1. Blower, bottom microporous pipe aeration system and aquaculture equipment are powered, mainly including blower, PVC pipe, microporous aerator, valve switch, etc.

2. Disinfect the shrimp pond. The new shrimp pond should be exposed to water for 2 ~ 3d days, while the old shrimp pond should be cleared of excessive silt. Then, clean the pond with fresh lime to kill all kinds of pests in the water and fish that will eat shrimp seedlings.

3. Selection and transportation of parent shrimp. Parent shrimps generally choose adult shrimps. The female shrimp is required to be more than 10cm long and weigh 30g. Male shrimp is bigger. From the appearance, there should be no disability, bright body color and fat shrimp. Parent shrimp should be 12 adult shrimp with winter age. The ratio of male to female is 45: 1. 4. Key points of feeding: Macrobrachium rosenbergii is very selective in feeding. Under natural conditions, they mainly use live animal bait. Therefore, shrimp should be domesticated from an early age and eat artificial bait.

5. Improve the water quality, keep the color of water light green and light brown, and the transparency is 3035cm. At the same time, it is necessary to start the aerator regularly or inject micro-water to improve the water quality. 6. Management during the shelling. Pay attention to the prevention and control of pests when shelling: cats, water cooked, water she, ducks, egrets and other pests. Therefore, it is necessary to build a prevention and control net above the pond of Macrobrachium rosenbergii, regularly clean the weeds around the pond, or lay black films or asbestos tiles to reduce the influence of pests on the shelling period of Macrobrachium rosenbergii.

What is the difference between crayfish culture technology and greenhouse culture technology?

First of all, the adaptability of rock shrimp to crayfish is not very strong, and it can be raised in the north, south and even northeast, while rock shrimp can only survive in places with high temperature, and winter in the north is its biggest enemy. Therefore, only some places in the south will breed Luo shrimp.

Secondly, the shrimp seedlings of rock shrimp are really too expensive. In the process of breeding, feed and ultra-high technology are needed. If you can't raise it well, the loss will be really great, so Macrobrachium rosenbergii is really difficult to raise.

The third point is traffic. Live lobsters are inconvenient to transport, and dead lobsters cannot be sold, so transportation becomes a big problem. So crayfish is more popular than lobster.
