| 摘 要： | 斑点叉尾是重要的经济养殖鱼类,本文从斑点叉尾亲鱼年龄、放养密度、产卵槽类型、饲料类型、池塘局部气候条件、池塘底质类型等方面对影响斑点叉尾自然产卵的关键因素进行了研究。结果表明,挑选4～5龄的亲鱼,在冬季气温、水温适当偏低的山区风口处建培育池,培育池底质为黏土硬底质或鹅卵石带沙底质,每667 m^2放亲鱼10～30组,全部投喂动物性饲料,用特制的土瓦罐作产卵槽,获得较高的自然产卵率。

| Abstract: | Related factors on natural spawning rate of Channel Catfish were been studied,including natural spawning in different parent fish ages,stocking densities,spawning tank type,feed type,local climatic and pond sediment type.Results showed that when the parent fish were in age 4-5,the broodstock ponds that the sediment were stiff clay or cobble and sandy clay were built at the ventilation of mountain area in winter,and the animals fed with the spanwning tank which made by special soil jar were 10-30 groups of per 667 m^2,the higher natural spawning rate would be achieved with 100% animal feed. |
