Tackle & technique
- 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.
- 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.
- 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.
