Best baits & lures

Recommended gear for this species
Rod · Best value
7'6" medium-heavy jigging rod
≈ US$110-170
Works 2-6 oz jigs over rock and reef and still has the backbone to lift a halibut off the bottom.
Line · Budget
50 lb braid with 40 lb leader (200 yd)
≈ US$25-40
Thin braid cuts the current so jigs stay vertical; the leader shrugs off rock and teeth.
Terminal · Budget
Leadhead jigs, swimbaits and two-hook bottom rigs
≈ US$25-40
A leadhead with a swimbait tail is the universal bottom-fish catcher, from rockfish to cod to flounder.
