1, pond conditions The main site for artificial breeding is the pond, which requires sufficient water, clear water quality, convenient drainage and irrigation, and cannot be near the polluted area. The area should not be too large, just 3-5 acres. The water level of the pond is1-1.5m.. It is required to have a water inlet and a water outlet, and it is best to have a mesh cloth at the water inlet and outlet to avoid shrimp escaping when entering and leaving the water. The bottom of the pool is flat, and the soil is preferably loam and clay. Sludge was removed to less than 15cm, and an aerator was added.

2. Breeding preparation, shrimp stocking, feed feeding and pond management.

Brief introduction of freshwater shrimp

The Latin scientific name of river shrimp: Macrobrachium nipponense, also known as Macrobrachium nipponense, is an arthropod belonging to Macrobrachium nipponense. Widely distributed in rivers, lakes, reservoirs and ponds in China.

Generally, shrimp seedlings can be raised in late May when the water temperature is stable at 18 ~ 20℃. Shrimp seedlings need to be diluted for more than a week, and the proportion is below 1.003 before they can be stocked. Generally, 30,000 to 40,000 shrimps with 0.7 ~ 1.0 cm are put per mu, and seedlings below 0.7 cm are temporarily raised. 80 ~ 10 ~ 20 cm silver carp can be mixed in shrimp ponds.
