摘    要:选择环境安静,水质清新,水面开阔的库湾设置网箱(2 a=10 mm)养殖牛蛙,放养体重50~100 g的牛蛙160~200只/m2,100 g以上的牛蛙80~100只/m2,探索解决牛蛙常规养殖存在的污染环境和疾病严重等问题。结果表明:牛蛙的成活率为94.3%,日均增重1.33~2.97 g,网箱新增产值178元/m2,显著高于牛蛙常规养殖和鱼塘网箱养殖效益,为牛蛙养殖和综合提高水体养殖效益提供新的发展途径。

关 键 词:牛蛙  膨化饲料  水库  网箱

Abstract:Frog(Rana catesbeiana) weighing both 50 to 100 g and over 100 g were stocked into cages with a mesh of 10 mm at a rate of 160 to 200 individuals/m~2 and 80 to 100 individuals /m~2 and fed floating feed in a quiet and wide reservoir,respectively.It was found that the frog had survival rate of 94.3%,and daily average weight increment of 1.33 to 2.97g.There was economic benefit of 178 RMB/m~2 in this culture pattern.
Keywords:Rana catesbeiana  floating feed  reservoir  cage
