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.
- 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.
- Cabezon
- Cabezon sit in rock crevices, kelp beds and jetty boulders from the intertidal zone to about 100 feet and feed mostly on crabs and small fish. Fish a fish-finder rig with sand shrimp, squid or crab right on the bottom in the rocks, or drag a lead-head grub slowly through the kelp. Expect snags, and do not eat the roe, which is toxic.
