Reseachers were able to show off the first success of a project Tuesday August 28th to restore spawning habitat in the St. Clair River’s Middle Channel for lake sturgeon and other native fish. Workers in the spring built about an acre of rock reef in the river near Algonac. On Tuesday, researchers marked the early success of the project with the Huron-Erie Corridor Restoration Celebration along the city’s waterfront.

The search for Asian carp in Lake Erie has moved to the Sandusky River and Sandusky Bay, where 20 of 150 water samples collected in early August tested positive for the presence of silver carp environmental DNA, or eDNA.

Samples were also taken from the Maumee River, Maumee Bay and Western Lake Erie. The results of those samples should be available in September.

Lake Superior State University says its researchers are at work this summer trying to aid the survival of an endangered bird species, the piping plover.

The Department of Natural Resources has announced a tentative plan for stocking cuts to Lake Michigan trout and salmon. According to the tentative plan, chinook stocking would be reduced 38% in Wisconsin,  67% in Michigan, 8% in Illinois and 11% in Indiana. 

There was no sign of Asian carp in the waters that spill from southeastern Monroe County into Lake Erie, as was also the case during previous days of an electrofishing and netting survey that began Monday in Ohio. Roger Knight, the Lake Erie program administrator for the Ohio Department of Natural Resources' Division of Wildlife, wasn't surprised. He observed Wednesday's work from a nearby boat in North Maumee Bay. "I didn't expect that we would find one," Knight said. "If there were detectable numbers of these fish, we would have heard about them."

Technology usually used in oceans will be planted in Lake Superior by University of Minnesota Duluth researchers. During the winter months they will be able to detect things like temperature, depth, currents, light intensity and amount of oxygen

The spiny water flea, a tiny shrimp-like organism native to Europe and Asia, was discovered in a canal that connects Lake Champlain to the Hudson River, and then a fisherman found it in Lake George, an Adirondack lake located about a half-mile upstream from Lake Champlain.

The reason for the drop appears as clear as the lake's water on this tranquil evening: As invasive species have altered the Lake Michigan food web, the population of perch has plummeted. With fewer perch and restrictive regulations to protect the remaining population, anglers have either stopped fishing or are pursuing other species.erch have suffered from too many years of extremely poor recruitment, or survival of young fish, since the early 1990s.

The New York State Department of Environmental Conservation (DEC) has adopted some new freshwater fishing regulations, the DEC announced this week.

The changes to the current regulations will take effect starting Oct. 1, and will be in place through 2014.

All ideas are welcome at a public brainstorming session from 2 p.m. to 6 p.m. Aug. 20 at the Ganges Township Hall, 1904 64th Street, Fennville.
