光倒刺鲃网箱高产养殖研究

Research on the High-yielding Spininbabus hollandi Oshima Cultured in Cage

[目的]研究光倒刺鲃网箱养殖。[方法]在广西昭平县桂江、龙州县左江和南宁市郁江分别设置网箱养光倒刺鲃商品鱼。[结果]平均单产为76.65kg/m^2，投喂配合饲料，饵料系数4.12，养殖的经济效益以昭平六养殖户为例，单位面积利润为500～661元/m^2，瞬时生长率（gi）昭平为0.0669，龙州为0.1435，南宁为0.1338，前者生长速度显著缓慢与水温有关。[结论]昭平商品鱼质量最好，可能与水质有关。

[ Objective ] The Spininbabus hollandi Oshima, raised in cage, was researched. [ Method ] The site of the Spininbabus hollandi Oshima raised in cage was set up in Guijiang of Zhaoping County, Zuojiang of Longzhou County and Yujiang of Nanning city in Guangxi Province. [Result] The average yield of Spininbabus hollandi Oshima fed with compound feed was 76.6.5 kg/m^2. The coefficient of bait to feed was 4.12. The economic benefits of aquaculture of six farmers in Zhaoping, for example, was 500 to 661 yuan/m^2. The instantaneous growth rate（gi） Was 0. 066 9 in Zhaoping, 0. 143 5 in Longzhou and 0. 133 8 in Nanning and the slow growth rate of the former was significantly related to the water temperature. [ Conclusion] The fish products from Zhaoping had the best quality, which could be related to water quality.
