Major Goals and Objectives

• Determine whether ruffe and gobies display overlap in use of habitat and food and thus may compete for benthic resources
• Determine whether zebra mussels will modify ruffe – goby interactions directly by serving as a major food resource for gobies or indirectly by increasing benthic heterogeneity and associated invertebrate production,
• Determine how yellow perch will respond to coexistence with ruffe and gobies in the presence or absence of zebra mussels
