeability and water leakage should be minimized. The dam should have a certain inclination. If conditions permit, a drainage ditch can be dug from the center of the bottom of the pond or ditches can be dug around the lower ditch of the pond, which is the key to the management and easy operation of lobster fry breeding in the early stage. The quality of disinfection and sterilization in pond cleaning is directly related to the survival rate and planting yield of shrimp. After the bleaching solution is melted, it is sprayed all over the pool with the dosage of 1 mu 7kg, and the dosage of bleaching essence decreases.
4, planting aquatic plants lobster meat miscellaneous, although partial animals, but animal feed is not good, but also eat aquatic plants. The aquatic plants eaten by lobsters are Sophora alopecuroides, black algae, Eichhornia crassipes, algae and Alternanthera philoxeroides. Aquatic plants are also the best place for shrimps to hide and live, and also an excellent place for shrimps to molt. There are many aquatic plants in the pond to raise shrimp, and the survival rate is very high.
5. Feeding lobsters with concentrated feed belongs to omnivorous animals, and adult shrimps can be directly fed with crushed bran, bean cake, wheat bran, miscellaneous fish, snail meat, silkworm chrysalis, loach, slaughterhouse leftovers or concentrated feed. It can be adjusted according to the season, temperature, water body and physiological condition of shrimp. The water temperature is suitable from June to September, which is the peak of shrimp growth and development. Generally, it is fed 2-3 times a day at 9- 10 in the morning and around sunset or at night.
