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.战国时代，礼崩乐坏。周天子狩猎大典遇刺，七国诸侯与后妃臣公皆有嫌疑。危机四伏，波谲云诡，精心布局的阴谋环环相扣。战火烽烟，诸侯并起，大时代中，秉承理想与信仰的旷世奇才鬼谷子王蝉，踏上了勤王之路，与门生孙膑、庞涓、苏秦、张仪等壮志凌云之士，前赴后继，匡扶正义，拯救天下。《从海底出击》续订第二季。胡钧等人忙下马参见，又寒暄问道：大人这是往哪去？他不好再称呼何风为副将军，又怕称呼指挥使让何风觉得刺心，于是就含糊地称呼为大人了。"Wenchuan earthquake saved me."
