根据斑点叉尾(鱼回)亲鱼性腺发育情况不同季节的生态环境,配制不同营养水平的亲鱼配合饲料,分类放养,分期培育,有效提高了亲鱼成熟度。同时为了适应大规模繁育苗种的生产需要,不断完善繁育设施,改进繁育技术,使亲鱼繁殖期比当地提前30d,年繁殖鱼苗392万尾,推广2.5cm 以上鱼种220万尾,池存8cm 以上大规格鱼种150万尾,苗种收入573万元.
According to the ecological environment of catfish gonadal development in different seasons of Channel Catfish (FISH), the feed of broodstock with different nutrient levels was formulated to be sorted and stocked in stages, and the maturity of broodstock was effectively improved. At the same time, in order to meet the needs of large-scale breeding seed production, constantly improve the breeding facilities, improve breeding technology, the broodstock breeding period 30d earlier than the local, the annual breeding 392 million fish fry, promotion 2.5cm above species 2200000, pool storage 8cm More than 1.5 million large size fish species, seed income 5730000 yuan.
