Dr. John Dettmers with the Great Lakes Fisheries Commission Recently published an article about sport fish in the Great Lakes called “Whether to Manage for Economics or the Ecosystem?”. I reached out to Dr. Dettmers to be a guest on The Blue Fish Radio Show as it was clear he held another important piece of the Great Lakes fisheries puzzle. In short, what is the role,history, status and future of prey fish , mainly Alewife, Smelt and Cisco, and what does this mean for the salmon and other sportfish?

Link below to hear Dr. John Dettmers on this episode of Blue Fish Radio:

The Great Lakes Fishery Commission was established in 1955 by the Canadian/U.S. Convention on Great Lakes Fisheries. The commission coordinates fisheries research, controls the invasive sea lamprey, and facilitates cooperative fishery management among the state, provincial, tribal, and federal agencies.
