摘　　要：在湖北荆门地区面积5.3 hm^2的2口池塘,实施3~5 cm/尾、4 500尾/hm^2、150~200 g/尾3种规格鳙鱼池塘嵌套循环养殖技术研究。结果表明,以滤食性鳙鱼为主,混养搭配草食性鱼类、杂食性鱼类和凶猛肉食性鱼类;供试池塘投喂蛋白质含量30%的鳙鱼微颗粒饲料,结合投施少量生物肥培育池塘中的天然饵料,在7月前捕捞销售商品鳙鱼。2口供试池塘平均产量分别为15 105、15 435 kg/hm^2,鳙鱼产量占比均超过70%;养殖经济效益分别为81 525.70、82 649.90元/hm^2,投入产出比均达到1∶2.40以上。In the two ponds with an area of 5.3 hm^2 in the Jingmen area of Hubei, three kinds of carp pond nesting culture techniques were carried out in 3~5 cm/tail, 4 500 tail/hm^2, 150~200 g/tail. The results showed that the filter-eating carp was mainly mixed with herbivorous fish, omnivorous fish and ferocious carnivorous fish. The test pond was fed with 30% protein squid micro-grain feed, combined with a small amount of investment. The bio-fertilizer cultivates the natural bait in the pond and catches the commercial squid before July. The average yield of the two test ponds was 15 105 and 15 435 kg/hm^2 respectively, and the yield of carp was more than 70%;the economic benefits of breeding were 81 525.70 and 82 649.90 yuan/hm^2 respectively, and the input-output ratio reached 1∶2.40 the above.
