Conservation
The bull trout is listed as a threatened species under the U.S. Endangered Species Act throughout its range in the contiguous United States. It is used as a management indicator species for several national forests, including Boise National Forest and Sawtooth National Forest (Sawtooth National Recreation Area). Bull trout reproduction requires cold water and very low amounts of silt, both of which are negatively impacted by road building and logging. Additionally, the bull trout's need to migrate throughout river systems may be hindered by impassible fish barriers, such as dams.
Bull trout populations are also in danger from hybridization with non-native brook trout.
They are a prized game fish in northern Canada. Indeed, the fish was once maligned out of fear they threatened populations of other native species more prized by anglers. Some jurisdictions publicize the requirement to release with the slogan "No black, put it back."
