Coho Salmon
Silver Salmon
Known for their aggressive strikes and acrobatic fights, Coho are a favorite among sport anglers, especially from July through September. These spectacular fighters are famous for their aerial displays when hooked.
Migratory Patterns
Juvenile Coho spend one to two years rearing in freshwater streams and rivers before migrating to the ocean.
They typically spend 18 months at sea. While some migrate offshore, many remain in coastal waters along the continental shelf.
They generally return to spawn as three-year-old adults.
How They Live
In the ocean, they feed aggressively, often near the surface, on plankton, crustaceans, and small baitfish, growing rapidly.
Coho are highly adaptable and can utilize very small tributaries and streams for spawning and rearing.
Interesting Details
During spawning, males develop a distinctive hooked snout, known as a kype, and turn a deep red color.
Some males mature early and return to spawn as two-year-olds, known as “jacks.”
Regulations (Area 12)
Retention Rules: Regulations strictly manage the retention of wild (unmarked) vs. hatchery-marked (adipose fin clipped) Coho, and rules vary by subarea.
Example:
- • In many parts of Area 12, retention may be limited to only hatchery-marked fish
- • In other subareas (like 12-14), one wild Coho may be permitted
Best Season
July through September
Peak activity typically in August
