Mangrove Red Snapper
Lutjanus argentimaculatus
Mangrove Red Snapper (Lutjanus argentimaculatus) is a brackish-to-marine snapper found around mangroves, estuaries, reefs, and river mouths across the Indo-Pacific. It is a strong predator that often moves into freshwater reaches in some regions and is prized by anglers.

Identification points
- Reddish to copper body with a paler belly
- Prominent dark blotch/stripe near the operculum and sometimes a faint yellowish side spot pattern
- Large snapper shape with a steep forehead and a relatively blunt head
Habitat
Mangrove roots, tidal creeks, estuaries, muddy river mouths, lagoons, and nearby reefs; juveniles often use sheltered brackish habitat, while adults also frequent coastal structure and occasionally upstream freshwater in tropical rivers.
Bait notes
Live bait such as mullet, sardines, prawns, and small crabs is highly effective; cut bait also works well. Jigs, soft plastics, and small metal lures can take fish around structure when worked close to cover.
Behavior
An ambush predator that feeds on মাছ, shrimp, crabs, and other crustaceans, especially at dusk, night, and during moving tide. It holds tight to cover and is often more active around tidal flow and low light.
Caution
Sharp gill covers and teeth can cut hands; use a lip grip or pliers. Flesh is generally good to eat, but larger reef-associated fish may carry some ciguatera risk in certain areas, so follow local advisories.
Fishing notes
Fish close to mangrove edges, fallen timber, bridge pylons, and current lines with a heavy enough leader to handle abrasion. Use precise casts, let bait sink naturally, and set hard to turn fish away from cover quickly.
