Step-by-step: how to catch it
- Go where it lives: Ocean off Oregon and Washington, the Strait and Puget Sound; rivers from Northern California north.
- Rig up: 8½–10½ ft salmon (mooching) rod with a level-wind or mooching reel; downriggers or divers to get deep. 20–30 lb fluorocarbon, 4–6 ft behind a flasher.
- Pick your bait: Herring and anchovies. Lures: Hoochies, spoons and bucktail flies trolled fast near the surface; spinners in the rivers.
- Fish it: Troll faster and shallower than for chinook, often with no weight at all; watch for birds and bait.

- BigJoe's tip
Coho love speed and flash — when they're in, troll fast in the top 30 ft.
- 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
Excellent eating — one of the best-tasting fish in its range.
- Cleaning
Bleed and ice it right away. Fillet, then remove the skin and any dark bloodline.
- Cooking suggestions
Mild, orange meat, a bit leaner than chinook: grill, bake or smoke.
Stay safe & legal
Safety, rules and taking care of the fishery.
- Safety warnings
River bars can be deadly — check the bar report and Coast Guard restrictions before crossing.
- Regulations
Many areas allow only hatchery coho (with a clipped adipose fin) to be kept. Seasons are set each year. Check ODFW or WDFW. Licenses, size and bag limits and seasons are set by each state — the California Department of Fish and Wildlife (wildlife.ca.gov), Oregon Department of Fish and Wildlife (myodfw.com) and Washington Department of Fish and Wildlife (wdfw.wa.gov) — together with NOAA Fisheries and the Pacific Fishery Management Council. Rules change often, and many areas are no-take marine reserves: check before you go.
- Conservation
Keep only what you'll eat, release the rest quickly, and follow size and bag limits.
