Great Lakes Migrants: More Than Just Salmon
The fall salmon run is a powerful reminder that backyard creeks and streams are connected to the Great Lakes. Salmon are one of many fish that move between habitat types. Great Lakes anglers often use the term anadromous to describe the salmon's upstream movement into Great Lakes tributaries, but the term potamodromous is a more accurate description of fish behavior that involves moving between freshwater environments over the course of the life cycle.

Many of Michigan's 15 species of sucker are also potamodromous. Although suckers do not necessarily die after spawning as Pacific salmon do, they can still play an important role in transferring nutrients upstream during their spring spawning run.
