Melanorivulus salmonicaudus

Unknown

Overview

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

Melanorivulus salmonicaudus faces severe pressure from agricultural expansion and cattle ranching activities that degrade its freshwater habitats in the Brazilian Cerrado. Urban development and water extraction for irrigation further fragment the small streams and seasonal pools this species depends upon. Pollution from agricultural runoff introduces pesticides and fertilizers that alter water chemistry and reduce prey availability.

Threat summary
