SEATTLE (AP) — Federal officials are proposing to curtail nontribal salmon fishing along the West Coast in especially bad years to help the Northwest’s endangered killer whales. NOAA Fisheries is taking public comment on the plan, which calls for restricting commercial and recreational salmon fishing when Chinook salmon forecasts are especially low. The restrictions would extend from Puget Sound in Washington to Monterey Bay in central California, and they would be triggered when fewer than 966,000 Chinook are forecast to return to Northwest rivers. The last time forecast Chinook returns were that low was in 2007.
