Tackle & technique

Pacific halibut
Halibut sit on sand and gravel bottoms near drop-offs, bars and pinnacles, most often in 90 to 500 feet in Alaska and on the shelf off Washington, Oregon and far northern California. Anchor up-current of a likely edge and fish herring, squid, octopus or a salmon head on a circle hook with 24 to 32 ounces of weight, or bounce a large jig on the bottom. The best bite usually comes in the hour around slack tide.
Pacific cod
Pacific cod school over mud, sand and gravel bottoms and shelf edges, moving shallower than 300 feet in summer and deeper to spawn in winter. Drop a heavy metal jig or a lead-head with a herring or squid strip to the bottom in 100 to 300 feet and work it a few feet up. They often come up on the same drifts as halibut, and a school can mean fast fishing once you find it.
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.
