Tackle & technique
- 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.
- 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.
- Kelp greenling
- Kelp greenling are solitary bottom fish of rocky shores, jetties and kelp beds, usually in water shallower than 60 feet. Use a small number 4 to 6 hook with sand shrimp or marine worms, or a small lead-head grub, dropped to the bottom and reeled up slightly. Larger fish show in October and November when they spawn close to shore, and mornings tend to fish best.
