Invasive gobies staking out new territory

An uninvited outsider is rapidly showing up in new freshwater territory in Wisconsin–and a recent scientific study indicates the increasing impact of the small fish.  Researchers at the University of Wisconsin Center for Limnology found the invasive round goby has increased 10-fold in some of the state’s lakes and rivers. In addition to the Great Lakes, the fish are now showing up in 175 miles of inland streams, according to Matthew Kornis, doctoral candidate at the Center for Limnology. Like many of the known invasive species inhibiting the Great Lakes, the round goby arrived by an ocean-bound ship and was first seen in the Saint Clair River in 1990. “The study,” Kornis says, “raises significant concern of negative effects round gobies will have or already have on Great Lakes tributaries.”

Researchers found a related dramatic decline in native fish in places where gobies thrive.

Michigan expands Great Lakes muskie stock

The muskie production program of the Department of Natural Resources (DNR) has turned a huge corner by stocking only Great Lakes muskies. The department has raised muskellunge for stocking for decades but had always used northern muskies. This is the second year it produced strictly Great Lakes muskies.

Are dead deer cash cows?

Haehnle Memorial Sanctuary sees Sandhill Cranes in record numbers

Sandhill cranes have been spotted in record numbers this year at the Phyllis Haehnle Memorial Audubon Sanctuary near Chelsea, Mich. The Michigan Audubon Society reported 8,177 cranes gathered in the sanctuary Monday, November 19, the most birds ever seen there since the 1900s. Once on the verge of extinction, sandhill crane populations have been on the rise across the United States for the past decade, according to Audubon Society spokesperson Mallory King. “They were almost extinct at the beginning of the 1900s, their feathers were in high demand and they were being overhunted,” King said, “That started to turn around as environmental legislation was passed starting in the 1930s and 40s, and now they’ve been steadily recovering.”

The birds return to their birthplace each year to find a mate. “We’re seeing so many birds here because the sanctuary has the right habitat for them and because enough of the cranes born here last year survived to return,” King said.
