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.
- 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.
- White seabass
- White seabass hold along kelp bed edges and over nearby sand where market squid gather, usually in 20 to 80 feet of water and shallower as the water warms. Fish a live squid on a dropper loop or fly-line a sardine near the kelp at dawn, dusk and after dark, especially around the spring full moon. Tagged fish spend most of their time in 52 to 66 degree water.
