Catch it

Step by step, from first cast to landing.

Step-by-step: how to catch it

  1. Go where it lives: Cold rivers and lakes of the Rocky Mountains and Great Basin (Yellowstone, Snake River, Pyramid Lake) and coastal streams and estuaries from northern California to Alaska.
  2. Rig up: 9 ft 4–6 weight fly rod or light spinning rod. 4X–5X tippet.
  3. Pick your bait: Worms and salmon eggs where bait is allowed. Lures: Small spinners and spoons.
  4. Fish it: Drift dry flies, hoppers or nymphs through riffles and current seams; cutthroat often take on a slow, deliberate rise.
  5. Time it: Morning, evening and during hatches. No tide — in rivers, falling water after the rainy season is best.
Fishing techniques

Drift dry flies, hoppers or nymphs through riffles and current seams; cutthroat often take on a slow, deliberate rise.

BigJoe's tip

Wait a beat before setting the hook — cutthroat rise slowly.

Catch and release

Catch and release: wet your hands, keep the fish in the water when you can, and release it quickly. Use circle hooks and a dehooker.

Clean & cook

Is it good to eat, and how to prepare it.

Edibility

Good eating when fresh.

Cleaning

Bleed and ice it right away. Fillet, then remove the skin and any dark bloodline.

Cooking suggestions

Pink, mild meat where harvest is allowed; most anglers release wild cutthroat.

6

Stay safe & legal

Safety, rules and taking care of the fishery.

Safety warnings

Bears in much of its range — carry bear spray. Cold, fast rivers.

Regulations

Many waters are catch-and-release or single-hook for cutthroat, and some subspecies are federally threatened; check local rules. In Alaska, rules are set by the Alaska Department of Fish and Game (adfg.alaska.gov); in Canada, by each province and territory. Many trout and char waters are single-hook, artificial-lure or catch-and-release only — check before you go.

Conservation

Mixing with rainbow trout and competition from introduced trout threaten many populations.
