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.钱明无视两个少年的怒目侧视，继续不怕死地说道：所以你俩就不要折腾了：这扒了衣裳坦胸露肉的，让人瞧着就跟花楼的卖笑姑娘似的。可是，回到过去，即使再努力，也无法改变已经发生的事。的确，谁都没想到的是，赵文华突发雅兴，竟亲自掏腰包买了几串风铃。上车后掏出小葱那张处方细看了一遍，对那明显不是毛笔写出来的字好奇不已，又回想起刚才那小丫头说的话，忽地嘴角一勾，哼了一声。言下之意，都怪陈老爷。[Traffic] Take 803, 5 and 14 to Quanzhou Forest Park Station.
