Rhamdiopsis krugi
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Rhamdiopsis krugi faces significant pressure from habitat degradation in its restricted range within Brazilian river systems. Dam construction and water diversions have altered natural flow regimes critical for this catfish's reproductive cycles. Agricultural runoff and urban pollution have degraded water quality in the watersheds where this species occurs, while deforestation in surrounding areas increases sedimentation that can smother spawning substrates.
Habitat
This freshwater catfish inhabits clear, fast-flowing rivers and streams in the Atlantic Forest region of southeastern Brazil. It typically occurs in rocky substrates with moderate to strong currents, preferring areas with good water quality and adequate dissolved oxygen levels.
