The river ecosystem plays an important role in the material energy cycle in nature and the survival and development of human beings. With the development of human social production and the increasing impact on the environment, the health of rivers has attracted global attention. The purpose of this paper is to evaluate the health status of large-scale aquaculture aquatic ecosystems based on the standardized method of fuzzy comprehensive biological index evaluation. Assessment of the health of aquaculture-type large aquatic ecosystems using the Bioindices method. The comparison of evaluation results shows that the waters P-IBI score calculated by the quadrant method is between 20-34, and the waters P-IBI score calculated by the third method is between 12-25. The situation is relatively consistent, so the quartile method is more suitable for evaluating the aquatic ecological health of aquaculture waters.
