Double-season aquaculture: before the end of February, 10-15 kg of autumn shrimp species (1000-1600 kg) are stocked per mu, and the dry pond harvest is over in June and July; After the dry pond is cleared, 10,000 green shrimp seedlings (or kilograms of shrimp with eggs) are put into the mu. 2. One-time stocking annual breeding (choose one):
1) Stocking shrimp seedlings, 5-60,000 per stock, the scale of centimeters or more, the time should be in 6-7 months; (2) stocking shrimp species, 20-25 kg per mu, 1000-1600 kg, the time should be in 12-2 months; (3) Stocking egg-holding shrimp, 2-3 kg of egg-holding shrimp per mu. 2. Stocking precautions: Shrimp seed stocking should be carried out in cloudy or rainy days, and stocking should be carried out in the morning and evening on sunny days, so as to avoid direct sunlight and affect the survival rate of stocking.
Shrimp seedlings in the same pond require one-time filling. 3. Fish breeding: 40-50 silver carp fingerlings per mu of shrimp ponds, with a scale of 20-30 kilograms, should be carried out 10-15 days after the stocking of green shrimp seedlings (30 silver carp Laokou per mu).
Raising silver carp can adjust the water quality, and the second is to make full use of the water body and increase the benefits; Third, the feeding habits of silver carp can also be used to feed on the flea-like larvae of some green shrimp to control the density of green shrimp.

The shrimp fry of Jiwei shrimp are generally available in large-scale farms.
Seed stocking. (1) Seedling desalination.
At present, the shrimp seedlings used in the cultivation of shrimp are mostly factory production, and the proportion of seawater used for general seedling breeding is 1 015 1 020, and it must be domesticated first to be domesticated and gradually desalination to be moved to freshwater for aquaculture. The degree of desalination must reach the pond standard, that is, the proportion of water used is 1 003 before it can be directly transferred to freshwater for aquaculture, and the whole desalination process must be gradually desalined after more than two days.
2) The amount of seedlings.
Single-culture of new shrimp, 0 7 1 0 cm in length, 25,000 seedlings per 0 067 ha; Polyculture with freshwater fish (can only be polycultured with grass carp, bighead carp and silver carp), it is best to stock temporary shrimp fry with a body length of more than 2 5 cm, and the number of fry will be reduced according to the specific situation.
3) Temporary rearing. Dig a small temporary pond in the corner of the shrimp pond, the area accounts for about 3 5 of the shrimp pond area, the shrimp seedlings required by the shrimp pond are cultivated intensively for 15 20 days, and the shrimp seedlings are generally 1 0 1 5 cm after the overflow is naturally dispersed to the whole pond, through this method, the adaptability of the shrimp seedlings to the environment of the shrimp pond can be greatly enhanced.
Now there are very few sharks.
