Tackle & technique
- Surfperch
- Surfperch feed in the troughs and holes within about 30 feet of the waterline, just outside the first set of breakers. Cast a two-hook high-low or Carolina rig with size 4 to 2 hooks and a 1 to 6 ounce pyramid sinker and let the surge work it through the trough. Fish the incoming tide on beaches with a steep drop, and switch to jetties, pilings and bays when the surf is too big.
- 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.
