克氏原螯虾和鳜鱼池塘混养不同模式的比较

Comparison of Different Pond Polyculture Models of Procambarus clarkii and Siniperca chuatsi

[目的]筛选出适宜的克氏原螯虾、鳜鱼池塘混养模式。[方法]设置3种克氏原螯虾、鳜鱼投放比例,研究克氏原螯虾和鳜鱼的商品规格、产量、投入成本、利润、产出投入比等指标。[结果]3组商品克氏原螯虾规格从大到小依次为A、B、C组,商品鳜鱼规格从大到小依次为C、B、A组;A、B、C组平均成本分别为158 010.0、93 382.5、57 112.5元/hm^2;A、B、C组平均利润分别为101 749.1、61 550.6和37 273.4元/hm^2;A、B、C组产出投入比为1.61~1.73,各组差异不显著。[结论]B组模式投入成本和利润适中,养殖风险可控,可进行大面积推广应用。

[Objective] To screen out suitable pond polyculture model of Procambarus clarkii and Siniperca chuatsi. [Method]Three mixing ratios of P. clarkii and S. chuatsi were designed to study the commodity specification,output,input cost,profit,output-input ratio and other indices of P. clarkii and S. chuatsi. [Result]The commodity specification order of P. clarkii was group A group B group C and commodity specification order of S. chuatsi was group A group B group C. The average cost in group A,group B and group C were 158 010. 0,93 382. 5 and57 112. 5 Yuan/hm2 respectively. The average profit in group A,group B and group C were 101 749. 1,61 550. 6 and 37 273. 4 yuan/hm2 respectively. The output-input ratio in three groups was 1. 61-1. 73,but there was no significant difference. [Conclusion]The model in group B had moderate input cost and profit,controllable risks,so it could be widely applied.
