(Salvelins confluentus) |
Bull trout can be identified as greenish to brown on their back and sides, few or no spots on their fins, with cream or yellowish spots on their sides. Some spots along the side may be deep orange to red. The leading edges of their ventral fins are white. Bull trout are considered a char and are closely related to dolly varden, eastern brook trout, and lake trout.Bull trout are fierce predators on other fish and can reach sizes of 20 pounds in some Oregon rivers. These trout rely on cold clean water for their survival. Bull trout have a variety of life history strategies that include highly migratory and non-migratory populations. Spawning occurs in the Fall when water temperatures drop below 50 degrees F. Usually, juvenile bull trout feed on insects until they are large enough to transition their diet to fish. Adult bull trout primarily feed on fish.
