The growth of lobster is related to bait, environment, water quality and the number of molting, and all links are inseparable. 1. The aquaculture pond requires that the aquaculture pond should be located in a place with sunny ventilation and pollution-free water quality, with a specification of 5 mu ~10 mu, a water depth of more than 1.5 m, a flat bottom of sand and mud, and a slope of 25 ~ 30 at the pond side, with convenient water intake and drainage conditions and anti-theft measures. A certain number of stones, tiles and other shelters should be placed in the pond, or more than 300 old tires should be placed per mu as a hidden habitat for shrimp. 2. Shrimp fry can be stocked in April. Shrimp fry with a body length of 3 cm ~ 5 cm can be stocked with 5,000 ~ 6,000 per mu, and the small shrimp fry can be appropriately increased. However, the shrimp bullies the weak and fears the big, so the specifications of the fry stocked in the same pond are neat. When releasing seedlings, it is necessary to avoid too large a difference in water temperature, and it is appropriate to pool at dusk or at dawn. Before releasing the seedlings, slowly add a small amount of pond water into the seedling container to adjust the water temperature until the water temperature in the container is close to that of the pond water, and then gently put the shrimp seedlings into the pond. Third, do a good job of feeding According to general experience, the daily feeding amount is subject to eating, eating, and leaving no residual bait. Generally, shrimps are fed at 20% ~ 25% of body weight, middle shrimps at15% ~ 20%, and prawns at 5% ~10%. Feed it twice a day, once in the morning and once in the evening, 70% ~ 80% of the total daily feed, and feed it in the shallow water of the pond. Too little bait will inhibit the growth of shrimp, but too much bait will not only increase the cost, but also worsen the environment in the pond, which is unfavorable for the growth and shelling of shrimp. The feed can be general shrimp feed, adult shrimp feed and small miscellaneous fish. Iv. Strengthening feeding management In daily management, besides observing the feeding, activities and growth of shrimps, attention should also be paid to water quality and bottom environment. When the dissolved oxygen content in the water is very low, the water quality deteriorates, or in severe weather such as thunderstorm, sultry weather and continuous cloudy days, feed should be reduced or stopped. When the weather is too cold or too hot, in order to prevent the extreme temperature, the pool water can be deepened appropriately to stabilize the water temperature at the bottom of the pool. In breeding, we should also pay attention to preventing diseases, eliminating the enemy of gulls and wild fish such as perch, catfish and mandarin fish. V. Harvesting and Capturing The shrimp grows fast. It can be harvested and marketed in the same year when it is stocked in the same year, and can be captured in dry ponds or purse seines. If the aquaculture yield is high and a large number of products are listed in batches, trawling or casting nets can also be used for fishing and trapping. When catching, the effect is better when it is dark at night.
