山东半岛南部近岸海域渔业资源群落结构的季节变化
Seasonal Variation on Community Structure of Fishery Resources in the Coastal Waters of Southern Shandong Peninsular
摘要
Abstract
Based on the bottom trawl surveys in the coastal waters of Southern Shandong Peninsular during summer and winter in 2006, spring and autumn in 2007, the community structure of fishery resources was analyzed preliminarily. Survey results indicated that there were 72 species. The mean catch rates in summer, winter, spring and autumn were 18.1, 6.9, 1.3 and 10. 3 kg/h, respectively. The seasonal variation of biomass in weight followed the order of summer>winter >autumn>spring. The dominant species were Thryssa kammalensis, Saurida elongate, Rachypenaeus curvirostris and some invertebrates including Oratosquilla oratoria, Loligo edulis and Rachypenaeus curvirostris etc. Based on the survey data, the species richness R, Shannon-Weiner diversity index H' and evenness index J' were calculated respectively. Cluster analysis, analysis of similarity (ANOSIM) and similarity of percentage (SIMPER) showed that fishery resources in this area were decreased compared with original data. The study provided a scientific basis on protection of fishery biology diversities and resources restoration in the coastal waters of Southern Shandong Peninsular.关键词
