1979至1983年连续五年,我所与市属有关县进行了当年常规鱼苗养成食用鱼试验,总面积达239.5亩。试验结果表明,当年鱼苗养成食用鱼,充分发挥了鱼的生长优势,缩短养殖周期1～2年,成本降低,经济效益显著提高。现将1981～1983年我所试验中的4口池塘结果报告如下。每口池塘1.0～6.6亩,总共12亩。池形规则,池底较平坦、淤 For five consecutive years from 1979 to 1983, I conducted a pilot experiment with fish fry for fish breeding in that year in a county-level county with a total area of ​​239.5 mu. The test results showed that when the fishes were raised into food fish, the fish’s growth advantages were fully exerted, the breeding cycle was shortened by 1 to 2 years, the cost was reduced, and the economic benefits were significantly increased. The results of the four ponds I tested in 1981-1983 are as follows. Each pond 1.0 ~ 6.6 acres, a total of 12 acres. Pool rules, the pool floor is more flat, silt
