Tackle & technique

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.
Lingcod
Lingcod ambush prey from rock outcrops, reef edges and kelp where current runs, most often in 30 to 300 feet, and males move shallow to guard nests in winter. Drift over the reef bouncing a lead-head swimbait or metal jig on the bottom, or fish herring or squid on a heavy leader, since their teeth cut light line. From jetties and rocky shore, work bait or jigs along the rocks on the incoming tide.
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.
