在现有池塘中,浅水塘仍占有很大比重。这类池塘水浅,排灌不配套,有的是季节性积水成塘,养殖传统鱼类,产量低、效益不佳。为了探讨这类池塘增产、增收、增效的途径,1995～1997年连续3年,我们进行了浅水塘主养淡水白鲳的试验示范与大面积推广,取得了满意的效果,平均亩产白鲳416公斤,最大个体1.1公斤,最小个体0.45公斤,亩产值高达5000元,经济效益和社会效益极佳。现将浅水塘主养淡水白鲳
Among the existing ponds, shallow reservoirs still account for a large proportion. Such shallow ponds, irrigated irrigation is not complete, and some seasonal stagnant ponds, breeding of traditional fish, low yield, poor efficiency. In order to explore the ways of increasing production, increasing income and increasing efficiency of such ponds, for three consecutive years from 1995 to 1997, we carried out pilot demonstration and large-scale popularization of main freshwater pomfret in shallow ponds and achieved satisfactory results. The average yield per mu鲳 416 kg, the largest individual 1.1 kg, the smallest individual 0.45 kg, mu output value up to 5,000 yuan, excellent economic and social benefits. The main shallow pond now freshwater bream
