配合饲料与活饵料鱼养鳜效益比较

Comparative study on the benefits of mandarin fish(Siniperca chuatsi)culture with compound feed and mandarin fish culture in live bait fish

[目的]探索配合饲料替代活饵料鱼养鳜,节约活饵料鱼配套池塘养殖面积和活饵鱼资源,降低活饵料鱼养殖的饲料投喂和水体排放对生态环境的污染。[方法]采取对比新兴配合饲料与传统活饵料鱼养鳜这2种不同的养殖方式,通过记录2种养殖方式的投入、产量及产值,分析比较其经济效益。[结果]活饵料鱼养鳜投入与产出比为1∶(1.33~1.88),配合饲料养鳜投入与产出比为1∶(2.28~2.39);配合饲料养鳜效益是活饵料鱼养鳜效益的1.33~3.39倍。[结论]配合饲料养鳜的经济效益、生态效益显著优于活饵料鱼养鳜。

[Objectives]To explore the replacement of live bait fish with compound feed for mandarin fish cultivation,which could save the culture area and resources of live bait fish,as well as reduce the ecological environment pollution caused by feed feeding and water discharge of live bait fish culture.[Methods]To compare the two different farming methods of the new compound feed feeding and the traditional live bait fish feeding model.The economic benefits were analyzed and compared by recording the input,output and output value of the two farming methods.[Results]The input to output ratio of mandarin fish cultured with live bait fish was 1∶(1.33~1.88),while was 1∶(2.28~2.39)for mandarin fish cultured with compound feed.The benefit of mandarin fish cultured with compound feed feeding was 1.33~3.39times that of live bait fish feeding.[Conclusions]The economic and ecological benefits of mandarin fish farming with compound feed are significantly better than those of live bait fish mandarin farming.
