St. Clair River Habitat Improvements Likely Helping Fish

By on December 10, 2015

Nine fish habitat improvement projects in the St. Clair River look to be delivering on their goal of making conditions better for fish, according to The Times Herald of Port Huron, Michigan. Though researchers involved with the projects say that it’s too early to say so definitively.

Some of the fish that could benefit from the habitat enhancements stretching from Port Huron to Harsens Island include sturgeon, lake whitefish and lake trout. Scientists are especially concerned with native species like those that have spawned in the St. Clair River historically.

Evaluations to gauge the success of the habitat improvements are relying on checks for fish eggs and larvae as well as gauging the health of reefs restored in the river.

Organizations involved with the work include the U.S. Fish and Wildlife Service, Michigan Department of Natural Resources, Michigan Sea Grant and the Ontario Ministry of Natural Resources and Forestry. The U.S. Geological Survey is also assisting.
