| 摘 要： | 2008-2011年对金沙江下游干流进行了6次鱼类资源调查,共设5个采样点,每次调查时间为1-2个月.共计采集到鱼类6目、16科、52属、78种,圆口铜鱼(Coreius guichenoti)、南方鲇(Silurus meridionalis)、鲤Cyprinus (Cyprinus)carpio]、瓦氏黄颡鱼(Pelteobagrus vachelli)、长鳍吻鮈(Rhinogobio ventralis)、餐(Hemiculter leucisculus)、鲇(Silurus asotus)、短须裂腹鱼Schizothorax(Schizothorax)wangchiachii]、蛇鮈(Saurogobio dabryi)和中华倒刺鲃(Spinibarbus sinensis)为金沙江下游渔获物主要种类,不同江段的渔获物组成存在差异.渔获物平均尾重达到50 g的种类仅13种,且多数种类的起捕规格小于10,部分甚至小于1.0g,渔获个体以1～3龄鱼为主,大部分未达到性成熟年龄,渔获物小型化、低龄化现象明显,鱼类资源呈衰退趋势.
