Coho is the silver of Pacific salmon — bright chrome bodies, aggressive strikes, and the most accessible of the major Pacific salmon species. Adult Coho run 6-15 pounds typically (with trophy fish reaching 20+ pounds), smaller than Chinook but compensating with attitude. Where Chinook nose bait deliberately, Coho commit aggressively to lures and bait. Where Chinook hold deep, Coho work the upper water column where surface trolling and casting both produce. Where Chinook reward patience, Coho reward active fishing. For PNW anglers who like to actively cast, retrieve, and feel hits — Coho are the species.
This guide covers Pacific Coho fishing — the run timing, techniques specific to the species, gear specifications lighter than Chinook setups, and top destinations from the Olympic Peninsula to Tillamook. Coho fishing extends later into fall than Chinook (October-November productive), giving anglers an extended season after the Chinook runs wind down. Pair with the Pacific salmon fishing guide for broader silo context and the technique-specific guides as appropriate.
Identifying Coho Salmon
- Size: 6-15 lbs typical adult, 20+ lbs trophy potential. Smaller than Chinook, larger than Pink or Sockeye.
- Coloration: Bright chrome silver in ocean, transitioning to dark red as they enter rivers. The freshwater coloration is what gives “silvers” their summer-name and “hooknose” their late-season name (male jaw extends into a hooked kype).
- Mouth: White or light gum line (vs Chinook’s black gums) — the most reliable identifier.
- Tail spots: Only the upper tail lobe is spotted; lower lobe is unspotted (Chinook have spots on both lobes).
- Body shape: Slimmer and more athletic than Chinook; more substantial than Pink or Sockeye.
Common alternative names: “silver salmon” is the most-used vernacular; “hooknose” references the late-season male morphology. The species is Oncorhynchus kisutch.
Coho Run Timing
Coho enter PNW rivers and ocean fisheries on a compressed timeline compared to Chinook — most of the action happens from August through November:
| Period | Activity | Location |
|---|---|---|
| July (early) | Early ocean Coho | Westport, ocean ports |
| August-September | Ocean Coho peak | All Pacific ports |
| September | River entry begins | Lower Columbia, smaller PNW rivers |
| October | River Coho peak | Most PNW rivers |
| November | Late Coho, upstream spawning | Smaller streams, upper river sections |
| December | End of run | Spawning fish only |
Coho fishing extends past Chinook by 4-6 weeks — September-November is dominant for Coho when Chinook fisheries are winding down. This makes Coho the natural follow-on species after the August-September Chinook peak.
Where to Fish Pacific Coho
Ocean Ports
Westport, Ilwaco, Sekiu, Neah Bay, Newport, Garibaldi all produce Coho during the ocean peak. Surface trolling with downriggers set shallow (15-40 feet) is dominant. Charter operations target Coho exclusively from late July through early September.
Columbia River and Tributaries
Coho enter the Columbia in September; the Cowlitz, Lewis, Kalama, Sandy, and Clackamas all support strong Coho returns. Bobber-doggin’ with cured eggs is the dominant river technique, with spinner casting as a strong alternative.
Puget Sound
Coho appear in Puget Sound from August through October. Various locations support Coho fishing — open water trolling, pier fishing, shore casting at specific marine access points. The Puyallup, Skagit, Snohomish, and Skykomish rivers see Coho returns into their tributaries.
Olympic Peninsula Rivers
Coho on the Hoh, Queets, Quillayute, Sol Duc, and Bogachiel run October-November. Wild Coho in remote rainforest settings. Fly fishing for these fish has a serious following; conventional spinner casting and bobber-doggin’ both produce.
Oregon Coast Rivers
Tillamook Bay area rivers (Wilson, Trask, Kilchis, Miami, Tillamook), Nehalem, Siletz, Alsea, and Umpqua all support Coho fisheries. Smaller scale than Columbia or Puget Sound but high-quality fishing in beautiful settings.
Coho Techniques
The species-specific techniques that produce Coho consistently:
Surface Trolling (Ocean)
Coho hold higher in the water column than Chinook — typically 15-40 feet down. Downriggers set shallow, planer board systems, or flatlines with weight all reach Coho depths. Spoons, plugs, and bait wraps all produce; Coho strike aggressively on most presentations.
River Spinner Casting
The iconic river Coho technique. Cast a Blue Fox Vibrax #6 or Mepps Aglia #4-5 across the river to far structure, retrieve at moderate-fast cadence. Coho commit aggressively. Chrome and chrome/blue patterns dominate.
River Bobber-Doggin’
Coho readily take cured eggs paired with Spin-N-Glo drift bobbers. The technique works on most PNW Coho rivers and produces in conditions where casting is impractical (high water, deep pools, brush-lined banks). See the bobber-doggin’ guide.
Estuary Casting
Coho stage in lower tidewater zones before pushing upriver. Casting spinners or small spoons in estuary settings (Tillamook Bay flats, Columbia tidewater) produces during the August-September staging period.
Light Mooching
Mooching for Coho uses smaller bait (cut herring fillets vs whole herring), lighter weight, and more aggressive presentation (faster jigging motion vs Chinook’s drift). The technique works but is less established for Coho than for Chinook. See the mooching guide.
Coho Gear Setup
Coho gear scales down from Chinook setups:
- River casting: 8’6″-10′ medium-heavy rod, Shimano Curado 200 baitcaster or large spinning reel, 15-20 lb braid mainline with 12-15 lb fluorocarbon leader
- Bobber-doggin’: 10’6″ St. Croix Onchor or similar, Curado 200, 15-20 lb braid, 12 lb fluorocarbon leader, Beau Mac float, Spin-N-Glo with cured eggs
- Ocean trolling: Standard trolling rod with Shimano Tekota 600, 20-25 lb mainline, shallower downrigger settings (15-40 ft)
- Spinner casting: 8’6″-9′ medium-heavy rod, Curado, 15-20 lb braid, 12 lb fluoro leader, Vibrax #6 or Mepps #4-5
Coho fight hard for their size — light gear is satisfying but ensure the rod has enough backbone to set the hook on the aggressive strike. See the best Pacific salmon rods guide.
Reading Coho Behavior
Aggressive strikes. Coho hit lures hard. The first sign of a Coho is often a hard tap or a sudden weight change as the fish chases and grabs the lure. Set hook immediately.
Acrobatic fights. Hooked Coho often jump multiple times during the fight. The line goes slack briefly when the fish is airborne — keep the rod tip up and reel in slack as the fish re-enters water.
Schooling behavior. Coho often travel in groups. When you catch one, more are usually nearby. Stay in the productive zone after a hookup.
Reaction to color. Coho respond strongly to chrome, silver, and bright fluorescent colors. Chartreuse, hot pink, and orange patterns produce in stained water. Natural patterns work in clear water.
Selectivity in clear water. Despite their aggression, Coho in very clear conditions can be selective. Light leader (10-12 lb fluorocarbon) and smaller presentations sometimes outproduce heavy gear.
Tidal influences. Tide stage matters significantly in estuary Coho fishing. Generally outgoing tides concentrate fish at river mouths; incoming tides push them upstream.
Best Months by Destination
| Destination | Peak Months | Primary Technique |
|---|---|---|
| Westport, WA | August-September | Surface trolling |
| Sekiu / Neah Bay | August-September | Trolling, mooching |
| Lower Columbia River | September-October | Bobber-doggin’ |
| Cowlitz River | September-October | Bobber-doggin’, spinner casting |
| Puget Sound | August-October | Trolling, pier casting |
| Tillamook Bay | September-October | Estuary and river casting |
| Olympic Peninsula rivers | October-November | Spinner casting, fly fishing |
| Oregon Coast rivers | September-November | Spinner casting, bobber-doggin’ |
Common Mistakes
Heavy gear for the species. 25-30 lb mainline isn’t necessary for 8-12 lb Coho. Scale gear down for better presentation and more sporting fights.
Slow retrieve speed. Coho respond to moderate-fast retrieves. Slow trolling that produces Chinook misses Coho. Speed up for active Coho.
Wrong depth. Coho hold shallower than Chinook. Setting downriggers at Chinook depths (60-80+ feet) catches fewer Coho than 15-40 foot settings.
Single technique per session. Coho respond to different presentations on different days. Carry casting gear AND bobber-doggin’ gear; switch between techniques during productive water.
Ignoring stained water adjustments. Post-rain rivers run stained. Switch from chrome to fluorescent colors (chartreuse, fire tiger) when water clarity drops.
Mishandling jumps. When Coho jump, rod should follow the fish — drop the tip slightly to maintain a bend, or the fish may shake free on the next jump. Don’t keep the rod high through a jump.
Late-season aggressive setting. Late-season “hooknose” Coho become selective. Subtle presentations sometimes outproduce aggressive ones for educated fall fish.
Frequently Asked Questions
What’s the difference between Coho and Chinook?
Coho are smaller (6-15 lbs vs 15-40+ lbs), have white gum lines (vs Chinook’s black gums), have spots only on the upper tail lobe (Chinook have both), and are more aggressive on lures. Different fishing techniques work better for each.
When is Coho season?
August-November is the primary Coho window. Ocean peak August-September; river peak September-October; late river run October-November. Coho fishing extends past Chinook by several weeks.
What’s the best lure for Coho?
Blue Fox Vibrax #6 is the river Coho killer. Mepps Aglia #4-5 is the strong alternative. Chrome and chrome/blue patterns produce; chartreuse and orange in stained water.
Can I catch Coho from shore?
Yes — pier fishing in Puget Sound, bank fishing on rivers, estuary casting at PNW river mouths. Coho are more shore-accessible than Chinook because they hold shallower and enter estuaries actively.
What’s the best rod for Coho?
A 10’6″ medium-heavy salmon rod handles most Coho applications. The St. Croix Onchor is the workhorse choice. Lighter rods (8’6″-9’6″ medium power) work for spinner casting and pier fishing.
Why are Coho called silvers?
In their ocean phase, Coho have bright chrome silver bodies. The vernacular “silver salmon” reflects this appearance. As they enter rivers and approach spawning, they transition to dark red bodies — that’s when they’re called “hooknose” or just “Coho.”
Can I keep wild Coho?
Depends on river and current regulations. Many PNW rivers have selective retention requiring release of wild fish (identified by intact adipose fin); hatchery fish (clipped fin) can be kept. Verify current regulations before each trip.
