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.
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.
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.
