摘要

为了研究黄海中部沿海生态系统渔业资源组成的季节变化及其与环境因子的相关性,采用虾梁拖网进行了渔业调查。利用对虾梁拖网在黄海中部沿海生态系统共采集到6个分类群57科81种的渔业资源。其中双壳纲6种,头足纲6种,甲壳纲22种,棘皮纲2种,腹足纲5种,双鱼纲40种。多样性指数(Shannon指数,H)呈季节性变化,冬季低值为2.14,春季高值为2.67。主要优势种为

Seasonal variation of fisheries resources composition in the coastal ecosystem of the middle Yellow Sea of Korea
To investigate seasonal variation of fisheries resources composition and their correlationships withenvironmental facotrs in the coastal ecosystem of the middle Yellow Sea of Korea, shrimp beam trawl werecarried out for the fisheries survey. Fisheries resources of 81 species, 57 families, and 6 taxa totally werecollected by shrimp beam trawl in the middle coastal ecosystem of Yellow Sea of Korea. Species were included6 species in Bivalvia, 6 in Cephalopoda, 22 in Crustacea, 2 in Echinodermata, 5 in Gastropoda, and 40 in Pisces.Diversity indices (Shannon index, H) showed seasonal variation with low value of 2.14 in winter, and highvalue of 2.67 in spring. Main dominant species were
