About Coho Salmon

Coho Salmon — also called Silver Salmon — are prized for their aggressive surface strikes and spectacular aerial acrobatics. Averaging 8-12 pounds, they are smaller than kings but pound-for-pound are considered harder fighters. Ocean-phase coho are brilliant chrome-silver with small black spots confined to the upper lobe of the tail and the back above the lateral line. Spawning males turn deep red on the sides with a dark green head and develop a dramatic hooked jaw. Females become darker but retain more of their shape.

Identification & Appearance

Bright chrome-silver ocean fish with small black spots on the upper back and upper lobe of the tail only (key identifier — kings have spots on both tail lobes). White gum line on lower jaw (kings have black gums). Dark metallic blue-green back. Spawning males turn deep crimson-red on sides with dark green head, prominent kype, and humped back.

Male vs. Female

Males develop an extreme hooked jaw, humped back, and deep red flanks during spawning — one of the most dramatic transformations in the salmon family. Females become darker but retain a more normal body shape. Both die after spawning.

Size, Weight & Records

Average ocean catch is 8-12 lbs. Quality coho run 12-18 lbs. Trophy fish exceed 20 lbs. The all-tackle world record is 33 lbs 4 oz. Washington and Oregon produce the largest ocean-caught coho. River fish average slightly smaller due to energy expenditure during migration.

Popular Bait & Fishing Methods

Best Techniques

Ocean trolling with herring, hoochies (plastic squid lures), or spoons behind flashers at 15-60 feet is the primary technique. Coho often feed higher in the water column than kings, so shallower presentations work well. Casting buzz bombs, Crippled Herring spoons, and spinners into surface-feeding schools produces explosive strikes. In rivers, casting spinners (Blue Fox, Panther Martin), drifting roe under a float, or swinging flies on a sink-tip line are all effective. Coho are aggressive and respond well to fast-moving presentations.

Recommended Tackle

Ocean: 7-8'6" medium rod, level-wind or spinning reel, 15-20 lb mono or 30 lb braid. River: 8'6"-9'6" medium rod, spinning reel, 10-15 lb line, 8-12 lb fluorocarbon leader. Fly: 7-8 weight rod, sink-tip line, bright patterns (Clouser, Bunny Leech, Egg-Sucking Leech).

Regulations & Bag Limits

Coho regulations vary significantly by state and water body. Most areas have a 2-fish daily limit. Hatchery (fin-clipped) vs. wild retention rules apply — many rivers are catch-and-release only for wild coho. Barbless hooks required in many areas. Oregon and Washington have complex zone-specific regulations. Check current rules carefully.

Regulations change frequently. Always verify current rules with your charter captain or state wildlife agency before fishing.
