在水质肥沃的水库里,利用网箱进行不投饵培育鲢鳙鱼等鱼种,不仅切实可行,而且具有不占鱼种塘,不花鱼饲料,成本低等优点。在不投饵情况下,利用网箱在水库里培育一尾13cm左右的花白鲢鱼种,成本不到0.10元,而在池塘内培育同样大小的一尾鱼种的成本在0.10元以上;产量按亩折算,约合1 In the water quality fertile reservoirs, the use of cages do not bait breeding silver carp and bighead carp and other species, not only feasible, but also does not account for fish ponds, fish feed, low cost and so on. In the absence of feeding, the use of cages in the reservoir to cultivate about 13cm of the species of silver carp cost less than 0.10 yuan, and in the pond to cultivate the same size of a fish species cost more than 0.10 yuan; output Calculated by mu, about 1
