About the lake whitefish
- The lake whitefish is a member of the trout family that can be identified by its deeply forked tail and the presence of an adipose fin. They are silvery-white in color and grow to about seventeen to twenty-two inches long.
- As bottom dwellers, lake whitefish eat zooplankton, snails, larvae, and small fish.
- The spawning season for lake whitefish is late fall to early winter in Minnesota, depending on water temperatures. A single female can lay 10,000 to 130,000 eggs, which then sink to the lake bottom. The eggs develop through winter and hatch in spring as small fry.
- Lake whitefish is part of the traditional diet of many Native American tribes of the Great Lakes. It is eaten cooked, smoked, powdered, or in stews.
- Fun fact: The largest lake whitefish on record was caught in Lake Superior in 1918. It weighed a whopping 42.67 pounds!
