Lutjanus griseus
Mangrove Snapper (Lutjanus griseus), also widely known as Gray Snapper, is one of the most abundant, versatile, and popular sport fish in Florida. Found from shallow mangrove-lined creeks and dock pilings to deep offshore reefs and wrecks, mangrove snapper are available to virtually every Florida angler regardless of boat size or budget. They are known for being extremely cunning and leader-shy — a challenge that makes them a favorite target among experienced anglers. Mangrove snapper school tight to structure, making them predictable but demanding precise, finesse presentations. Their mild, sweet white flesh makes them one of the best-eating fish in the state. Florida waters hold mangrove snapper from Key West to the Panhandle, with concentrations highest in South Florida, the Keys, and Southwest Florida.

Mangrove snapper are available year-round in Florida. Inshore fishing peaks in late spring through summer (May–September) when fish move shallow to feed aggressively around mangroves, docks, and bridges. Offshore fishing peaks in summer and fall. Night fishing under dock lights and bridge lights is excellent from June through October. In winter, fish move slightly deeper and become more lethargic, but are still catchable around warm-water discharge areas and deeper structure.
Light fluorocarbon leader is critical — 15–20lb max inshore, 30lb offshore. Use a 1/0 to 2/0 hook with live shrimp, small pilchards, or cut threadfin herring. Drop-shot rigs and free-lined baits work well inshore. At night under dock lights, let live shrimp drift naturally on the current edge. Offshore, chum aggressively with cut sardines or pilchards and present live bait in the chum slick. A steady chum slick raises fish off the reef dramatically. Jig fishing with small paddle-tail soft plastics (1/4oz) on light fluorocarbon also works well. Use the minimum weight needed — snapper detect resistance and drop the bait instantly.
10 inch minimum total length. 10 fish per angler per day in state waters (within 9 miles Gulf, 3 miles Atlantic). Federal waters have separate limits — verify at myfwc.com and fisheries.noaa.gov before your trip. No closed season inshore. Offshore federal seasons apply.
Use as light a fluorocarbon leader as conditions allow — 15lb inshore, 20–30lb offshore. Snapper inspect the bait before committing — any unnatural presentation gets refused. Night fishing under dock lights is incredibly productive from June through September. Look for fish suspended under lights and present a live shrimp or small jig at their level. Always anchor upcurrent of a reef offshore and let your chum slick drift over the structure.

They are the same fish. Mangrove snapper (Lutjanus griseus) is commonly called gray snapper in offshore and South Florida contexts, and mangrove snapper in inshore contexts. Both names refer to the same species.
Live shrimp on a 1/0 circle hook with minimal weight is the most reliable bait. Small live pilchards, cut threadfin herring, and live pinfish also work. Offshore, a steady chum slick with live bait fished inside the chum is the go-to technique.
Late spring through early fall (May–September) is peak season inshore. Night fishing under dock lights from June through October is outstanding. Offshore, summer and fall produce the best results.
Inshore fish average 1–2 pounds. Offshore mangrove snapper regularly reach 3–5 pounds, with trophy fish exceeding 8–10 pounds. The Florida record is 17 pounds. Fish over 15 inches are considered large specimens.
Yes — mangrove snapper (gray snapper) are among the best-eating fish in Florida. Their mild, sweet white flesh is firm and versatile — excellent grilled, fried, blackened, or in ceviche. They are considered a premium table fish.
Mangrove snapper are found around virtually any hard structure with water over 60°F — dock pilings, bridge fenders, mangrove roots, jetties, artificial reefs, and natural offshore reefs. The Florida Keys, Southwest Florida, and Tampa Bay are top inshore destinations. Offshore, any natural or artificial reef in 40–120 feet holds snapper.
