我国近海鲚鱼生态习性及其产量变动状况

一、概述 鲚鱼是鲚属(Coilia)鱼类的泛称,属鲱形目(Clupeiformes),鳀科(Engraulidae)。我国有记录的共8种,除去同物异名或错误记载,目前大家一致承认的共4种,即:刀鲚(长頜鲚,Coilia ectenes Jordan et Seale)、凤鲚C.mystus(Linneaus)]、七絲鲚(C.grayii Richardson)和短頜鲚(C.brachygnathus Kreyenberg et Pappenheim)。刀鲚主要分布在我国黄渤海和东海一带。凡通海的江河如辽河、海河、黄河、长江、钱塘江等均能见到。凤鲚在我国海域分布十分广泛,北起

ECOLOGICAL HABITS AND DISTRIBUTION OF COILIA ALONG THE CHINESE COAST AND ITS CHANGES OF OUTPUT

This paper reports four species of Coilia: Coilia ectenes Jordon et Seale, C. mystus (Linneaus), C. grayii Richardson and C. brachygnathus kreyenberg et Pappenbeim. Areas of their mojor distribution are found to be at estuaries along the Chinese coast from Liaoning to Guangxi. Their ecological habits and characteristics, and changes of output are also reported. Lastly, protective measures of fisher resources are suggested by the authors.
