Macrobrachium oxyphilus

Unknown

Overview

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

Macrobrachium oxyphilus faces severe population decline primarily due to habitat degradation from agricultural runoff and urban development in its limited freshwater range. Dam construction and water extraction have altered natural flow regimes essential for this freshwater prawn's reproductive cycle. Pollution from pesticides and industrial discharge has contaminated the clean, well-oxygenated waters this species requires for survival.
