Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

The Sailfin pimeloid faces severe pressure from overfishing throughout its Amazon basin range, where it is highly valued as a food fish and in the ornamental trade. Dam construction across major tributaries fragments populations and disrupts spawning migrations essential for reproduction. Water pollution from mining activities and agricultural runoff degrades water quality in critical breeding areas, while deforestation increases sedimentation that affects feeding grounds.

Threat summary

Habitat

This large catfish inhabits the main channels and tributaries of the Amazon and Orinoco river basins, preferring deep waters with moderate to strong currents. It occupies both whitewater and blackwater systems, moving between different river zones for feeding and spawning.
