The principal result of this study was the establishment of an on-going long-term investigation of the spread of an exotic benthic fish species, the round goby in Lake Erie. The first gobies in Lake Erie were observed by Ohio EPA in 1993; the species now is found in all the Great Lakes . It is a benthic fish that can attain very high abundances in its preferred habitat of shallow-water, zebra-mussel dominated, hard-bottomed surfaces. The objective of this project was to document possible ecological impacts of the goby's invasion of hard-substrate, shallow-water benthic communities. The specific intent of this project was to develop methods for monitoring biotic changes within a set of study sites to be established in the lake's central basin during the summer of 1996, and to re-survey these sites in early spring of 1997.
