Tackle & technique
- 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.
- 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.
