Fish in Lake Superior Streams
The number and variety fishes that may be found in the stream
or river near your house may surprise you. Most, of course,
are not game fish. Fish communities change from one area to
another because of such factors as water temperature, water
velocity and clarity, alkalinity, and available habitat. Across
the US for instance, a typical Pacific mountain stream may
contain the fry and smolts of salmonids (trout and salmon),
sculpins (fishes of the Family Cottidae), various small minnows
that like shallow and rapidly-moving water, and brook lamprey.
A typical Great Basin stream, on the other hand, being muddier,
deeper, and warmer, may contain catfish, suckers, many minnows,
and members of the Family Centrarchidae, with bass and sunfish
of various kinds.
The streams in Duluth and along the North & South Shores are,
in general, very similar, so we find similar fish communities
throughout the region. The list to the right shows the most
common fish found in Duluth streams. These are the fish most
often caught during MN DNR Fisheries surveys or during various
research projects. We will soon be posting the actual survey
results.
