摘　　要：为探究池塘小网箱养殖马口鱼(Opsariichthys bidens Gunther)的效果,试验将塑胶渔排放置于池塘中部,使用聚乙烯网箱捆绑于塑胶渔排上,分3个网箱试验组(分别编号为M1、M2和M3),网箱规格为长2.0 m×宽2.0 m×深1.5 m。选择初始体重为(13.90±0.55)g马口鱼幼鱼,每个网箱平均投放360尾,投喂粗蛋白为41%的膨化配合饲料。通过66 d的网箱养殖后结果发现,3组网箱马口鱼的平均存活率为(70.88±4.83)%、特定生长率为(0.97±0.04)%·d^(-1)、饲料系数为(2.15±0.15),体重增长呈指数函数:y=11.563e^(0.212 5x)(R^(2)=0.987 9)。试验还观察到网箱养殖马口鱼的摄食与生长在水温26~30℃时表现最佳。To investigate the effect of small-scale cage aquaculture on Opsariichthys bidens Gunther in pond,the experiment placed plastic fishing rafts in the middle of the pond and tied cage to the polyethylene.They were divided into 3 groups(numbered M1,M2,and M3),with cage size of 2.0 m in length,2.0 m in width,and 1.5 m in depth.Each small-scale cage had 360 fish with initial body weight(13.90±0.55)g,and fed with a 41%crude protein puffed formula feed.After 66 days of small-scale cage culture,the results showed that the average survival rate were(70.88±4.83)%of 3 groups,the specific growth rate were(0.97±0.04)%·d^(-1),and the feed coefficient were(2.15±0.15).The body weight growth showed an exponential function:y=11.563e^(0.2125x)(R^(2)=0.9879).This experiment also observed that the feeding and growth of Opsariichthys bidens Gunther performed best when water temperatures were 26-30℃.
