10-15% of aquatic plants and hidden objects are planted shallowly at the edge of the pond to create an environment for lobsters to inhabit and shell and reduce mutual killing. The influence of water quality on lobster yield cannot be ignored. During the breeding process, the PH value of the pool water is kept between 7.5 and 8.5, and the transparency is 30-40cm. Fresh water should be added frequently, quicklime solution should be splashed regularly, water quality should be adjusted, and diseases and shelling failure should be prevented. 2. Feed feed reasonably. Lobsters will kill each other when hungry and under-fed, so the feeding amount must be sufficient. Lobster feed is animal and plant feed. Plant feeds are wheat, aquatic plants, rapeseed cakes, etc. Animal feeds are miscellaneous fish, miscellaneous meat, livestock viscera, etc. At ordinary times, the feeding time, feeding amount and feeding method are determined according to the habit of lobsters falling in the day and coming out at night and the density of lobsters in the pond. 3. Scientific fishing. Young shrimps can grow to commercial specifications in 60-90 days under the condition of suitable temperature and sufficient feed. The seedlings will be released in March and will be caught in rotation around June, selling large ones and keeping small ones.AppleTV+未播先续订《#天黑请回家#HomeBeforeDark》第二季3.
