Bull Trout Fishing Guide

The bull trout (Salvelinus confluentus) is a large western char that requires the coldest, cleanest water of any salmonid in North America — they are a strict indicator of pristine, undisturbed watersheds. Adults are pale-spotted (no red spots, no black spots, only pale yellow and orange spots on a dark olive-green body), and they grow large enough to eat other trout. Bull trout are listed as threatened under the Endangered Species Act in the contiguous US, and possession is generally illegal across most of their range — Idaho, Montana, Washington, and Oregon. Populations exist in two forms: residents that spend their entire lives in streams, and migratory fish that move into large rivers or lakes. The closely related Dolly Varden (Salvelinus malma) of Alaska and the Pacific Northwest is a separate species that looks nearly identical.

Bull Trout is a freshwater species.

Habitat

Cold headwater streams and river systems of the northern Rocky Mountains, Cascade Range, and Klamath Mountains; some populations move into large rivers or deep, cold lakes. Require water temperatures consistently below 55°F and are among the most habitat-sensitive fish in North America.

Diet

Highly piscivorous predator consuming other salmonids (cutthroat, rainbow trout), mountain whitefish, sculpins, and suckers. Adult bull trout are apex predators in their stream systems and are the dominant large predator in pristine Rocky Mountain rivers.
