放养密度对胡子鲇池塘集约化养殖效益的影响

目的]确定池塘集约化单独饲养胡子鲇的最佳放养密度。方法]胡子鲇以放养密度20、30和40尾/m2放养于3口池塘中,150 d后分别比较3口塘中胡子鲇的单位面积产量、生产成本、利润和投入产出比。结果]放养密度为30尾/m2时,成本投入的效益转化率最高,养殖利润最大,利润达18.52元/m2,集约化养殖胡子鲇的放养密度以30尾/m2为宜。结论]胡子鲇的最佳放养密度为30尾/m2。

Effect of Stocking Density on Benefit of Clarias fuscus Intensive Culture

Objective] The purpose of this research was to prove up the best stocking density of intensive culture for separating in ponds. Method] Clarias fuscus were cultured by different stocking density which were 20,30 and 40 ind/m2. The yield per unit area,production cost,profit and input-output ratio of three ponds were compared respectively after 150 days.Result] The benefit conversion efficiency and cultured interest rate were the optimum,and the culture interest were reached 18.52 yuan/m2 when stocking density was 30 ind/m2. Conclusion] The best stocking density of Clarias fuscus was 30 ind/m2.
