Abstract: The Huangpu River is a multifunctional plain tidal river connecting the Taihu Lake and the Yangtze River Estuary, which flows through all central area of Shanghai city. Its main stream is 113.4 km long. From ecological perspective, this article used biotic integrity index of fish (F-IBI) to evaluate the water pollution and health impact of Huangpu River. Fish samples were collected from 7 sampling sites in the Huangpu River from November 2013 to July 2014. Large net cage, three layers of drift net and bottom trawl were used by the same effort. Totally 8816 fishes were caught. These fish were classified into 6 orders and 12 families, mostly 2 families and 24 species belonging to Cypriniformes. Next were the Perciformes and Siluriformes, which have 7 species nd 4 species respectively. According to dipartite degree and correlation analysis, the F-IBI evaluation system was established with 9 indicators. The evaluation results showed that the water ecological system of the Huangpu River was good in upper section, fair in the middle and poor in the lower section. The evaluation results also indicated that owing to the poor state of Xietang section which connected to the Taihu Lake water, the water ecological system of Songpu Bridge was poor or fair state. As Songpu Bridge area provides about thirty percent water for Shanghai, protection the water quality of the Dianshan Lake and the Taihu Lake is the key to ensure the water source security of the Huangpu River upstream. Moreover, in order to improve ecosystem situation of the middle and lower reaches, comprehensive water ecological restoration measures are required.

Key words: fish species diversity, biotic integrity index, ecosystem, health assessment, Huangpu River in Shanghai
