东五里湖是太湖的子湖。位于无锡市南郊,面积5000余亩,常年水位较稳定。人工粗养鱼年亩产在40公斤左右。1984年在湖中选多块大小不等水域围栏养鱼,其中一块2.88亩的圆形水域进行精养试验,当年亩产达1354.5公斤,净亩产1024公斤。1985年继续进行高产试养小平均亩产1635.85公斤。现将外荡围栏精养鱼创高产的主要技术措施和经验介绍于下:
East Wuli Lake is a lake in Taihu Lake. Located in the southern suburbs of Wuxi City, an area of 5,000 acres, perennial water level is more stable. Artificial crude fish annual yield of 40 kg. In 1984, a large number of fenced-fish farms of various sizes were selected in the lake. Among them, a 2.88-mu circular water area was intensively tested. In that year, the mu production reached 1354.5 kilograms and that of the net mu produce of 1024 kilograms. In 1985 continue to carry out high yield test small average yield of 1635.85 kilograms. The main technical measures and experience of high-yielding fish farms fencing intensive fish will be introduced in the next:
