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.
- Rockfish
- Rockfish live on rocky reefs, pinnacles and kelp from the shoreline out past 300 feet, with black and blue rockfish schooling mid-water over shallow reefs and copper, quillback, yelloweye and vermilion sitting tight to deeper bottom. Drift over the structure with a shrimp fly above a lead-head grub or metal jig, or a squid strip, and reel up a few cranks after touching bottom to cut snags. Use a descending device to release any fish brought up from deep water.
- 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.
