上海地区低盐海水中斑节对虾养殖试验

Culture of Penaeus monodon Fabricius in Brackish water Pond of Shanghai Region

本试验共进行了两年。除88—2池跑苗外,试验组成活率达30%,产量均达到150公斤/亩左右,其中88—1池最高,为226.8公斤/亩。斑节对虾日生长率超过0.90毫米,与对照的中国对虾比,成活率、生长速度均高于对照组。在密度相近的条件下,生长速度快于中国对虾20%以上;饵料系数低于中国对虾,产量可达到或超过中国对虾产量,而生长期却缩短20天左右。试验结果说明,斑节对虾在上海地区养殖是完全可行的。

Pond culture test of Penaeus monodon was conducted in Shanghai for twe years. The survival rate of the shrimp was around 30% except that of one pond. The mean output was about 150kg/mu, and the highest was 226.8 kg/mu. The growth rato was all over 0.9 mm per day.Compared to the controls (Penaeus orientalis), both survival and growth rates of P. monodon were higher, however, the food conversion ratio was lower. The yield per unit area of P. monodon could reach or surpass that of P. orientalis cultured in Shanghai and its fattening cycle could be shortened by 20 days. The result illustrates that it is technically feasible to culture P. monodon in shangai region.
