【摘要】 根据2009年5月和2011年5月在套子湾及其邻近海域进行的渔业资源底拖网调查资料,对该海域游泳动物群落结构进行了初步分析。结果表明,在该海域共捕获游泳动物67种,隶属于15目41科61属。两年间游泳动物平均相对资源量分别为12.9kg/h和8.7kg/h。日本褐虾(Crangon hakodatei)、方氏锦鳚(Pholis fangi)和日本鼓虾(Alpheus japonicus)在两年均为优势种。2011年调查海域种类丰富度(D)、多样性指数(H’)、均匀度指数(J’)均值略高于2009年,但ANOVA分析表明,2年间无显著差异(P>0.05)。数量生物量比较曲线(ABC曲线)分析表明,该海域渔业资源群落处于严重干扰专状态。聚类分析、单因子相似性分析(ANOSIM)、相似性百分比分析(SIMPER)、Jaccard种类相似性指数分析表明,调查海域游泳动物群落两年间存在一定差异。本研究可为套子湾及其邻近海域渔业生物多样性保护和资源管理提供参考依据。更多还原

【Abstract】 Based on the bottom trawl surveys in Taozi Bay and its adjacent waters in May, 2009 and May, 2011, the community structure of nekton species was analyzed preliminarily. Survey results indicated that there were 67 species in the two years. The mean catch rates in the two years were 12.92Kg/h and 8.70Kg/h, respectively. The common dominant species in the two years were Crangon hakodatei, Pholis fangi, and Alpheus japonicas. The species richness D, Shannon-Weiner diversity index H′and evenness index J′were calculated respectively. Cluster analysis, analysis of similarity (ANOSIM), similarity of percentage(SIMPER), Jaccard index analysis and abundance biomass comparison curve showed that fishery resources in this area were decreased. The study provided a scientific basis on protection of fishery biology diversities and resources restoration in Taozi Bay and its adjacent waters.更多还原
