How to catch Flatwhiskered catfish
Pinirampus pirinampu (Spix & Agassiz, 1829)
About Flatwhiskered catfish fishing
Pinirampus pirinampu is a streamlined freshwater catfish belonging to the family Pimelodidae, distinguished by its elongated, flat barbels and torpedo-shaped body. Growing up to a maximum length of 120 cm, this demersal species natively inhabits major South American river networks including the Amazon, Orinoco, and Paraná basins. It functions as a nonspecialist carnivore, gathering in schools and actively preying upon various benthic organisms and smaller fish. Known to undertake potamodromous spawning migrations upstream at the start of the rainy season, it is highly valued by commercial and sport fishers alike for its powerful fighting traits and palatable flesh.

When to fish for Flatwhiskered catfish
How to catch Flatwhiskered catfish
Tips for catching Flatwhiskered catfish
To target this schooling catfish successfully, focus efforts around deep river channels, reservoirs, and structural drop-offs where current breaks provide shelter. Bottom fishing with heavy ledger rigs baited with fresh cut fish or whole dead baits yields consistent results, mimicking their natural diet of benthic prey and small fish. Live baiting near the bottom during twilight hours can also provoke strikes from larger specimens. When water levels rise and fish become active during their upstream migratory phases, presenting large spoons or deep-diving lures via spinning gear around converging currents offers an effective alternative approach.
