| 摘 要： | 斑点叉尾鮰(Ictalurus punctatus)繁育亲鱼筛选可量参数:体长为头长的3.88~4.17倍、体长为体高的4.59~5.26倍、体长为尾柄长的5.73~6.73倍、体长为尾柄高的11.05~11.95倍、尾柄长为尾柄高的1.78~1.94倍。亲鱼培育产卵池塘适宜面积为0.20~0.53hm2,单位面积池塘内亲鱼承载量为2400~2550kg/hm2,3~6龄亲鱼放养密度为375~450组/hm2。投喂亲鱼饵料以含蛋白质36%人工配合饵料与动物性饲料相结合。亲鱼培育池塘水体昼夜变化的溶氧量为4.0mg/L以上、pH值为6.8~7.6、氨氮小于0.3mg/L、亚硝酸盐为0.01mg/L以下,亲鱼产卵率为80%以上。
