Potential new cormorant management plan released

The U.S. Fish and Wildlife Service has released its proposed new plan to address double-crested cormorant conflicts and allow killing as many as 77,000 of the migratory birds in the Mississippi and Central flyways each year. In Michigan and 23 other states. The federally protected waterbird has historically created problems for shoreline communities, and critics blame them for destroying vegetation and declining fish populations in some places, such as the Les Cheneaux Islands and Mackinac County’s Brevoort Lake. A DNR expert calls the proposal a step in the right direction “even if it is not at the level of control that fisheries managers desire.” By Peter Payette & Cassidy Hough.

Bigheaded carp pose big threat, new model suggests

Bigheaded carp are a big threat to yellow perch, according to a new model that forecasts what would happen over the next several decades if bighead and silver carp made it into Lake Huron’s Saginaw Bay. The biggest concern is disruption of the food web. We hear from the National Oceanic and Atmospheric Administration, Michigan State, Cooperative Institute for Great Lakes Research and U.S. Fish & Wildlife Service. By Carin Tunney.

Study finds health risk from Pine River fish

A recent study finds a risk that anglers in the Pine RIver may become sickened by the bacteria E. coli from agricultural runoff. Researchers are from Alma College and the University of Toronto.

There’s a new kind of carp in the river and it’s huge

We talk to DNR, MUCC and Trout Unlimited. For news and outdoors sections.
