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!

Note to observers

This page explains general clues to watch and listen for when observing lake whitefish phenology. However, this page does not explain how to identify this fish or collect data in a standardized way.

View of a lake whitefish through thin, clear ice. The fish is silvery-gray with dark, triangular shaped fins.
A tiny sliver of a fish larva is resting on the observer's thumb. The larva is so small that it only takes up about one third the length of the thumbprint area.
A small juvenile lake whitefish is in a small plastic container so its length can be measured. The background shows a large lake and a distant, wooded horizon.
Two river otters are in blue, rippled water. One has a fish in its mouth.
