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.一名孤独的探险家死去了，他那破旧的、包有皮边的笔记本便成为因时间而淡忘了的史前高原探险活动的惟一的线索。在伦敦，爱德华·查林杰教授召集了擅长不同领域的冒险家，组建了一支探险队，决心证实遗失的世界的存在，在地图上未标明的丛林中探险。在亚马逊丛林一片被时间遗忘的高原土地上，科学探险队的几位成员在寻找离开高原的路径。他们必须防御来自原始部落猎人们的袭击。他们在野外的高原上遇阻，无法返回，而这里又是一个令人害怕的世界，时常出没一些史前的食肉动物、原始的猿人、奇特的植物和吸血的蝙蝠。对研究史前生物的人来说，这里是天堂，而对普通的旅游者来说，这里却象地狱一样。但是为了生存，这群命运不济的人必须团结起来，抛弃个人之间的喜好和偏见，随时准备应付任何可能突发的情况。在野性丛林美女维罗尼卡的帮助下，手中只有几只猎枪的他们用智能一次又一次摆脱了死亡的威胁。美国地方剧院（American Place Theater）的联合创始人/导演、表演老师韦恩·马曼（Wynn Mamen）的生平和职业生涯。Each method will be called in turn.
