Tackle & technique

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.
Rockfish
Rockfish live on rocky reefs, pinnacles and kelp from the shoreline out past 300 feet, with black and blue rockfish schooling mid-water over shallow reefs and copper, quillback, yelloweye and vermilion sitting tight to deeper bottom. Drift over the structure with a shrimp fly above a lead-head grub or metal jig, or a squid strip, and reel up a few cranks after touching bottom to cut snags. Use a descending device to release any fish brought up from deep water.
White seabass
White seabass hold along kelp bed edges and over nearby sand where market squid gather, usually in 20 to 80 feet of water and shallower as the water warms. Fish a live squid on a dropper loop or fly-line a sardine near the kelp at dawn, dusk and after dark, especially around the spring full moon. Tagged fish spend most of their time in 52 to 66 degree water.
