Melanorivulus pinima

Declining

Overview

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

Melanorivulus pinima faces severe threats from habitat degradation in its restricted range within the Pinima River basin in Brazil. Agricultural expansion and cattle ranching have led to deforestation and sedimentation of the clear, shallow streams this killifish requires for survival. Water pollution from agricultural runoff and urban development further compromises the delicate aquatic ecosystems where this endemic species breeds and feeds.
