Ciliated protozoa have many advantages in bioassessment of water quality. The ability of tintinnids for assessing water quality status was studied during a 7-yearcycle in Jiaozhou Bay of the Yellow Sea, northern China. The samples were collected monthly at four sites with a spatial gradient of environmental pollution. Environmental variables, e.g., temperature, salinity, chlorophyll a (Chl a), dissolved inorganic nitrogen, soluble reactive phosphate (SRP), and soluble active silicate (SRSi), were measured synchronously for comparison with biotic parameters. Results showed that: (1) tintinnid community structures represented significant differences among the four sampling sites; (2) spatial patterns of the tintinnid communities were significantly correlated with environmental variables, especially SRSi and nutrients; and (3) the community structural parameters and the five dominant species were significantly correlated with SRSi and nutrients. We suggested that tintinnids may be used as a potential bioindicator for discriminating water quality status in marine ecosystems.
纤毛虫在水质生物评估方面具有诸多优势。在中国北方黄海胶州湾进行的为期7年的周期研究中，对铃壳虫评估水质状况的能力进行了研究。每月在四个具有环境污染空间梯度的站点采集样本。同步测量环境变量，如温度、盐度、叶绿素a（Chl a）、溶解无机氮、可溶性活性磷酸盐（SRP）和可溶性活性硅酸盐（SRSi），以便与生物参数进行比较。结果表明：（1）四个采样站点的铃壳虫群落结构存在显著差异；（2）铃壳虫群落的空间格局与环境变量显著相关，尤其是SRSi和营养物质；（3）群落结构参数和五个优势物种与SRSi和营养物质显著相关。我们认为铃壳虫可作为区分海洋生态系统水质状况的潜在生物指标。
