Yukon population estimate
Bull Trout have a voracious appetite making them susceptible to over-harvest. Furthermore, they habitually congregate during spawning time, bringing a population to concentrated locations. Bull Trout is an exclusively freshwater fish that spawns in the autumn on gravel bottoms of stream and river outlets and inlets.

Bull Trout and people
- Bull Trout were known as Dolly Varden until the 1980s when they were reclassified as their own species.
- Bull Trout and Dolly Varden are extremely difficult to tell apart, making geography the easiest way to distinguish the two. If found in the Liard drainage the fish is likely a Bull Trout, while those found elsewhere in Yukon are likely Dolly Varden.
