精养蟹池,若因饵料不足,发生弱肉强食现象,就会影响河蟹产量;但若投饵过多,河蟹吃剩饵料在水中又无法清除,既增加养殖成本,又会败坏水质。现根据我所几年来的实践经验,介绍一种简便的检测蟹池投饵量的方法,供各养蟹户参考。检测前备一个或几个罾(虾罾或特制皆可),在检测当日下午4—5时在罾上放一定量的河蟹饵料,将罾放进被检测水里。当日该蟹池饵料、投饵总量和投饵位置与前日相同,待第2
If you feed too much crab pool, if the phenomenon of insufficient feed, the phenomenon of law of the jungle will affect the production of crab; however, if you feed too much crab, you will not be able to clear the eaten bait in the water, which will increase the cost of breeding and spoil the water quality.
