摘　　要：为探讨河蟹生长特点以及渔获物与放养规格的关系 ,用有序样品的Fish聚类分析法首次对中华绒螯蟹的渔获物组成进行分析。结果显示 ,黄河三角洲广南水库沉砂池 2 0 0 0年河蟹渔获物可以分为 3个群体 ,与其放养的 3个不同规格群体相对应 ;据此推算了不同放养规格的回捕率 ;并对雌、雄生长和性成熟的差异以及合理的放养规格进行了探讨。This paper deals with the analysis on catches of Eriocheir sinensis (Chinese mitten crab) based on Fisher's clustering method for sequence data. The results indicated that there were about three groups in ~Eriocheir sinensis catches of Guangnan Reservoir in the Yellow River Delta in 2000, which was in accordance with the three artificial stocked crabs. The recapture rate of different size of stocked crabs, difference of growth and mature by female and male, and reasonable size of the stocked crab were also discussed.
