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.
- 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.
- Kelp greenling
- Kelp greenling are solitary bottom fish of rocky shores, jetties and kelp beds, usually in water shallower than 60 feet. Use a small number 4 to 6 hook with sand shrimp or marine worms, or a small lead-head grub, dropped to the bottom and reeled up slightly. Larger fish show in October and November when they spawn close to shore, and mornings tend to fish best.
