随着渔业生产的发展和群众对水产品消费水平的提高,改革池塘养殖品种结构,增加优质鱼的养殖已成为水产生产上的中心课题。我场自1983年起开始进行池塘养殖品种结构的改革,利用配合颗粒饲料养鱼的试验,并取得了初步的成效。在此基础上,我们在省、市、郊水产部门的支持下,继续进行了不同颗粒饲料配方及其养鱼效果的比较研究,旨在寻求既能提高优质鱼的比重,又能取得最佳经济效益的合理的饲料配方。现将试验结果总结如下。试验方法 1、池塘条件:试验在我场渔科站进行,选用科一和科五两个池塘,面积均为0.8亩,水深为1.5米左右。投放鱼种前进行池塘消毒。池塘水质良好,定期冲注新
With the development of fishery production and the masses raising the level of consumption of aquatic products, reforming the structure of pond aquaculture species and increasing the breeding of high-quality fish has become a central issue in aquatic products production. Since 1983, the field began to reform the structure of pond aquaculture species, using the experiment of fish farming with pellet feed, and achieved initial results. On this basis, with the support of the provincial, municipal and suburban aquatic products departments, we conducted a comparative study on different pellet formulations and fish culture effects, aiming to seek ways to increase both the proportion of premium fish and the best Economical and reasonable feed formula. The test results are summarized below. Test methods 1, the pond conditions: test fishing field in my field station, the selection of Branch 1 and Section 5 ponds, both an area of 0.8 acres and a depth of about 1.5 meters. Serve ponds before disinfection. Pond water quality, regular red new injection
