湖泊养殖,单产总难以提高,一个重要原因,就是水面大、不好管理,基本是天放天养、人放天养。“千湖之省”的湖北,全省三百万亩湖水面,1983年,平均单产6公斤,1984年,平均单产10公斤。湖北省国营刁汉养殖场,在有关专家的指导下,根据网箱养鱼的原理,创造了“竹帘围养”的新方法,为提高湖泊养殖产量闯出了新路。 Lake breeding, total yield is difficult to increase, an important reason is that the water is big, not good management, the basic is to raise the sky, the day of human nature. Hubei Province, a province of thousands of lakes, has three million mu of lake water in the province. In 1983, the average yield was 6 kilograms. In 1984, the average yield was 10 kilograms. Hubei State-run Diaohan Farm, under the guidance of relevant experts, has created a new method of “bamboo curtain enclosure” according to the principle of fish cage culture, opening up a new road for raising the production of lakes.
