Saltwater · Year-round on deep reefs; peak June to August around summer full-moon spawning aggregations — heavily protected in places, check current rules
Cubera Snapper
Lutjanus cyanopterus
The largest snapper in the western Atlantic, a grey-brown giant that can pass 100 lb (45 kg) with huge canine teeth and thick lips. It is a separate species from the Pacific cubera (Lutjanus novemfasciatus) of the eastern Pacific — the two are close relatives, not the same fish. Adults gather on deep reefs and spawn in summer full-moon aggregations that are heavily protected in places, so check current rules before targeting them; very large fish also carry a ciguatera caution.
Seasons · Peak
Identifying features
- Uniform grey to reddish-brown body, darkening on large adults
- Huge canine teeth, visible even when the mouth is closed
- Very thick lips and a broad, heavy head
- Triangular patch of teeth on the roof of the mouth (vomer), unlike the anchor-shaped patch of gray snapper
- Massive size — by far the largest western Atlantic snapper, over 100 lb (45 kg) at maximum
Habits
- Solitary adults hold on deep reefs, wrecks and ledges by day
- Feeds at night on fish, crabs, shrimp and lobster
- Forms large summer spawning aggregations over deep reef around the full moon
- Juveniles live inshore in mangroves and seagrass before moving offshore
- Powerful and structure-bound — a hooked fish dives hard for the reef
Distribution
Where to find them
- Deep reefs and wrecks off the Florida Keys in summer
- Offshore ledges along Florida's Atlantic coast
- Deep Gulf structure off Louisiana, only occasionally
Where they live
How to catch them
Live lobster or large crabs on heavy bottom tackle Boat
Rig: Heavy conventional tackle, 80-100 lb leader and a large circle hook with a live lobster or crab, fished on the bottom over reefs during summer spawning aggregations where rules allow
Bait/lure: Live lobster and large crabs
Key tip: Fish heavy and stop the first run — a big cubera that reaches the reef almost always wins; check seasonal protection rules before any aggregation trip.
Heavy live-baiting at night over structure Boat
Rig: Large live baitfish on heavy spinning or conventional tackle with a stout leader, soaked at night over wrecks and deep ledges
Bait/lure: Blue runners and other big live baitfish
Key tip: Cubera feed boldly after dark — keep baits just off the bottom and the drag locked down tight.

On the table
Good in smaller fish; very large fish carry a ciguatera caution and are best released — and spawning aggregations are protected in places, so check rules.
