| 摘 要： | 根据1997—2000年东海底拖网渔业资源调查资料，分析了东海红娘鱼属Lepidorigla的种类组成和分布特征。调查中共出现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、短鳍红娘鱼和斑鳍红娘鱼，其中深海红娘鱼、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50～190m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：110m以浅和110m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110m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87．9m和103．1m；分布于110m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138．3m、130．5m、132．1m和128．5m。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。

| Abstract: | Based on the data of bottom trawling fisheries resources survey in the East China Sea during 1997 and 2000, the species composition and distribution of the genus Lepidorigla were analyzed. 7 Lepidorigla species were caught during the survey, which were L. alata , L.abyssalis , L. micropterus , L. kishinouyi,L. guentheri , L. japomca and L. punctipectoralis . The dominant species were L. abyssalis, L. guentheri, L. micropterus. The genus Lepidorigla inhabits between 50 and 90 m depth. By using cluster analysis, the two distribution styles of the Lepidorigla species were identified, which were the less than 110m group and the more than 110 m group. The species compositions of the two groups were quite different by the ANOSIM (analysis of the similarity) test. The L.alata and L. kishinouyi were the dominant species in the less than 110 m group, whose average depth were 87.9 m and 103.1 m respectively. The L. abyssclis, L. micropterus,L. guentheri and L. japomca were the dominant species in the more than 110 m group, whose average depth were 138.3 m, 130.5 m,132.1 m and 128.5 m respectively. Furthermore the relationships between species distribution and environmental variables such as bottom temperature and bottom salinity were examined. |
