Techniques for Bandtail Puffer →

Baseline setup

Rod: Light spinning rod 6-7 ft
Line: 8-12 lb braid or mono
Terminal: Small hook No. 4-1/0, split shot or 1/2 oz egg sinker, fluorocarbon leader

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.

On the table

DO NOT EAT — poisonous to eat; puffers can contain tetrodotoxin. Release carefully unharmed.
