摘要
为了探讨在重庆地区池塘使用膨化配合饲料主养鳙(Aristichthys nobilis)的可行性,研究选取了初始体重为(185.40±3.63)g的鳙 7406 尾和初始体重为(115.40±3.47)g的鲢(Hypophthalmichthys molitrix)1 955 尾,进行了为期近 19 个月的养殖试验.结果显示,鳙的增重率为(1 329.86±26.84)%,存活率为 90%;鲢的增重率为(2 021.00±75.45)%,存活率为 80%;亩利润为 3 273.59 元.这表明使用膨化配合饲料投喂可以提高鳙的生长性能和经济效益.研究结果可为池塘主养鳙模式的推广和应用提供理论依据.
Abstract
This paper mainly discussed the feasibility of using expanded compound feed to raise Aristichthys nobilis in ponds in Chongqing.In this study,7 406 Aristichthys nobilis with an initial body weight of(185.40±3.63)g and 1955 Hypophthalmichthys molitrix with an initial body weight of(115.40±3.47)g were selected for culture ex-periments for nearly 19 months.The results showed that the weight gain rate of Aristichthys nobilis was(1 329.86±26.84)%and the survival rate was 90%.The weight gain rate of Hypophthalmichthys molitrix was(2021.00±75.45)%,and the survival rate was 80%.The profit of yield per mu was 3 273.59 yuan.These results indicated that the growth performance and economic benefit of Aristichthys nobilis could be improved by using expanded com-pound feed.The paper also discussed the biological characteristics,breeding mode,feed requirements of bighead carp and the influence of pond main bighead carp on market and fishery structure adjustment.The results can pro-vide a theoretical basis for the popularization and application of the Aristichthys nobilis model in ponds.
