What should I pay attention to in lobster culture?

First, pond conditions. The pond water surface should not be too large, suitable for water surface 1 ~ 2 mu, water depth 1 ~ 1.5 m, with perfect drainage system and aeration system; There is a slight slope at the bottom of the pool without leakage, and the escape prevention facilities are repaired.

Second, shrimp fry stocking. After 7 ~ 10 days, the seedlings can be released after disinfection with lime water, which requires high water temperature. The suitable growth water temperature is 20℃ ~ 30℃, and it is rarely eaten below 15℃.

Third, feeding. After the shrimps are put into the pond for 30 minutes, feed is started. In the early stage, cooked soybeans were fed and beaten, supplemented by a small amount of small miscellaneous fish and snail meat. The feeding amount is 6-8% of the shrimp's weight, and it is fed twice in the morning and evening.

Fourth, daily management. ① Strengthen water quality management to ensure adequate dissolved oxygen and fresh water quality. (2) Prevent shrimps from floating in high temperature season and increase aerators. (3) When the water quality is too fat, kill plankton with quicklime and fill the pool with water. (4) Pay attention to patrol the pond to remove enemy creatures, frogs and snakes.

V. Disease Prevention and Control:

Black gill disease: After continuous rainy or rainstorm, due to the shallow turbidity of pond water, water pollution, insufficient illumination, mold infection and other reasons, the gills of some diseased crayfish changed from red at first to brown until they turned black completely, and the diseased gills gradually lost the function of filtering water and supplying oxygen, and the gills gradually shrank.

Prevention and control methods: spray bleaching powder 1g per cubic meter of water in the whole pool, or spray 0.6g ozone compound preparation per cubic meter of water in the whole pool, and apply it twice a day. After 3 days, sprinkle 5 grams of photosynthetic bacteria on every cubic meter of water; Add 0.2% stable VC to the feed and feed it continuously for one week.

Extended data:

Pay attention to the tail when buying lobster.

Like most creatures in nature who bully the small by the big, there is also a phenomenon that prawns eat prawns in the lobster world. Most of the lobster's meat is hidden in the tail. Sometimes a shrimp looks alive and kicking, but maybe its tail has been eaten almost by the prawns who live together. Therefore, when buying lobster, please pay attention to the tail of lobster, and gently pinching it with your hand is the best inspection method.
