East China Sea Yellow Sea Demersal fish Structure of community
根据1991年1~2月东、黄海冬季底层鱼类资源调查资料,分析了该海域的鱼类群落结构。本次调查共捕获鱼类4562.49kg,72935尾,198种。其中,暖温种居第1位,有87种,占43.9%;暖水种次之,有86种,占43.4%;冷温种最少,有15种,占7.6%。相对重要性指数(IRI)大于500的鱼类定为优势种,共有5种:竹荚鱼、带鱼、小黄鱼、鯷鱼、绿鳍马面鲀;IRI值在500~100的鱼类定为常见种,共有10种:银鲳、短尾大眼鲷、黑鳃梅童鱼、短鳍红娘鱼、黄鮟鱇、细纹狮子鱼、黑鮟鱇、龙头鱼、黄鲫、白姑鱼。使用种类丰富度指数(D)、Shannon-Wiener多样度指数(H′)、种类均匀度指数(J′)分析该海域鱼类群落多样性特征,D值变动在1.121~7.086之间,H′值在0.586~2.896之间,J′值在0.203~0.793之间。上述物种多样度指数均分别与水深、底层水温、底层盐度在α=0.01水平上,各自成显著正相关。
根據1991年1~2月東、黃海鼕季底層魚類資源調查資料,分析瞭該海域的魚類群落結構。本次調查共捕穫魚類4562.49kg,72935尾,198種。其中,暖溫種居第1位,有87種,佔43.9%;暖水種次之,有86種,佔43.4%;冷溫種最少,有15種,佔7.6%。相對重要性指數(IRI)大于500的魚類定為優勢種,共有5種:竹莢魚、帶魚、小黃魚、鯷魚、綠鰭馬麵鲀;IRI值在500~100的魚類定為常見種,共有10種:銀鯧、短尾大眼鯛、黑鰓梅童魚、短鰭紅孃魚、黃鮟鱇、細紋獅子魚、黑鮟鱇、龍頭魚、黃鯽、白姑魚。使用種類豐富度指數(D)、Shannon-Wiener多樣度指數(H′)、種類均勻度指數(J′)分析該海域魚類群落多樣性特徵,D值變動在1.121~7.086之間,H′值在0.586~2.896之間,J′值在0.203~0.793之間。上述物種多樣度指數均分彆與水深、底層水溫、底層鹽度在α=0.01水平上,各自成顯著正相關。

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).
