Southern Red Snapper
The southern red snapper is the backbone of Brazil's offshore snapper fishery, particularly along the Amazon continental shelf and the Great Amazon Reef System.
Commercial fleets have worked these grounds hard for decades, but recreational and artisanal anglers also target pargo on bottom rigs over deep reef structure. It's a fish that rewards anglers willing to fish deep and stay patient.
Scientific Name: Lutjanus purpureus
Also known as Pargo, Pargo-rosa, Caribbean red snapper
- Deep, laterally compressed body with a short, rounded head and blunt snout — stockier-looking than many reef fish at the same depth.
- Overall coloration is reddish-pink to red, paler on the belly; fish from deeper water tend to run redder than those from shallower zones.
- Large eye and prominent canine teeth; vomerine teeth arranged in a chevron-shaped patch — a useful ID feature when the fish is in hand.
- Common size around 65 cm; can reach 100 cm and 10 kg, though fish that size are increasingly rare under current fishing pressure.
What to know
Habitat Distribution
- Native to the western Atlantic; in Brazil, the population is considered a single stock occupying the North Brazil Shelf, East Brazil Shelf, and South Brazil Shelf.
- A demersal species — lives and feeds on or near the bottom, typically between 70 and 120 m, though the full depth range runs from about 26 m down to 340 m.
- Strongly associated with the Great Amazon Reef System (GARS) off the mouths of the Amazon and Pará rivers — one of the most productive and heavily fished grounds for this species in Brazil.
- Also found along the northeastern coast extending toward the equatorial margin; juveniles use softer sandy or muddy bottoms before moving to harder reef structure as adults.
Key Locations
- Great Amazon Reef System (GARS) — the primary fishing ground off the mouths of the Amazon and Pará rivers; the most intensively fished area for this species in Brazil.
- Amazon continental shelf broadly — the North Brazil Shelf supports the largest concentrations and the most active commercial and artisanal fisheries.
- East Brazil Shelf — pargo are present along the northeastern coast, though fishing pressure and stock density are lower than on the Amazon shelf.
Specific Spots
- Rocky reef ledges and hard-bottom structure in 70–120 m hold the bulk of adult fish — the transition from sand to reef is where they concentrate.
- Vertical relief features like coral heads, sponge fields, and rubble piles on the Amazon shelf give pargo a place to hold against current and intercept prey moving through.
- Drop-offs at the shelf edge concentrate fish, especially where upwelling pushes cooler, nutrient-rich water up against the reef face.
Southern Red Snapper FAQ
Answers from onWater's species guide.
What are the best lures and bait for Southern Red Snapper?
Cut bait, chunks of mackerel, sardine, or squid, on a heavy bottom rig is the most widely used approach; fresh or fresh-frozen bait consistently outperforms old bait at depth.
When is the best time to fish for Southern Red Snapper?
Fishing occurs year-round along the Amazon shelf, with commercial effort largely continuous. Recreational and artisanal fishing tends to peak during calmer sea conditions, generally the drier months (July through November) when the Amazon shelf is more accessible to smaller boats.
How do you catch Southern Red Snapper?
Most fishing for pargo in Brazil is done from boats over deep reef structure, using bottom rigs with cut bait or heavy vertical jigs dropped to 70–120 m.
What do Southern Red Snapper eat?
Feeds primarily on smaller fish, squid, and crustaceans (shrimp and crabs) near the bottom, cut bait, whole small fish, and squid strips are the standard go-to baits for this reason.
Where do Southern Red Snapper live?
Native to the western Atlantic; in Brazil, the population is considered a single stock occupying the North Brazil Shelf, East Brazil Shelf, and South Brazil Shelf. A demersal species, lives and feeds on or near the bottom, typically between 70 and 120 m, though the full depth range runs from about 26 m down to 340 m.
