• Each management unit covers the watersheds in their area - which includes the inland lakes, rivers and streams - in addition to the part of the Great Lakes that these drain into. Each unit has fisheries biologists and technicians that do research, conduct surveys, work with hatcheries to make stocking decisions, set fishing regulations, and work with their area research stations. All of this contributes to making sound decisions on how to manage Michigan’s fisheries in both the Great Lakes and the inland lakes, rivers and streams.
