摘要
在水库中设置规格为 2× 2× 2 m3 的双层聚乙烯网箱养殖草鱼 ,按 4.1kg/ m3 投放鱼种 181尾 ,共重16.5 kg.饲养 12 5天 ,养成商品鱼 168尾 ,成活率达 92 .8% ,鱼产量 13 2 .65 kg,净增长 116.15 kg,饲料系数 2 .11.
In this experiment,doublenet cage(2×2×2m 3) made of polyethylene was used for grass carp culturing in the reservoirs.As fish density of 4.1 kg/m 3,total weight 16.5kg,181 grass carp were cultured in the net cage.After stocking feed for 125 days, we gained 168 grass carp, the total weight of which was 132.65 kg.The survival rate of fish was 92.8% and the net weight of fish growth was 116.15kg.The feed conversion was 2.11.
