The Coho, or “Silver Salmon”, has a metallic blue back and silver sides and belly. The adults turn muddy red as they begin their spawning run. Black spots are scattered along the back and upper tail. Their mouths are black except for a thin white line along their gums. The average size is 8 lbs., but fishers have caught Coho heavier than 30 lbs.
Coho adults return to the Columbia in the fall of their third year. The female may dig several redds and will deposit a total of 3,000 – 4,000 eggs.
The Coho run up the Columbia River starts in August and continues through November. These beautiful fish are bright chrome and a lot of fun. They average 11-14 pounds but an occasional 18-20 pounder will try to take your rod away from you.
