Where they live
How to catch them
Bottom fishing with natural bait Boat
Rig: Two-hook paternoster or Carolina rig with 1-3 oz sinker
Bait/lure: Live or fresh shrimp
Key tip: Keep the bait on the bottom over sand or mud and wait for the soft, tapping bite.
Live-bait fishing under structure Boat
Rig: Circle hook on fluorocarbon leader, free-lined or under a float
Bait/lure: Live shrimp or small live baitfish
Key tip: Present the bait beside floating debris, pilings or buoys and be ready for a slow, powerful run.
Slow jigging and soft plastics Boat
Rig: Light jigging rod with 1/2-2 oz jig head or metal jig
Bait/lure: Shrimp-imitating soft plastic or small metal jig
Key tip: Work the lure slowly just above the bottom; most strikes come on the fall.
Best baits & lures
Baseline setup
- Rod: Medium spinning or conventional rod 7-9 ft
- Line: 20-30 lb braid with 30 lb fluorocarbon leader
- Terminal: 2/0-4/0 circle hooks, 2-4 oz sinker or jig
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.
