The Laurentian Great Lakes (LGL) formed following the retreat of Wisconsin glaciation 15-9 ka and provided a vast volume freshwater habitat for coregonines, which included diverse endemic complex ciscoes. However, anthropogenic impacts in 19th 20th centuries resulted declines losses ciscoes, leaving only Lake Superior with relatively intact that still dominates its prey fish community. In 1920s, W. Koelz described six putative cisco species from Superior: Coregonus artedi, C. hoyi, kiyi,...
The restoration of the once abundant Cisco ( Coregonus artedi ) is a management interest across Laurentian Great Lakes. To inform restoration, we (1) described historical distributions and (2) explored whether non-indigenous Rainbow Smelt Osmerus mordax Alewife Alosa pseudoharengus played role in decline populations upper Lakes (i.e., Superior, Michigan, Huron). Our source data were collected from fishery-independent surveys conducted by U.S. Fish Wildlife Service’s research vessel R/V...
