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.富商凌显光的大福百货公司濒临倒闭，其女家敏劝他让万众银行董事长郑世昌入股。光认为敏野心太大，不予信任，反与从美回港的家业共谋对策。惜业不幸撞车身亡，光饱受丧子之痛，又被昌压逼，遂宣布破产。敏、昌吞并大福的计划告吹，敏为发展事业，利诱林灵芝离开昌，然后与他结婚……此女子善舞，没一个舞姿都是那样的优美，那样的恰到好处，那样的动人。一名警官奋力找出杀害她作为一名卧底警察的丈夫的凶手，但事实远比她想的要黑暗。Form Validation这时有人突然想到，就算《寻秦记》是科幻小说，那又如何？科幻小说在华夏依然是偏小众。
