草鱼以其营养丰富,肉质鲜美,价格高、生长快,饲料来源广,赢得广大养殖户亲睐。但草鱼鱼种的供给却成为制约草鱼成鱼养殖发展的瓶颈,采用传统的方式培育草鱼鱼种产量低、病害多,大批量、大规模的优质鱼种很难得到。2012年我们进行池塘高密度培育草鱼鱼种试验,当年草鱼鱼种平均单产1150kg/667m2,套养花白鲢鱼种100kg/667m2,草鱼鱼种平均个体150g,取得了较好试验效果与经济效益,其技术总结如下:
Grass carp to its nutrient-rich, delicious meat, high prices, fast growth, wide source of feed, won the majority of farmers pro-Lai. However, the supply of grass carp fingerling has become a bottleneck that restricts the development of grass carp into adult fish. It is very difficult to obtain grass carp fingerlings with low yields, many diseases, large quantities and large-scale high-quality fingerlings. In 2012, we conducted the test of high-density cultivation of grass carp in ponds. In that year, the average yields of grass carp fingerlings were 1150kg / 667m 2, 100kg / 667m 2 for gardening silver carp and 150g for grass carp fingerlings respectively. Good experimental results and economic benefits were achieved. The technical summary is as follows:
