根据1997-2000年东海底拖网渔业资源调食资料,分析了东海红娘鱼属却Lepidorigla的种类组成和分布特征。调查中共出现了7种:翼红娘鱼、贡氏红娘鱼、深海红娘鱼、岸上红娘鱼、日本红娘鱼、短鳍红娘伍和斑鳍红娘鱼,其中深海红娘值、贡氏红娘鱼和短鳍红娘鱼为优势种类。7种红娘鱼主要分布于50-190 m水深范围内,利用聚类分析的方法分析发现其分布可分为两种类型:110 m以浅和110 m以深海域,相似性分析(ANOSIM)表明这两个海域红娘鱼属组成存在明显的差异。分布于110 m以浅海域的种类以翼红娘鱼和岸上红娘鱼为主,平均分布水深为87.9 m和103.1 m;.分布于110 m以深海域的种类以深海红娘鱼、短鳍红娘鱼、贡氏红娘鱼和日本红娘鱼为主,它们的平均分布水深为138.3 m、130.5 m、132.1 m和128.5 m。此外,还运用单因素方差分析方法(ANOVA)检验红娘鱼属各种类间底层水温和底层盐度非生物环境因子之间的差异显著性。
Based on the data of the regulation of trawl fishery resources in the East China Sea from 1997 to 2000, the species composition and distribution characteristics of Lepidorigla were analyzed. There were 7 species of wingfish, such as red-bonito, gongs, red-boned fish, red-spotted fish on the shore, Japanese bridal fish, redfinch and finned redfish, Matchfish is the dominant species. Seven species of Mythimna separata distribute mainly in the depth of 50-190 m. According to the cluster analysis method, the distribution of them can be divided into two types: 110 m shallow and 110 m deep, and the similarity analysis (ANOSIM) There is a clear difference in the composition of Myrtaceous genus in a sea area. The species distributed in the shallow sea area of 110 m were mainly dominated by wing red bridle and shore bridal fish with the average depths of 87.9 m and 103.1 m. The species distributed in the depth of 110 m were mainly composed of red sea turtle, Red-boned fish and Japanese red-spotted fish, their average depth of distribution of 138.3 m, 130.5 m, 132.1 m and 128.5 m. In addition, one-way analysis of variance (ANOVA) was also used to test the significance of the difference between the bottom water temperature of Salvia and the abiotic salinity of the bottom salinity.
