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.

摘  要:
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.
