摘要
根据2016-2017年间在三娘湾海域取得的渔获资源调查数据,对该海域渔获群落组成的月变化及多样性做了相关分析。结果表明,总渔获物有65种,以硬骨鱼纲为主,有62种,此外,聚类分析发现,鱼群结构组成有明显的月变化,但同一季节内的月份间的物种群落结构却又有较高的相似性,可能与同一季度内水温等因素变化不明显有关;各调查月份渔获的平均分类学差异指数(Δ+)都远小于理论平均值,在95%置信区间(P<0. 05)外,鱼类间的分类学距离近,分类差异变异指数(∧+)理论平均值为351,高于其它海域,显现出三娘湾海域鱼类组成的均匀度差,两个指数都表明该海域环境受人为活动干扰较严重。
The monthly variation and diversity of the fishing community in Sanniang Bay were analyzed based on the data of the fishing resources storey in the period from 2016 to 2017. The resuhs showed that there were 65 species of total catches, mainly Scleroderma and 62 species. In addition, clustering analysis showed that the composition of fish swarm had obvious monthly changes, hut the species community structure in the same season had a higher similarity, which might be related to the changes of water temperature and other factors in the same season. The average taxonomic difference index （ △＋） of fishing in each month was much smaller than the theoretical average In the 95% confidence interval （P〈0. 05 ） , the taxonomic distance between fish was close, the average value of the classification difference index （∧＋） theory was 351, which was higher than that of other sea areas, showing the difference of fish composition in Sanniang Bay. And both two indexes indicate that the environment of the sea area is seriously disturbed by human activities.
