Sexual maturity is reached by about 3-4 years of age.


Identifiable as a member of the Trout/Salmon family (Salmonidae) by its body shape and adipose fin.
While some 14 similar and confusing species of Coregonus are found in Canada and the northern US, only 2 are native to the Boundary Waters.
Cisco is distinguished from Lake Whitefish (Coregonus clupeaformis) by lower jaw extending up to or beyond the tip of snout numerous, fine gillrakers


A pelagic species often found in the cooler water below the thermocline in lakes where thermal stratification develops. Also thrive in shallow, eutrophic lakes.
Relatively shallow waters of the Great Lakes; infertile inland lakes more than 30' deep.
Tend to swim in large schools at midwater depth, moving to shallower water in fall as upper waters cool.


Mainly plankton; also terrestrial and aquatic insects, minnows, and fish eggs.
An important food for large game fish.


Minnesota Record: 4lbs 3oz, from Big Sandy Lake (Aitkin County).


Though sometimes taken on rod and reel, its main importance to anglers seems to lie in its role as food for larger game fish, especially Lake Trout (Salvelinus namaycush).
Harvested by commercial fishermen and of some economic importance as a food fish. Marketed whole, dressed, and smoked. The flesh of these fish is palatable. It is also caught through the ice on jigs.

Reproduction:Spawning occurs in late fall when water temperatures drop below about 40º F, when large spawning groups congregate. Males move to spawning areas before females. In inland lakes, spawning usually takes place in shallow water (3-10 feet deep) over almost any type of bottom, but often over gravel or stony substrate. In large lakes, spawning may occur in shallow water or in deep water. About 20,000-29,000 eggs are deposited on the lake bottom by each female; no parental care is given eggs or young, which hatch early the following spring.


The common name Tullibee is credited to early Canadian fur traders and is most commonly used in north Ontario, the Prairie Provinces, and the Northwest Territories.
