蓝点马鲛网箱养殖试验报告

在国内首次进行了蓝点马鲛网箱养殖试验。对网箱结构，苗种兼捕，苗种放养，饵料投喂，鱼病防治等整套技术进行了研究。７２ｍ＾２网箱共养养成商品鱼１５５１尾，成活率５５％，平均尾重５８０ｇ，饵料系数７．２，单位面积产量１２．５ｋｇ／ｍ＾２。专家鉴定认为，本研究填补了国内空白，达国内领先水平。

Experiment on Culture of Carcharhinus glaucus Linnaeus in Net Cage

It is the first time to conduct an experiment on the culture of the mackerel(C. glaucus) with a net cage. A complete set of techniques such as the structure of the netcage,catching of the juvenile mackerels for stocking,feeding with diets and controlling fishdisease, etc. were studied. 1551 commercial fish were produced out of the net cage with thearea 0f m2,survival rate 55%,the average body weight 580 g per individual. The feed coefficient was 7. 2. The per unit yield was 12-5 kg per m2. The result,appralsed by experts,filledin the gaps at home and reached in the lead in the field of science and technology of the fishculture in net cage.
