黄颡鱼高效益养殖模式探讨

Study on the high-efficiency breeding mode of Pelteobagrus fulvidraco

【目的】研究利用水泥池高密度养殖两广地区特色淡水养殖品种黄颡鱼的养殖模式,为养殖户因地制宜开展黄顙鱼养殖提供技术指导。【方法】从广东地区引进规格为2.5g-3.5g/尾全雄黄颡鱼苗3万尾,分别在三口面积同为72m^2的内循环水泥池中养殖,对其养殖密度、饲料选择、投喂方式、水质调控、病害防控、生长性能等因素进行研究,从而总结出适合的养殖模式。【结果】内循环水泥池中高密度饲养黄颡鱼,养殖周期7个月,72m^2单池产量超过1100kg,与传统池塘养殖黄颡鱼的667m^2产量相近(1200kg/667m^2),个体平均规格超过150g,养殖成活率90%以上。【结论】内循环水泥池高密度饲养黄颡鱼,可以提高养殖效益和商品鱼质量。

【Objective】This paper studies the breeding model of Pelteobagrus fulvidraco,which is one of the characteristic in provinces of Guangxi and Guangdong,applying high density culture of cement pond,and provides technical guidance for farmers to develop Pelteobagrus fulvidraco culture according to local conditions.【Method】Thirty thousand full-male Pelteobagrus fulvidraco larvae of 2.5g-3.5g were intro⁃duced from Guangdong area and cultured in three ponds of 72m^2 with circulatory system.In order to find a suitable breeding model,the factors such as breeding density,feed selection and feeding mode,water quali⁃ty control,disease control and growth performance were studied.【Result】After seven months of breeding Pelteobagrus fulvidraco with circulatory system,cement pond can produce more than 1100kg per 72m^2 pond,which is similar to the yield of 667m2 raised in a traditional pond(1200kg/667m^2),and the average size is more than 150g,the survival rate is more than 90%.【Conclusion】High-density rearing of Pelteo⁃bagrus fulvidraco with internal circulation system can significantly improve the breeding efficiency and the quality of commercial fish.
