Abstract

This study was designed to explore the habitat characteristics and dispersal of the round goby (Neogobius melanostomus), an exotic fish in the Great Lakes. Three surveys using SCUBA, trawls and seines were conducted in the western basin of Lake Erie to identify assemblages of fishes before and after the appearance of round gobies. Round gobies were not present in the surveys conducted during 1995, however 54 round gobies were caught in trawls in 1996, and were visible at Colchester Reef and Middle Sister Island during the SCUBA survey. Round gobies were separated in space from an assemblage of pelagic fishes. Line transects with use of SCUBA were conducted at 3 sites along the Huron/Erie corridor to examine habitat preference in day and night by round gobies. Mark-recapture (dye injection) and observational SCUBA studies were used to determine site affinity and home range of the round goby in the Detroit River. I anticipate that round gobies will disperse throughout the Great Lakes. (Abstract shortened by UMI.)Dept. of Biological Sciences.
