Brazilian Sandperch
Brazilian sandperch live along Argentina's Atlantic coast from the Buenos Aires Province shore south to Golfo Nuevo in Patagonia.
A bottom-dwelling marine fish found over sandy and rocky seafloor, it's rarely a primary target but turns up on hook and line when anglers fish deep water for other species — Charles Darwin's crew caught one off northern Patagonia in the 1830s.
Scientific Name: Pinguipes brasilianus
Also known as salmón blanco, percha de arena
- Chestnut-brown on the back with dark transverse bands across the head, flanks, and fins; white underside and pink lower lip — a distinctive color pattern noted by Darwin himself.
- Yellow irises with black pupils make the eyes stand out; useful ID feature when the fish is in hand.
- Commonly caught around 24 cm, but can reach 70 cm total length; most fish encountered by anglers run well under that maximum.
What to know
Habitat Distribution
- Native to the southwestern Atlantic; in Argentina its range runs from the Buenos Aires Province coast south to Golfo Nuevo in Patagonia.
- Demersal — lives and feeds on or near the seafloor, typically between 10 and 135 m depth over sandy and rocky bottoms.
- Research has identified distinct local populations in three Argentine zones: the Buenos Aires Province coast, San Matias Gulf (around Puerto Lobos), and Nuevo Gulf (Bahia Craker).
Key Locations
- Mar del Plata — the Buenos Aires Province coast is one of three documented Argentine population zones and the most accessible for offshore bottom fishing.
- San Matias Gulf (Puerto Lobos area) — a confirmed population zone in northern Patagonia.
- Nuevo Gulf (Bahia Craker area) — the southernmost confirmed Argentine population, near the species's southern range limit at Golfo Nuevo.
Specific Spots
- Sandy and rocky mixed bottom in 30–100 m of water is the core habitat; fish hold tight to the seafloor rather than suspending in the water column.
- Rocky reef edges adjacent to sandy flats concentrate fish — the transition between substrate types gives them both cover and access to benthic prey.
Brazilian Sandperch FAQ
Answers from onWater's species guide.
What are the best lures and bait for Brazilian Sandperch?
Natural bottom baits, cut squid, shrimp, or small crustaceans, fished directly on the seafloor on a standard bottom rig are the most practical approach given the species's invertebrate-focused diet.
When is the best time to fish for Brazilian Sandperch?
Spring and summer (September–February) coincide with the spawning period and likely the highest activity levels.
How do you catch Brazilian Sandperch?
This species is rarely targeted deliberately by sport anglers in Argentina; most catches come incidentally while bottom fishing for other species in 30–100 m of water from a boat. Fishing natural baits hard on the seafloor over mixed sandy-rocky bottom gives the best chance of an encounter.
What do Brazilian Sandperch eat?
Feeds primarily on benthic macroinvertebrates, bottom-dwelling invertebrates like crustaceans and worms. Diet composition shifts somewhat between the Buenos Aires coast, San Matias Gulf, and Nuevo Gulf populations. Natural baits fished on or near the bottom, cut squid, shrimp, or small crabs, are the logical choice.
Where do Brazilian Sandperch live?
Native to the southwestern Atlantic; in Argentina its range runs from the Buenos Aires Province coast south to Golfo Nuevo in Patagonia. Demersal, lives and feeds on or near the seafloor, typically between 10 and 135 m depth over sandy and rocky bottoms.
