Saltwater · Year-round over sandy bottoms of the Cortez and mainland coast.
Bullseye Puffer
Sphoeroides annulatus
The botete diana — a common puffer of Cortez sand flats, marked by a bullseye ring on its back. Anglers catch it constantly on shrimp baits, but it must be handled and eaten with real caution (see edibility).

Where they live
How to catch them
Light sandy-bottom bait Boat
Rig: Shrimp pieces on small hooks over sand
Bait/lure: Squid strips
Key tip: Fish sand flats and lagoon mouths; puffers find baits quickly — handle with care, no bare hands on the beak.
Lagoon shore bait Shore
Rig: Small shrimp bait in estuary channels
Bait/lure: Cut bait pieces
Key tip: A frequent shore catch in mainland lagoons; unhook carefully and release unless a qualified local cook will prepare it.
Best baits & lures
Baseline setup
- Rod: Light-medium 7 ft spinning rod
- Line: 15–20 lb line
- Terminal: Size 2–1/0 hooks, small sinkers; pliers for safe unhooking
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
⚠ CAUTION: wild bullseye puffer tissues — especially liver, gonads, intestine and skin — can contain tetrodotoxin (and possibly saxitoxin), a potentially lethal poison with no antidote. Only ever eat it where an experienced local cook prepares it traditionally; otherwise release or discard — never experiment.
