摘要
2008年5月—2009年9月通过双船拖网采样,对山东北部沿海28个站位进行了调查,分析研究了该海域的幼鱼种类组成及优势种。调查结果表明,该海域共出现幼鱼75种,属14目41科65属,以底层鱼类为主要组成,占总种类数的78.67%;优势种有鳀鱼、方氏云鳚、玉筋鱼、黄鲫、蓝点马鲛、小黄鱼、矛尾刺鱼叚虎鱼等;幼鱼种类组成具有显著的季节变化,但年间变化较小。
From May 2008 to September 2009, twenty-eight stations were investigated from E 121^o1. 283＇ to 122^o44. 946＇,N37^o31. 7521 to 38^o15. 132＇ in the Northern coastal waters of Shandong province by twoboat trawling for four cruises. Species composition and the dominant species of the fish juveniles were analyzed in detail. The results showed that there were seventy-five species, sixty-five genera, forty-one families, fourteen orders. They were mainly bottom fish, 78.67% of the total number of species. The domi nant species were Engraulis japonicus , Enedrias f angi , Ammodytes personatus , Setipinna taty , Scomberomorus niphonius, Laramichthys polyactis, and Acanthogobius hasta. The seasonal changes in species composition of the juvenile fish were obvious in the Northern coastal waters of Shandong, but a little in years.
