Starting Friday, fishermen casting their lines at the Buoy 10 salmon fishery at the mouth of the Columbia River will only be allowed to keep hatchery Chinook.
Buoy 10 is the name given to the 16 miles from where the Columbia meets the Pacific Ocean upstream to Tongue Point in Oregon and Rocky Point in Washington.
The Columbian reports that the Chinook fishing has been excellent there so far this season.
So far in August, anglers caught more than 13,000 Chinook, prompting the switch to allowing them to keep hatchery-only fish.
Managing fall chinook harvest is a complicated balancing act with allocations set among tribal members, sport and commercial fishermen.
While only hatchery chinook will be legal at Buoy 10, keeping wild chinook will still be allowed in the ocean off the Columbia River mouth and upstream of Tongue Point.
