材料与方法: 为适应热带生产而修正的测试程序:为保证实验条件下获得的结果在热带商业性养殖生产中的有效性,必须修改试验程序(见表1)。为了避免重复交配,简化交配过程。减少繁殖用设施,实验鱼必须是经过鉴定后确认是全同胞的鱼。此外,成功交配率的检测可减少到每周1次。进行全同胞孵化时,将3—7日龄的鱼苗全部放于实验用孵化缸中。为简化孵化过程, MATERIALS AND METHODS: TEST PROCEDURES CORRECTED TO TROPICAL PRODUCTION: In order to ensure that the results obtained under experimental conditions are valid in tropical commercial breeding production, the test procedure must be modified (see Table 1). In order to avoid duplication of mating, to simplify the mating process. Reduce reproductive facilities, experimental fish must be identified after identification is the sibling fish. In addition, the detection of successful mating rate can be reduced to once a week. For full sibling hatching, all fry from 3 to 7 days of age are placed in a laboratory incubator. To simplify the incubation process,
