Black Drum

The southern black drum (Pogonias courbina) is a native inshore species with a real foothold in Argentine waters, particularly in the Río de la Plata estuary and Samborombón Bay.
Commercially harvested and recreationally fished, it's a bottom-feeding bruiser that roots around oyster beds and shell structure. Not flashy, but a legitimate target for shore and boat anglers working brackish coastal zones.
Scientific Name: Pogonias courbina
Also known as corvina negra, drum, drummer
- Stocky, deep-bodied fish with a blunt snout and a cluster of small chin barbels — the whiskers are the quickest field ID.
- Adults are dark gray to nearly black overall; juveniles show four to five bold vertical black bars on a lighter body, which can cause confusion with sheepshead — check for the barbels.
- Rounded, molar-like teeth built for crushing shellfish, not cutting bait.
- Most fish run 2–14 kg (roughly 5–30 lb); larger specimens exceeding 40 kg exist, making this the biggest member of the drum family.
What to know
Habitat Distribution
- Native to the southwestern Atlantic; in Argentina its core range centers on the Río de la Plata estuary and the semi-enclosed Samborombón Bay in Buenos Aires Province.
- A 2024 fossil study also documented the genus in Entre Ríos Province, reflecting a broader historical presence in the Paraná-Plata system.
- Prefers brackish to marine inshore waters — estuaries, coastal lagoons, and nearshore zones with soft or shell-covered bottoms.
- Larger, older fish push toward saltier, more open water near oyster beds; juveniles hold in lower-salinity areas with more cover.
Key Locations
- Samborombón Bay, Buenos Aires Province — the documented commercial and recreational hub for this species in Argentina, a semi-enclosed estuarine system.
- Río de la Plata estuary — the broader system that encompasses Samborombón Bay; inshore zones along the Buenos Aires coast hold fish year-round.
- Entre Ríos Province — the genus has been documented here, suggesting the Paraná-Plata drainage holds fish beyond the main estuary.
Specific Spots
- Oyster and shellfish beds are the single best starting point — black drum root through them the way a hog works a field.
- Channels and drop-offs inside estuaries concentrate fish as tides move water and push forage.
- Breakwaters, jetties, bridge pilings, and any hard structure in brackish water hold fish that use the edges to ambush crabs and mollusks dislodged by current.
- Shallow mudflats adjacent to deeper channels are worth working on a rising tide when fish move up to feed.
Black Drum FAQ
Answers from onWater's species guide.
What are the best lures and bait for Black Drum?
Fresh clam, mussel, and cut crab are the top natural baits, match what the fish are already eating on the bottom structure you're fishing. Soft-plastic shrimp and crab imitations on a jig head (1/4–1 oz depending on current) worked slowly along the bottom produce fish when live or cut bait isn't available.
When is the best time to fish for Black Drum?
Spring (September–November): fish become more active as water warms; good period for estuarine fishing as fish move into shallower feeding areas. Summer (December–February): peak feeding activity in inshore zones; spawning-related aggregations can concentrate fish.
How do you catch Black Drum?
Most fishing in Argentina happens from small boats working the shallow inshore zones of Samborombón Bay and the Río de la Plata, drifting or anchoring over shell bottom and running bottom rigs baited with clam or crab.
What do Black Drum eat?
Oysters, clams, mussels, and other shellfish are the staple, those crushing molars exist for a reason. Bottom rigs baited with fresh clam, mussel, or cut crab get down where the fish are feeding and match this forage directly. Crabs round out the diet, especially blue crabs and smaller shore crabs.
Where do Black Drum live?
Native to the southwestern Atlantic; in Argentina its core range centers on the Río de la Plata estuary and the semi-enclosed Samborombón Bay in Buenos Aires Province. A 2024 fossil study also documented the genus in Entre Ríos Province, reflecting a broader historical presence in the Paraná-Plata system.
