Nassau Grouper
Epinephelus striatus
Nassau Grouper (Epinephelus striatus) is a large Atlantic reef grouper best known for forming predictable spawning aggregations. It has steeply declined across much of its range from overfishing, and is protected or heavily regulated in many areas.
Identification points
- Tan to olive body with 5 dark, narrow vertical bars
- Distinct dark saddle-like blotch on top of the caudal peduncle
- Three spines on the gill cover, with a relatively large grouper head and mouth
Habitat
Coral reefs, reef drop-offs, rocky ledges, and lagoon and patch-reef edges from shallow water to about 100 m; adults often move to specific offshore spawning sites.
Bait notes
Best on fresh-cut bait, live pilchards, pinfish, grunts, herrings, squid, and other small reef fish. Large soft plastics and jigs can work, but bait is usually more reliable.
Behavior
A sedentary ambush predator that feeds mainly at dusk and night on fish and crustaceans. It is strongly site-faithful and migrates to traditional spawning aggregations, making it highly vulnerable to targeted fishing.
Caution
Many stocks are depleted and the species is protected or tightly regulated in numerous Caribbean countries and U.S. waters; verify local rules before targeting or keeping one. Large reef predators may also carry ciguatera risk in some areas.
Fishing notes
Fish near reef edges, cuts, and holes with heavy tackle and abrasion-resistant leader; keep fish out of structure fast. Night fishing and fishing around known aggregation sites are often effective, but check local closures and seasons.
