The expansion of a spawning reef for lake sturgeon in the Detroit River is helping the fish population recover in the area, raising hopes for future efforts to improve the Great Lakes fishery, wildlife officials said.
The findings are from the U.S. Geological Survey and U.S. Fish and Wildlife Service about the Fighting Island reef expansion in Ontario, Canada. Officials used 2014 monitoring data to make their determination about the spawning reef in the river, which runs between the U.S. and Canada.
"Our data show that viable lake whitefish eggs were present on the expanded reef bed in the fall of 2013 and that walleye, lake sturgeon and native sucker eggs were also present there in the spring of 2014," Edward Roseman, a biologist with the Geological Survey's Great Lakes Science Center, said in a statement.
"We also found larval lake sturgeon downstream of the expanded reef, confirming that the reef is producing both lake sturgeon eggs and larvae."

The positive sample of Asian carp eDNA revealed earlier this month turned out to be the only one discovered in the Kalamazoo River.
The Department of Natural Resources (DNR) announced today all the follow-up samples taken from the river in reaction to the discovery came back negative.

Each year, the Detroit Free Press honors the state's Green Leaders — individuals, businesses and nonprofits setting the example with green practices that protect the environment by saving energy and recycling, among other efforts.

An increasing number of business owners and residents want be greener. They're recycling, insulating and buying more efficient appliances. They're counting kilowatts and cutting carbon emissions.

Less than 1% of Michigan's renewable energy is generated from solar power, and not every home is a candidate for it.
Still, more homeowners are making an investment in renewable energy, especially as prices for the equipment come down and their electricity bills edge up, according to utility companies and solar proponents. There's also a federal tax credit set to expire in 2016.
