First record of Corophium mucronatum sars (Crustacea: Amphipoda) in the Great Lakes
Journal of Great Lakes Research
Corophium mucronatum Sars, a small amphipod native to the Caspian and Black Sea basins, was discovered in September 1997 in Lake St. Clair. A single individual was collected using a bottom sled dredge in littoral waters adjacent to Seaway Island, Ontario. The specimen was found on silty-sand substrate in an area populated by submerged macrophytes. Because no other Corophium individuals were found despite repeated sampling over two years at a total of 60 sites in the corridor between the St. Clair River and western Lake Erie, it is highly unlikely that this species has established in the Great Lakes.
