摘　　要：Poyang Lake catfish （Silurus asotus Linnaeus） is native to Poyang Lake Basin. Artificial propagation of Poyang Lake catfish was carried out by using artificial insemination. Under water temperature of 18-26 ℃, embryonic development of Poyang Lake catfish in impounded water was observed and recorded in detail. Embryonic development of Poyang Lake catfish encountered seven stages, and it last- ed for 47.08 h from the fertilized egg stage to the stripping stage. The hatching time of Silurus meridionalis Chen was shortest, followed by that of Poyang Lake catfish, and the hatching time of Pelteobagrus vachelli was longest.鄱阳湖土鲶（Silimsa sotus Lirlnaeus）是江西省鄱阳湖流域本地鲶鱼。采用人工授精方式进行鄱阳湖土鲶人工繁殖．在18℃。26℃的水温条件下对鄱阳湖土鲶胚胎静止水体中发育过程进行了详细的观察记录，胚胎发育经过7个时期，从受精卵到孵化出膜约为47．08h。并将观察结果与南方大口鲶、瓦氏黄颡鱼静止水体胚胎发育时间进行了比较。对比发现南方大口鲶孵化时间最短，其次为鄱阳湖土鲶．用时最长的为瓦氏黄颡鱼。
