The feasibility of a potential bioindicator based on functional groups of microzooplankton tintinnids for bioassessments of water quality status was studied during southwest monsoon (June to September) along the coastal waters of Kalpakkam, India during 2012-2015. The work highlights the following features (1) tintinnid community composed of 28 species belonging to 11 genera and 9 families, revealed significant differences among the four study sites (2) maximum numerical abundance (2224±90ind. l) and species diversity (H'=2.66) of tintinnid were recorded towards Bay of Bengal whereas minimum abundance (720±35ind. l) and diversity (H'=1.74) were encountered in the backwater sites, (3) multivariate analyses [RELATE, Biota-environment (BIOENV) and canonical analysis of principal coordinates (CAP)] reveal that chl a, nitrate and phosphate were the potential causative factors for tintinnid distribution. Based on the results, we suggest that tintinnids may be used as a potential bioindicator of water quality status in marine ecosystem.
2012年至2015年西南季风期间（6月至9月），在印度卡尔帕卡姆沿海水域，研究了基于微型浮游动物铃虫功能群的潜在生物指标用于水质状况生物评估的可行性。该研究突出了以下特点：（1）铃虫群落由11属9科的28个物种组成，四个研究地点之间存在显著差异；（2）铃虫的最大数量丰度（2224±90个/升）和物种多样性（H'=2.66）出现在孟加拉湾，而在回水地点数量丰度最低（720±35个/升），多样性也最低（H'=1.74）；（3）多变量分析[RELATE、生物群-环境（BIOENV）和主坐标典型分析（CAP）]表明，叶绿素a、硝酸盐和磷酸盐是铃虫分布的潜在成因。基于这些结果，我们建议铃虫可作为海洋生态系统水质状况的潜在生物指标。
