Abstract

Invasive species create multiple issues within an ecosystem. Disruption of food webs, degradation of habitats, and lower species diversity are just a few examples. The presence of Quagga and Zebra mussels, both invasive species, has contributed to a shift in bottom lake productivity in Lake Michigan. Because of this shift, the important predator-prey relationship between alewife (Alosa pseudoharengus) and Chinook salmon (Oncorhynchus tshawytscha) has been jeopardized. Alewife is another non-native species; however stable populations of this prey fish are crucial to supporting sustainable harvests of stocked and natural populations of Chinook salmon. The future success of a multi-million dollar sport fishery that has evolved from this predator-prey relationship is now threatened. A literature review of the Lake Michigan ecosystem will help to determine options for the future of charter fishing industries in Lake Michigan.
