Tackle & technique

Leopard shark
Leopard sharks cruise shallow mudflats, sloughs and channel edges in bays, most often in less than 15 feet of water, and follow the flooding tide onto the flats to feed on crabs, worms, clams and small fish. Anchor or fish from shore or a pier with a sliding sinker rig and a chunk of squid, mackerel or ghost shrimp on the bottom. The bite is often better into the evening and at night.
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.
