秋冬季节是亲鱼性腺发育的早期阶段,这个时期亲鱼培育的好坏将决定翌年春季人工繁殖的成败。因此,必须重视亲鱼秋冬季节的培育,其具体培育方法如下: 1、合理施肥。入冬前每亩池塘每周施腐熟肥500千克,其中鲢鱼池施人粪约占70％,畜粪约占30％;鳙鱼池以施牛粪为主,一般占70％,人粪占30％。入冬后遵循“少量多次,不断补充”的施肥原则,少量补 Autumn and winter are the early stages of broodstock gonadal development, broodstock breeding during this period will determine the success or failure of the artificial breeding the following spring. Therefore, we must attach importance to broodstock cultivation in autumn and winter, the specific cultivation methods are as follows: 1, a reasonable fertilization. Per mu pond before winter farming rotten fertilizer 500 kilograms per week, of which chub fish pond manure accounted for about 70% of livestock manure accounted for about 30%; catfish pond to manure-based, generally accounting for 70%, 30% of manure %. Follow winter after “a small number of times, constantly added” principle of fertilization, a small amount of make up
