Tackle & technique
- 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.
- Striped bass
- Striped bass feed where moving tide pushes bait past structure: inlets, points, jetties, bridge pilings and rips in the surf, usually in 2 to 40 feet of water. Fish dawn, dusk and night hardest, casting plugs, bucktails and soft plastics or drifting live bunker and eels, and chunk bait on the bottom in current. In midsummer the larger fish drop deeper or feed mostly after dark.
- 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.
