为了探索斑点叉尾鱼回无公害健康养殖模式,提高鱼回鱼养殖技术,促进峡江县鱼回鱼产业化发展,我们于2 0 0 4年在江西省峡江县鱼种场利用美国大豆协会80 :2 0池塘养殖模式和全植物性蛋白豆粕型膨化浮性饲料进行了斑点叉尾鱼回夏花养至鱼种的示范试验,取得了良好的试验效果。三口试验池塘中斑点叉尾鱼回经过10 9d饲养后平均体重从1.0 7g长到38.81g。鱼的总产量为16 15 .4kg ,平均成活率为86 .8%。三口池塘饲料的平均系数为0 .96 ,净收入为16 46 .0 5元/亩,投资回报率平均为6 2 .3%。试验结果表明,设计合理的养殖模式,采用优质饲料,是实现健康养殖,获得良好经济效益的关键。
In order to explore the mode of feeding healthy skipjack fish back to pollution-free and to improve the technology of fish back to fish culture and to promote the industrialization of fish back to fish in Xiajiang County, we used American soybeans in 2004 in Xiajiang County, Jiangxi Province Association 80: 20 pond culture model and all-plant protein soybean meal extruded puffed feed for the shantou fish back to the summer to fish species demonstration test and achieved good results. In the three experimental ponds, the average body weight of the Picchu backcross after 10 9 days of feeding was 1.07g to 38.81g. The total fish production was 16 15.4 kg, with an average survival rate of 86.8%. The average coefficient of feed for three ponds was 0.96 and the net income was 16 46.05 yuan / mu, with an average return on investment of 62.3%. The test results show that the rational design of farming patterns, the use of high-quality feed, is to achieve healthy farming, access to good economic benefits of the key.
