Bull Trout

Habitat

Require the coldest, cleanest water in Alberta. Found in mountain streams, rivers, and cold lakes of the eastern slopes. Extremely sensitive to habitat degradation. Need connected waterways for migration.

Seasonal Patterns

Spring: Rivers opening from ice; feeding aggressively. Summer: Deep, cold pools in rivers; lake fish go deep. Fall: Migration to spawning tributaries (September-October). Winter: Slow metabolism; found in deepest pools.

Fishing Techniques

• Fly fishing: Large streamers stripped through pools
• Casting: Large spinners and spoons in rivers
• Still fishing: (where allowed) with large bait near structure

Best Lures

• Large articulated streamers (Dolly Llama, Meat Whistle)
• Big spinners (#4-5) in silver or copper
• Jointed Rapalas
• Soft plastic swimbaits

Best Bait

• Note: Check regulations—bait is prohibited in many bull trout waters

Alberta Regulations

Pro Tips

• This is a protected species—handle with care and release immediately
• Use single barbless hooks for easy release
• Keep the fish in water while removing hooks
• If you must lift, support the belly—never hold by the jaw
• Photograph quickly and release in calm water
