Areas of a lake with a course gravel or boulder bottom are chosen as spawning sites. Males usually enter the spawning area first. After a few days the female enters the area, and several males may spawn in groups with one or more females. No apparent changes in physical appearance occur in lake trout during the spawning season. The young lake trout eat insects and crustaceans.
Larger individuals feed heavily on fish.
