Step by step, from first cast to landing.
Step-by-step: how to catch it
- Go where it lives: Rocky reefs and islands in the Gulf of California and along Pacific Baja California, south to about Mazatlán.
- Rig up: Heavy rod (80 lb class). 100–150 lb mono.
- Pick your bait: Big live mackerel and other live baits. Lures: Heavy jigs.
- Fish it: Drop a big live bait over rocky pinnacles and pull hard the moment it eats; if released, send it back down with a descending device.

- Fishing techniques
Drop a big live bait over rocky pinnacles and pull hard the moment it eats; if released, send it back down with a descending device.
- BigJoe's tip
Use a descending device so the fish survives release from deep water.
- Catch and release
Catch and release: wet your hands, keep the fish in the water when you can, and release it quickly. Use circle hooks and a dehooker.
Clean & cook

Release it.
Stay safe & legal
Safety, rules and taking care of the fishery.
- Safety warnings
Very heavy and strong; keep hands away from the gill covers.
- Regulations
Listed as endangered (IUCN) after decades of overfishing; Mexico sets rules and many skippers release them — please release every gulf grouper. Mexico requires a sport fishing license (CONAPESCA) for every person aboard a fishing boat, even those not fishing. The general daily limit is 10 fish per person, no more than 5 of one species, and only 1 billfish (marlin, sailfish or swordfish) or 2 of dorado, roosterfish, tarpon or shark. Billfish, dorado and roosterfish are reserved for sport fishing, and many islands and coasts are parks or biosphere reserves with their own rules.
- Conservation
Once common, now rare after overfishing; it was a top catch in the 1950s and '60s.
