Yukon population estimate

Not determined.


While Lake Whitefish can be found throughout the Yukon’s lakes and rivers, they prefer cool water and tend to move deeper as surface waters warm in summer. They spawn in autumn and early winter in the shallow water of lakes and rivers, on gravel or sandy bottoms. They spawn at night so little is known about their spawning behaviour. Northern populations grow much slower but live longer than southern populations.


Aquatic insects, molluscs, crustaceans and small fish.
