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。
Select a quiet environment, fresh water, Open Bank Bay set cage (2 a = 10 mm) Breeding bullfrog, stocking bullfrogs weighing 50 ~ 100 g 160 ~ 200 / m2, bullfrogs 100 g or more 80 ~ 100 / m2, explores and solves the problems of the polluted environment and the serious disease existing in the conventional breeding of bullfrogs. The results showed that the survival rate of bullfrogs was 94.3%, the daily average weight gain was 1.33-2.97 g, and the net output value of newly added cages was 178 yuan / m2, which was significantly higher than that of conventional bullfrog breeding and fish net cage culture. Water culture benefits provide a new way to develop.
