Tackle & technique
- Chum salmon
- Chum stage off stream mouths and hatchery beaches in late fall in Puget Sound and Hood Canal and in midsummer in Southeast Alaska. Fish from the beach or a skiff in 5 to 30 feet with a green or cerise jig under a float, a large fly or a spoon. They fight hard, so step up to 12 to 20 pound line.
- Chinook salmon
- Chinook hold near bait off points, kelp edges and tide rips, usually suspended 20 to 120 feet down and deeper as the sun gets higher. Troll slowly, under 2 mph, with a flasher and herring, hoochie or spoon on a downrigger, or mooch a plug-cut herring at the depth where the sounder shows bait. Winter blackmouth and feeder kings sit within 10 feet of the bottom in 60 to 200 feet.
- Coho salmon
- Coho feed in the top 30 to 50 feet along tide rips, kelp edges and bait schools, and often hit within a few feet of the surface. Troll faster than for Chinook, 2 to 4 mph, with a small flasher and hoochie, bucktail fly or herring, or cast spinners and flies from beaches near stream mouths as fish stage in late summer. The hour around a tide change is often the best window.
