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.Chapter 28The path is shown in the following figure:他转向众军士，高举双臂：在战场上，从来就没有一个人可以扭转战局，谁也不行。处于前线的犯罪集团在垃圾处理厂的掩护下从贩毒、赌场、谋杀等各种生意里赚取了丰厚的利益，但是黑帮内部的运作却并不顺畅。克拉多-瑟普拉诺虽然很喜欢托尼这个侄子，不过他不甘心在集团里反而位居晚辈之后，他利用托尼强悍的寡母丽维亚-瑟普拉诺来达到自己的目的。
