Abstract文章采用标志放流回捕方法评估了人工繁育鳜放流规格对其成活、生长和产量的影响。2012年5—6月选取3种不同大小规格的人工繁育鳜鱼苗各800尾,中等规格鳜苗种和大规格鳜苗种分别采用剪尾鳍和编码金属标标记后放入试验湖泊小赛湖,2012年12月试验湖泊逐渐降低水位,回捕收集放流鳜并鉴定身份。结果显示3种规格放流鳜的总成活率为40.5%,其中大规格放流鳜的成活率为63%,明显高于中规格放流鳜(39.1%)和小规格放流鳜(19.5%)。放流鳜的终末体长和体重均随放流规格的增加而增加,且3种规格放流鳜的终末体长和体重均呈现显著差异。放流鳜的产量和净收益在大规格处理组最大,在小规格处理组最小。结果表明鳜放流规格对鳜放流成功与否有重要影响,建议长江中游湖泊鳜的最佳放流规格应不小于50mm。
