  abstract = {{R}apid anthropogenic nutrient enrichment has caused widespread ecological problems in aquatic ecosystems and the resulting eutrophication has dramatically changed fish communities throughout the world. {H}owever, few studies ad-dressed how fish communities responded to eutrophication in terms of multidimensional functional and taxonomic structure, especially how eutrophication acted as an environment filter on functional traits. {T}he aim of the present study was to investigate the effects of eutrophication on fish species composition, community metrics and species func-tional traits in 26 shallow lakes from the middle reaches of {Y}angtze {R}iver basin, {C}hina. {T}his study validated that eu-trophication is an important factor shaping the fish community structure. {R}egression analyses showed that eutrophication favored higher total biomass and lower functional diversity of fish communities but had little effect on species richness. {D}espite the fact that some pelagic zooplanktivorous species were more abundant in the most eu-trophic lakes, multivariate analyses of the relationships between species traits and environmental variables revealed weak relationships between feeding traits and eutrophication. {I}n contrast, species with a benthic life stage were neg-atively associated with eutrophication while those with a large body size and high absolute fecundity showed the op-posite trend. {D}ue to demersal habitat degradation, and to a lesser degree, to changes in trophic resources availability, eutrophication caused functional simplification of fish communities by increasing functional traits homogeneity among the most tolerant species. {S}ome relationships between functional traits and eutrophication well established in the western palearctic have not been observed in this study, emphasizing the importance of biases resulting from specific evolutionary histories. {T}his work will provide useful insights on on-going restoration and management of shal-low lakes in the {Y}angtze {R}iver basin.},
