我县地处洞庭湖滨,水产资源丰富。目前利用湖河面积84806亩,占全县已利用养殖水面的43.5％。据1974—1984年水产年报统计,湖河年均鲜鱼产量3057.6吨,单产18公斤,只占全县年均总产量的27.2％。为了更好的挖掘生产潜力,提高经济效益,1986年我们在牛鼻滩区选择“两湖一河”,面积1666亩,开展了湖、可精养试验,现将试验情况报告如下: 一、材料与方法 1、湖、河生态条件:试验基地定在姚家垱(1000亩)、邹家湖(500亩)、冯氏港(河沟166亩)。三者系半封闭性调蓄湖、河;集雨面积分别为湖河的13倍、12倍、8倍;多雨季节,平均水深分
My county is located in Dongting Lake, rich aquatic resources. At present, the lake area of 84806 acres, accounting for 43.5% of the county has used aquaculture water. According to the annual report of aquaculture in 1974-1984, the annual average fresh fish production of Lake is 3,057.6 tons, yielding 18 kilograms, accounting for only 27.2% of the county’s total annual output. In 1986, we selected “Two Rivers and One River” in Niuntan area with an area of 1666 mu to carry out lake and intensive experiments to better tap the potential of production and increase economic benefits. The report of the test is as follows: I. Materials and Method 1. Ecological Conditions of Lakes and Rivers: The test base is set at Yaojiaba (1000 mu), Zoujianhu (500 mu) and Feng’s Harbor (166 mu). The three are semi-closed regulation lake, river; catchment area respectively 13 times the lake, 12 times, 8 times; rainy season, the average depth
