In a Name?
(Pair-kop´-siss) from Greek meaning "perch-like"
Do They Live?
Trout-perch occur in all drainages of Minnesota. They are especially abundant in the Mississippi River (upper and lower), the St. Croix River, the Rainy River, and many of the state's clear, deep lakes, including Lake Superior. Trout-perch inhabit water that is clear to moderately turbid (cloudy) with bottoms of sand and gravel. They prefer the deeper areas of lakes and tend to stay away from the shallow, muddy areas.
Big Do They Get?
Do They Eat?
Trout-perch eat a variety of small aquatic animals including waterfleas, copepods, sideswimmers, fingernail clams, and midge larvae. Larval trout-perch eat rotifers, waterfleas, and copepods, while large adults occasionally go for a small minnow or darter.
