Natural History

Lake Trout are native to Lake Superior and were one of the most heavily impacted by Sea Lamprey in the mid-part of this century. Thanks to lower lamprey numbers and stocking efforts, the Lake Trout populations are on the rise again. This fish reaches maturity later in life at age 6-8 and typically lives for 8-10 years. You can recognize this fish by its torpedo shaped body, dorsal and adipose fin and light spots on a dark background coloration. A popular game fish, Lake Trout is often served in local restaurants.
