Tackle & technique
- 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.
- 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.
- 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.
