Macrobrachium rodriguezi

Unknown

Overview

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

Macrobrachium rodriguezi faces severe threats from habitat degradation due to agricultural runoff and urban development in its limited freshwater range. Dam construction and water extraction for irrigation have altered natural flow regimes, disrupting the species' reproductive cycle and reducing suitable breeding habitats. Pollution from pesticides and fertilizers has degraded water quality in the streams where this endemic freshwater prawn occurs.

Threat summary

Habitat
