Some whitefishes actually even have teeth on their tongues. Whitefish typically don't have many spots, but some varieties do have faintly spotted tails. Whitefish will always be found in schools. They aren't the type to wander around alone. Whitefish are carnivorous, always looking in groups for a good meal of smaller fish.
Whitefish vary quite a bit when it comes to spawning.
The season they spawn often changes from year to year, and it is quite dependant on where they are breeding. Many accounts show that whitefish spawn in every month of the year except the hottest, July. Whitefish are known as traditional food fish. Commercial fisheries thrive, especially in the Great Lakes region, on catching large quantities of this tasty seafood. Because of the demand for whitefish commercially, pollution, and attacks on whitefish by predators have caused there to be a significant reduction in the number of whitefish living naturally.
