Description of Work USGS will conduct monthly samples of benthic invertebrates, zooplankton, and water quality as well as seasonal sampling of fish and fish diets. This project supports lower trophic sampling in Lake Erie and understanding food webs. An emphasis will be collecting samples from a nearshore to offshore design.

This project addressed regional climate change effects on aquatic food webs in the Great Lakes. We sought insights by examining Lake Erie as a representative system with a high level of anthropogenic impacts, strong nutrient gradients, seasonal hypoxia, and spatial overlap of cold- and cool-water fish guilds. In Lake Erie and in large embayments throughout the Great Lakes basin, this situation is a concern for fishery managers, as climate change may exacerbate hypoxia and reduce habitat volume for some species. We examined fish community composition, fine-scale distribution, prey availability, diets, and biochemical tracers for dominant fishes from study areas with medium-high nutrient levels (mesotrophic, Fairport...
