Abstract

Background: The estimated biodiversity indices showed spatial and temporal variations in the biodiversity of finfish and shellfish among the three stations of Ennore Creek, from September 2018 to August 2019 and from September 2022 to August 2023 at fortnightly intervals. Methods: A total of three sampling sites (S1, S2 and S3) were chosen in Ennore Creek for the present research. Occurrence data of finfish and shellfish species caught using gill nets were collected at the three selected sites of Ennore Creek. PRIMER v7 (Plymouth Routines in Multivariate Ecological Research), a statistical software tool created at the Plymouth Marine Laboratory in the United Kingdom (Clarke and Gorley, 2006) was used. Result: The findings showed that within the study area, there were more species, higher abundances, larger individuals and a higher percentage of Least Concern (77.6%), Not Evaluated (16.3%) and Data Deficient (6.1%). For every species of shellfish that has been documented, the IUCN classification is 100% not evaluated. But there are very few species of shellfish and finfish. Significant variations in fish abundance were found when the mean abundance of vulnerable, endangered and least concerned species for the assessed, unprotected areas were analysed.

印度泰米尔纳德邦恩诺尔溪各种鱼类的生物多样性和丰度

背景：估算的生物多样性指数显示，2018 年 9 月至 2019 年 8 月和 2022 年 9 月至 2023 年 8 月期间，恩诺尔溪三个站点的有鳍鱼类和贝类生物多样性每两周出现一次时空变化。采样方法本研究在 Ennore 溪共选择了三个采样点（S1、S2 和 S3）。在 Ennore 溪的三个选定地点收集了使用刺网捕获的有鳍鱼类和贝类的出现数据。使用了英国普利茅斯海洋实验室开发的统计软件工具 PRIMER v7（普利茅斯多变量生态研究常规）（Clarke 和 Gorley，2006 年）。结果研究结果表明，在研究区域内，贝类的种类较多、丰度较高、个体较大，且极少关注（77.6%）、未评估（16.3%）和数据不足（6.1%）的比例较高。对于每一种有记录的贝类，世界自然保护联盟的分类都是 100% 未评估。但贝类和鳍鱼的种类很少。在对评估的非保护区中的易危、濒危和最不关注物种的平均数量进行分析时，发现鱼类数量存在显著差异。
