The influence of water quality on lobster production can not be ignored. The quality of water directly affects the healthy growth and development of lobsters. In the process of culture, the PH value of the pond water is maintained at 7.5-8.5, and the transparency is 30-40 cm. It is necessary to add fresh water frequently, spray quicklime solution regularly, and adjust the water quality to prevent diseases and incomplete shelling.
The second is to feed the feed reasonably. Lobsters will kill each other when they are hungry and lack of food, so the feeding amount must be sufficient. Lobster feed is animal and plant feed. Plant feed is wheat, aquatic plants, rapeseed cake, etc. And animal feed is miscellaneous fish, miscellaneous meat and internal organs of livestock. Usually, the feeding time, feeding amount and feeding mode are determined according to the habit of lobster lying in the daytime and coming out at night and the density of shrimp in the pond. Otherwise, it will increase the feed cost and reduce the breeding benefit.
The third is scientific fishing. In the process of lobster culture, under the conditions of appropriate temperature and sufficient feed, young shrimp can grow to the commercial specifications within 60-90 days. Seedlings will be released in March, and rotation will start around June. The big ones will be sold and the small ones will be kept. Because of the large catch and small catch, the fishing rate can be improved and sold at a good price to achieve the goal of high yield and high efficiency.
