摘 要:
根据2004年5月和10月在青岛近海进行的渔业资源底拖网调查,对该海域渔业资源群落结构特征进行了初步研究.结果表明,春、秋季2个航次在该海域共捕获渔业资源种类76种.春、秋季单位网次渔获量分别为12.9kg/h和6.1kg/h,优势种类主要为赤鼻棱NB023（Thrissa kammalensis）、大泷六线鱼（Hexagrammos otakii）以及口虾蛄（Oratosquilla oratoria）、日本枪乌贼（Loligo japonica）等无脊椎动物.分别计算了青岛近海春、秋季渔业生物群落的种类丰度指数（R）、多样性指数（H′）和均匀度（J′）.聚类分析、单因子相似性分析（ANOSIM）以及相似性百分比分析（SIMPER）表明该水域渔业资源群落结构存在一定程度的时空异质性.青岛近海渔业资源呈现出明显的小型化和低质化特征.[著者文摘]

Abstract:
Based on the bottom trawl surveys in the coastal waters of Oingdao in May and Octomber, 2004, the community structure of fishery resources was preliminarily analyzed. The results indicated that there was 76 species collected from the bottom trawl surveys. The mean catch rates was 12.9kg/h and 6. 1kg/h in spring and autumn, respectively. The dominant species were red-nose anchovy Thrissa karnrnalensis, fat greenling Hexagrarnrnos otakii, and some invertebrates including Oratosquilla oratoria and Loligo japonica. The species richness R, Shannon diversity index H＇ and evenness index J＇ were calculated for the community of fishery resources in spring and autumn, respectively. Cluster analysis, analysis of similarity （ANOSIM） and similarity of percentage （SIMPER） showed that there existed to some extent spatiotemporal heterogeneity for the community structure of fishery resources in the coastal waters. The fishery resources species were characterized by minimization and low values.
Key words:
