摘　　要：半月湾是当地重要的渔业活动区域,近年来大型人类施工活动较为频繁,为了解该海域游泳动物的群落现状,于2019-2020年春秋两季在该海域进行调查,利用相对重要性指数、相对资源密度、物种多样性指数,数量生物量比较曲线等方法,对该海域游动动物的群落种类组成特点,及其群落结构的稳定性等方面进行分析。本次研究结果表明:此次调查共捕获4纲19目42科107种游泳动物,优势种多为小型鱼类及甲壳类;两季节多样性水平不高,种类组成小型化、低值化明显;秋季和春季的资源密度,与福建省其他海域相比,资源水平不高;ABC曲线分析显示,半月湾海域秋季和春季的群落结构均受到扰动,资源结构向小型化、低值化的饵料型种类转变。Banyue Bay is an important area for local fishery but the construction activities of human are increasingly frequent.In order to determine the current status of fishery resources in this area,based on the fixed-point survey data in Banyue Bay,Fujian,from November 2019 to March 2020,the index of realative importance,relative resource density,species diversity and Abundance Biomass Comparison were used to analyze the species composition and evaluate the stability of community structure.The results showed that a total of 107 species were captured involving 4 classes,19 orders,42 families,the most dominant species were small-sized fish and crustacea,while the diversity level of the autumn and spring was not high.The distribution of the species was obviously smallsized and low-valued.The resource densities were lower than other areas of the Fujian Province.The ABC curve showed that the community structure was disturbed to some extent in autumn and spring,and the species composition was small individual species with fast growth and low-valued.
