This manuscript evaluates the performance of numerous candidate metrics for lake fish assemblages in southern New England, comparing metric behavior with total phosphorus (as a measure of eutrophication stress) and a generalized measure of human activity in the watersheds (% of land in urban and agriculture, road and population density). This manuscript presents solutions to issues of species tolerances to stressors in lakes and to trophic guild membership. These modifications improved the performance of four candidate metrics (% individuals of highly tolerant species, % top carnivore individuals, % insectivorous individuals, % generalist feeder individuals). A total of seven metrics appear to be useful for evaluating biotic integirty of lakes in southern New England.
