Invasion of the other perch
The Herald-Palladium (8/21)
Michigan has another perch that is becoming increasingly more common. A native of the Atlantic Coast, where it exists in both salt and freshwater, the white perch invaded the Great Lakes in 1950 through the Erie Canal. It is now established in all five Great Lakes, reaching Lake Michigan in 1988.

Perch poised for revival in Lake Michigan
The Holland Sentinel (5/17)
Great Lakes fish biologists hope that after years of decline, 2008 will bring a significant rebound in the lakesí beleaguered yellow perch population.

White Perch found in Chequamegon
Duluth News Tribune (7/25)
Ice fishing in Chequamegon Bay last winter, Travis Nye of Ashland hooked a white perch -- the first one officially documented in the bay -- and set a new state record, too.

Anglers warned not to spread white perch into Winnebago
Milwaukee Journal Sentinel (9/23)
Wisconsin anglers must be more aware of what they're catching and releasing in Lake Winnebago so they don't introduce invasive species - which is what happened in the Fox River, state biologists say.

Invasive fish moves up Fox River
Green Bay Press-Gazette (9/19)
For the first time, white perch, an invasive species implicated in the decline of the yellow perch fishery in the Great Lakes and the bay of Green Bay, have been found in the Fox River upstream of the Rapide Croche navigational lock and dam northeast of Kaukauna, Wis.
