While there are areas of Lake Erie known as dead zones, where there is not enough oxygen for fish to survive, the lake still contains a wide variety of fish. The location of the fish changes based on a number of factors including time of year, oxygen levels and pollution.
The types of fish in Lake Erie include walleye, perch, lake trout, small mouth bass, steel head and salmon. The dead zones, which are caused by an influx of nutrition from human and animal waste, cause plant life to multiply rapidly, making the area uninhabitable for fish and other animals. The location of the dead zones changes, and therefore the areas where fish can be found also changes.
