In a Name?
Do They Live?
Brown trout are not native to North America. They were introduced in the eastern USA in 1883 and probably into Minnesota not to long afterward. They were introduced into many of Minnesota's stream by 1923. Today, they occur in many of Minnesota's cold-water streams and lakes and also in Lake Superior. Some of these streams and lakes have reproducing populations in them. Others are restocked every few years. Brown trout can live in warmer and more turbid (cloudier) water than brook trout can. This allows them to live in the downstream portions of coldwater streams, while brook trout live in the headwaters. Brown trout frequently are found living with blacknosed dace, mottled sculpins, white suckers, creek chubs, common shiners, northern brook lampreys, and American brook lampreys.
Big Do They Get?
Do They Eat?
The brown trout is a very active feeder and it eats a great variety of foods. It commonly feeds upon land and water insects, zooplankton, worms, crayfish, small clams, snails, and a variety of small fish (young trout, sculpins, minnows, and darters). In a few strange cases, large browns have been known to eat young mink and small turtles.
