Muskegon and White lakes reach cleanup milestones

Cleanup efforts at two Michigan Areas of Concern, Muskegon Lake and White Lake, have reached important milestones, according to the Michigan Office of the Great Lakes. The Environmental Protection Agency on Feb. 26 lifted Beneficial Use Impairments on both lakes pertaining to fish consumption, allowing local residents and anglers to fish these lakes with fewer restrictions. Recent studies by Grand Valley State University on the lakes revealed that fish there did not possess higher concentrations of PCBs or mercury than fish in lakes that were not listed as Areas of Concern. Both lakes remain subject to the same fish consumption advisories as the other lakes in the area.

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.

New St. Clair River reefs to spur sturgeon spawning

Alright, sturgeon … they made your bed, now spawn in it.

Michigan organizations and agencies are building nine rock reefs in the Middle Channel of the St. Clair River to bolster native fish spawning and restore habitat.

Sex, water and rock and roll: Sturgeon spawn while singing on the rocks

How does a scientist use sound to save a 150-million-year-old fish? In Wisconsin, Ron Bruch and Chris Bocast are trying to help restore sturgeon stock by listening for the sound they make when spawning that some call “thunder.” The sound can be heard here. “It’s a real low frequency, you can almost feel it instead of hear it,” said Bruch, fish supervisor with the Wisconsin Department of Natural Resources. “One of the important measures of success is knowing your stock is spawning.”

Bocast, a University of Wisconsin-Madison doctoral student in acoustic ecology, discovered the sound while working on an audio book about sturgeons.

Great Lakes eels are a conservation challenge

Something slithers beneath the surface of the Great Lakes and it’s not a sea lamprey.

It might look similar, but the mysterious American eel isn’t a sucker.

And it’s in trouble. Its population is decreasing dramatically and no one is sure why.
