摘要:

根据2021年3月、5月、7月和8月福建闽江口及附近海域4个航次的拖网调查资料,研究分析了该海域鱼类群落的种类组成、数量分布、优势种及多样性特征。结果显示,调查海域共捕获鱼类104种,隶属于13目46科71属,其中鲈形目种类最多,有50种,鲱形目次之,有16种;暖水性鱼类占70.19%,底层、近底层鱼类合占69.23%;鱼类优势种有凤鲚( Coilia mystus )、二长棘鲷(Parargyrops edita)、斑鱼祭( Konosirus punctatus )等14种,多数鱼种仅是1~2航次的优势种,季节性差异明显;鱼类资源平均质量密度和数量密度分别为667.10 kg·km-2和71.91×103 ind·km-2,夏季明显高于春季;鱼类群落Shannon-Wiener多样性指数海区均值为2.622,处于较好水平。

Abstract:

Based on the data of fisheries resource survey by trawling from Minjiang Estuary and adjacent waters in Fujian in March,May,July,August in 2021,species composition,quantitative distribution,dominant species and community biodiversity characteristic of the fish were analyzed.Results showed that there were 104 kinds of fish in the investigated sea area,belonging 13 orders,46 families and 71 genera;among which the most species were Perciformes(50 kinds),followed by Clupeiformes(16 kinds).The temperature adaptability of fish was mainly warm water species,accounting for 70.19%,and the distributed water layer was mainly at the bottom species and the near-bottom species,accounting for 69.23% in total.There were 14 kinds of dominant species such as Coilia mystus,Parargyrops edita,Konosirus punctatus,and so on,most of them only occurring in 1 or 2 surveys,with significant seasonal differences.The fish stock density in weight and quantity were 667.10 kg·km-2 and 71.91×103 ind·km-2,respectively,which were higher in summer than spring.The Shannon-Wiener biodiversity index of fish in Minjiang Estuary was at a good level(2.622).
