Rhamdiopsis krugi

Unknown

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.

Threat summary
