EVALUATION OF AQUATIC ENVIRONMENTAL QUALITY WITH SARCODINA AND CILIATED PROTOZOAN COMMUNITIES IN THE

This work sought to augment the community structure information of aquatic protozoa and analyse the aquatic environmental health of the Yongjiang River in order to provide a reference for ecological studies on medium and small rivers around the world. At 13 sampling sections, the structure characteristics and seasonal changes of the sarcodina and ciliated protozoan population were investigated and analysed. The findings revealed that there were 21 sarcodina species and 64 ciliate species, with significant differences between protozoan species at sample sections. The sarcodina and ciliated community's maximum diversity index H' was less than 2.3. The level of community similarity between portions was lower. The protozoan community contamination levels ranged from 2.131 to 2.238. It showed that the Yongjiang River was significantly contaminated. Environmental factors may boost the abundance of sarcodina and ciliated protozoa, according to a rebundancy analysis. The results of previous investigations utilising different aquatic biological indicators were consistent with the results of the protozoan biological index.
