双季对虾养殖是利用不同养殖种类的生态学和生物学特性差异,进行一年双季养殖。利用1976年南移到福建南部的中国对虾(Penaeus orientalis)的子代作为亲虾,经过越冬培育仔虾作为早季养殖的对象。以本地产的长毛对虾(P.penicillatns)为晚季养殖的种类,进行一年两季轮养。双季对虾养殖可在不增加人员、设备和基本建设投资的情况下,充分利用原有池塘的生产潜力,改变养殖方式及生产安排,达到提高单位面积产量,增加收入的目的。
Shuangji shrimp farming is the use of different types of aquaculture ecology and biological differences, a year of double breeding. The offspring of Penaeus orientalis, which moved south to southern Fujian Province in 1976, were used as broodstock to breed larvae through winter as subjects for early season breeding. Native species of P. penicillatns are cultivated for late-season farming and are reared in two seasons. Twinned shrimp farming can make full use of the production potential of existing ponds and change breeding methods and production arrangements without increasing personnel, equipment and capital construction investment so as to achieve the purpose of increasing output per unit area and increasing income.
