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.
- California halibut
- California halibut are ambush feeders that lie on sand or mud bottom, mostly in water shallower than 100 feet and often inside bays, harbors and estuaries. Drift or slow-troll a live anchovy or sardine on a sliding sinker rig, or bounce a swimbait along the bottom over flats, channel edges and sandy areas near structure. Keep the bait within a foot or two of the bottom and give a fish time to turn the bait before setting the hook.
- 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.
