In the news: After 25 years, Lake Michigan refuge fails to nurture wild lake trout

Posted August 31st, 2010 in Fisheries, News

From the Great Lakes Echo:

Any lake trout pulled from the wild blue waters of Lake Michigan now was probably born in a government building.

That’s despite a 45-year-old, multi-million-dollar program aimed at restoring a self-sustaining, naturally reproducing population of what was formerly the Great Lakes’ top predator.

Lake trout were wiped out in most of the Great Lakes by the mid-1900s as a result of overfishing, invasive species and habitat destruction. Managers started stocking them in Lake Michigan in 1965.

After little success, a 1985 revamp of the plan focused stocking on two relatively shallow, rocky sections of Lake Michigan where fishing for the species was banned.

At least part of that overhaul has proven fruitless, according to a study published recently in the North American Journal of Fisheries Management. Read more.

Coastal protection is not limited to concrete, rocks, and steel. Coastal protection solutions exist on a spectrum, ranging from softer “green” solutions to harder “gray” structures.

Nature-based coastal solutions fall between green and gray techniques, providing multiple benefits to people and habitats.

Our three-part video series, Nature-Based Coastal Solutions in the Great Lakes, is now available to watch. Learn how nature-based coastal solutions, including nature-driven and hybrid approaches, can protect shorelines while supporting ecosystems and communities.

Managers and researchers can be faced with a need to classify the risk of new crayfish invaders. Rapid assessment tools, such as the Science-based Tools for Assessing Invasion Risk (STAIR), can assist in this process by providing a streamlined framework for analysis and decision-making.

Join us for an ICC webinar with John Bieber from Loyola University Chicago to learn how rapid assessment tools are used to classify invasive species risk and how STAIR can support invasive crayfish management.
