东、黄海冬季底层鱼类群落结构及其多样性
THE STRUCTURE AND DIVERSITY OF DEMERSAL FISH COMMUNITIES IN WINTER IN THE EAST CHINA SEA AND THE YELLOW SEA
摘要
Abstract
Studies on the characteristics of fish communities structure and diversity are conducted, based on data from bottom trawl surveys during January～February 1991 in the East China Sea and the Yellow Sea. A total catch of 4 562.49 kg, 72 935 individuals comprising 198 species of fishes are composed of warm-temperate（43.9%），and warm-water（43.4%）and cold-temperate（7.6%）species.The species of fish with index of relative importance（IRI）over 500 is defined as dominant species, a total of 5 species that are Trachurus japonicus、Trichiurus haumala、Pseudosciaena polyactis、Engraulis japonicus、Navodon septentrionalis. The fish with IRI values of 100 to 500 is considered as common species, a total of 10 species which are Priacanthus macracanthus，Priacanthus macracanthus，Collichthys niveatus，Lepidotrigla microptera，Lophius litulon，Liparis tanakai，Lophiomus setigerus，Harpadon nehereus，Setipinna taty，Argyrosomus argentatus. Three diversity indexes which are species richness index（D）, Shannon-Wiener index（H′）, species evenness index（J′）are used to analyze the characteristics of species diversity of the fish communities. The value of D、H' and J' vary between 1.121～7.086，0.586～2.896 and 0.203～0.793 respectively.The three indexes are correlated respectively with water depth, water temperature and salinity of the bottom in positive significantly（P＜0.01）.关键词
