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.　　两门亲事皆含胁迫也实属无奈，弄得不好，前者的红喜将变成白喜，后者的高攀将换来替父受罪。二位小姐都在为各自的苦命暗自悲泣。谁知出嫁那天，发生了一件谁也料想不到的事情。两支送亲队伍同时出城，途中突然大雨倾盆，两路人马涌到一座庙内避雨，慌乱之中，轿夫们抬错了花轿:该送往金州的花轿被抬往林州，应抬往林州的花轿由香港无线电视制作的现代时装医务纪实电视剧《妙手仁心3》是《妙手仁心》系列的第三辑，监制戚其义与编剧周旭明的黄金组合更是精心打造此辑“妙手系列”。此辑剧集在风格上延续了前两辑经典之处，一如既往的得到医务人员协助实景拍摄，继续讲述医护人员在工作中的点滴故事。神奇校巴的孩子们冲向轨道，进入国际空间站，却发现他们需要逃离一只巨型缓步动物！进来之前，洪霖叮嘱过他。　　第二次世界大战爆发了，出狱后的罗比和塞西利亚都投入了保卫祖国的战斗，布利奥妮放弃到剑桥升学成为一名军队医务人员。没有人能理解她的做法，只有她知道她怀揣着巨大的秘密和自责。她鼓起勇气，想把这秘密解开，能真正赎罪和得到宽恕。然而，世事幻变，出乎布利奥妮的预算。
