Tackle & technique

Surfperch
Surfperch feed in the troughs and holes within about 30 feet of the waterline, just outside the first set of breakers. Cast a two-hook high-low or Carolina rig with size 4 to 2 hooks and a 1 to 6 ounce pyramid sinker and let the surge work it through the trough. Fish the incoming tide on beaches with a steep drop, and switch to jetties, pilings and bays when the surf is too big.
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.
