综合养殖技术是江西万年县湖云塘水产场经历十多年探索,实践、完善的高效生态养殖模式。并连年取得珠鱼亩平年产值5000元以上的较好效益。琚经济核算,投入与产出比,一般为1:3,高达1:5。业已证明,综合养殖是发展高产,低耗、高效生态渔业的有效途径。现将综合养殖技术介绍如下。 一、池塘条件。综合养殖的池塘面积以10亩以上为好。池深2米左右。水源充足、水质无污染,进、排水方便,保水性能好、旱涝保收、光照时间长。 二、放养品种搭配与密度。每亩水面放养鱼种300—400尾,其中花、白鲢35％,草鳊鱼50％,鲤鲫为10％,其它鱼5％,但这—搭配比例,可因地制宜,灵活掌握。白鲢因与蚌争食,放养量稍加控制。吊养育珠蚌800—1000只,网箱底养小蚌3000只左右。
Comprehensive breeding technology is Wannian County, Jiangxi Yun pond aquatic field experienced more than 10 years to explore, practice and improve the efficient eco-farming model. And perennial Zhuzhou mu annual output of 5,000 yuan more than the better results.琚 economic accounting, input and output ratio, usually 1: 3, up to 1: 5. It has been proven that integrated aquaculture is an effective way to develop high-yield, low-consumption and highly efficient ecological fisheries. Integrated farming techniques are introduced below. First, the pond conditions. Integrated breeding pond area of 10 acres or more as well. Pool depth of 2 meters. Adequate water, water quality and pollution, into the drainage convenience, water retention, drought and flood protection, light a long time. Second, stocking varieties and density. 300-400 fish are stocked per mu of water, of which 35% are flowers, 50% silver carp, 50% grass carp, 10% carp crucian and 5% other fish. However, this proportion can be flexibly adjusted according to local conditions. Silver carp fight with mussels, stocking slightly controlled. Hanging pearl oyster 800-1000 only, at the end of the cage keeping clam 3000 or so.
