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.
- Striped bass
- Striped bass feed where moving tide pushes bait past structure: inlets, points, jetties, bridge pilings and rips in the surf, usually in 2 to 40 feet of water. Fish dawn, dusk and night hardest, casting plugs, bucktails and soft plastics or drifting live bunker and eels, and chunk bait on the bottom in current. In midsummer the larger fish drop deeper or feed mostly after dark.
- Lingcod
- Lingcod ambush prey from rock outcrops, reef edges and kelp where current runs, most often in 30 to 300 feet, and males move shallow to guard nests in winter. Drift over the reef bouncing a lead-head swimbait or metal jig on the bottom, or fish herring or squid on a heavy leader, since their teeth cut light line. From jetties and rocky shore, work bait or jigs along the rocks on the incoming tide.
