摘要
松江鲈为国家二级保护动物,历史上曾广泛分布于中国沿海及其邻近淡水水域。近数十年来,由于环境污染及人为因素,导致其在我国的分布区急剧缩小,种群数量逐渐下降。目前,仅在鸭绿江下游流域(辽宁省丹东市界内)有相当数量的种群分布。文章综述了近年来国内学者对鸭绿江下游流域松江鲈资源的研究状况。
Trachidermus fasciatus is a secondary protective animal of China. Historically, it distributed widely in the sea and coastal fresh water area of China. For environmental and human reasons, the distribution area of the fish has sharply narrowed in recent decades. Its population quantity has been reducing. Presently, there are only a definite number of Traehidermus fasciatus in the Yalu River downstream area. In this study, the research advance on resource of Traehidermus faseiatus in Yalu River downstream area in recent years is summarized.
