Lebiasina minuta

Unknown

Overview

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

Lebiasina minuta faces significant pressure from habitat degradation in its restricted range within the Orinoco River basin. Agricultural expansion and cattle ranching have led to increased sedimentation and pollution in the clear, fast-flowing streams this species requires for survival. Water extraction for irrigation and domestic use has reduced flow rates in critical breeding areas, while deforestation in surrounding watersheds has altered the natural hydrology of its habitat.
