黄颡鱼广泛分布于长江中下游河流湖泊中,近年来,由于种苗短缺,黄颡鱼的总产量没有多大提高,故开展黄颡鱼人工繁殖与苗种培育的研究,对于水产养殖结构调整和农业产业化经营具有重要的现实意义。 一、亲鱼的选择与培育 2000年12月我们从繁殖点附近湖泊和干塘的成鱼池塘中收集、挑选黄颡鱼亲鱼820组,其中雌鱼在75g～100g、雄鱼在125g～150g之间。放入池塘中进行专池培育。在培育过程中套养少量的花白鲢,投喂部分野杂鱼和小虾,并配制了蛋白含量为40％左右的
Catfish are widely distributed in rivers and lakes in the middle and lower reaches of the Yangtze River. In recent years, due to the shortage of seedlings, the total output of catfish is not greatly improved. Therefore, the study on the artificial propagation and seed breeding of catfish is of great significance to aquaculture structural adjustment And the industrialization of agriculture has important practical significance. First, the selection and breeding of broodstock In December 2000 we collected from the ponds near the breeding ponds and ponds collected 820 species of broodstock, including the female in 75g ~ 100g, male in 125g ~ 150g between. Into the pond for training special pool. In the process of nurturing a small amount of flower silver carp, feeding some wild fish and shrimp, and the preparation of the protein content of about 40%
