Potential Impacts of Invading Ruffe (Gymnocephalus cernuus) on Benthic and Pelagic Ecosystems of the Great Lakes
Major Goals and Objectives
Our three major objectives are to determine:
- The potential competitive interactions between exotic
Eurasian ruffe and native yellow perch in Lake Michigan and throughout the Great Lakes, through new knowledge of their preferences for prey and habitat.
- How predators (e.g., pike) and another exotic animal, zebra mussels, might affect the success of ruffe and their interactions with yellow perch in the Great Lakes.
- The current composition of benthic macroinvertebrates in Lake Michigan to generate a baseline prior to the anticipated invasion by ruffe.
