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.
California yellowtail
Yellowtail school around the offshore islands, banks, high spots and kelp paddies from spring into fall, moving north from Baja as the water warms past about 64 degrees. Fly-line a sardine or mackerel, cast a surface iron to breaking fish, or drop a heavy iron and wind it fast when they hold deep. Heavy line matters because they run straight for kelp and rock.
Kelp bass
Kelp bass live in kelp beds, rocky reefs and breakwaters, most often in 9 to 70 feet of water, and seldom move far from home. In summer cast swimbaits or fish live anchovies along the up-current edge of the kelp and let them swim into the canopy. In winter the bigger fish move to reefs in 90 feet or more, where a squid-tipped jig works better.
