Changes in the bottom fauna of western Lake Erie Changes in the bottom fauna of western Lake Erie

The bottom fauna of western Lake Erie has changed dramatically over the past 50 years in response to environmental degradation and biological invasions. In 1953, low dissolved oxygen reduced the biodiversity of that fauna, especially burrowing mayflies and freshwater mussels (Unionidae). Canada and the United States signed the Great Lakes Water Quality Agreement in 1972. By 1982, over 7...

Consumption of rainbow smelt by walleye and salmonine fishes in eastern Lake Erie Consumption of rainbow smelt by walleye and salmonine fishes in eastern Lake Erie

At present, rainbow smelt appear to represent a key component of the eastern Lake Erie fish community as they are the dominant prey for virtually every open water predator, and are harvested directly by an important Ontario commercial fishery. In response to concern over the status of rainbow smelt in eastern Lake Erie, our objective was to quantify some primary top down forces of...
