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.痞.子蔡鼻子突然感受到一股ph值小于7的气息，但是痞.子蔡没有哭。皇上只有在不高兴的时候才会杀人，如今东海倭乱弗朗机叫嚣，北虏俺答**京师，把兄弟暴毙身亡，杭州没了蓟辽告急，这已经不是不高兴这么简单了。　　夏林希的高三光芒四射，蒋正寒的高三危机四伏。第一次感受到爱情的两个人，明明想告诉全天下，却直到高考后才明朗地坦诚心意。两人如愿考入同一所大学，最纯真的感情和最广阔的天地，二人的感情终于天高任鸟飞。从校园到职场，从青涩到成熟，从校服到婚纱…刘邦嘴角一动What qualifications and requirements does a male kindergarten teacher need?钉钉超级发布会
