罗非鱼生长快、耐粗食、抗病力强,但在养殖过程中,由于其性成熟早、繁殖力强、繁殖周期短,导致种群密度大,严重影响商品鱼质量。为解决这一问题,我们在罗非鱼池套养加州鲈,控制罗非鱼子代数量,取得了较好效果。现将试验结果总结如下:1 材料与方法1.1 池塘条件 试验池塘 1 口,面
Tilapia grow fast, rough crude, disease resistance, but in the breeding process, because of its sexual maturity early, strong reproductive, short breeding cycle, resulting in population density, seriously affecting the quality of commercial fish. To solve this problem, we nest California bass in the tilapia pond and control the number of tilapia offspring, with good results. Now the test results are summarized as follows: 1 Materials and Methods 1.1 pond conditions test pond 1, noodles
