Abstract

Abstract: In this study, the relationship between fish assemblage structure and environmental factors was analyzed in a bay in southern Brazil. Fish were collected every two months between February and December 2002 at six sampling sites using bottom trawl nets. Abiotic data (salinity, temperature, rainfall, and depth) and biotic data (number of individuals, biomass, and total length of individuals from each species) were obtained. In total, 56 fish species representing 27 families were collected. Assemblage structure varied with seasonality, as was evidenced by the variation in temperature and rainfall in each season. Catches showed a high abundance of demersal fishes, particularly Genidens genidens, Eucinostomus gula, and E. argenteus.

巴西南部亚热带河口鱼类组合模式

摘要本研究分析了巴西南部某海湾鱼类群落结构与环境因子的关系。本署于2002年2月至12月期间，每两个月在六个取样地点用底拖网采集鱼类。获得了非生物数据(盐度、温度、降雨量和深度)和生物数据(每个物种的个体数、生物量和总长度)。共收集了27科56种鱼类。组合结构随季节变化而变化，各季节温度和降雨量的变化证明了这一点。渔获量显示底栖鱼类丰度较高，尤以Genidens Genidens、Eucinostomus gula和e.a genteus居多。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
