Tachysurus medianalis
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Tachysurus medianalis faces severe population decline primarily due to overfishing and habitat degradation in its limited river systems. Dam construction and water pollution from agricultural runoff have significantly altered the water quality and flow patterns essential for this catfish's survival. The species' restricted range makes it particularly vulnerable to localized threats, with fishing pressure targeting both adults and juveniles during critical breeding periods.
Habitat
This freshwater catfish inhabits medium to large river systems with moderate to fast-flowing waters, typically preferring areas with rocky or sandy substrates. The species is found in both main river channels and tributary systems, often seeking deeper pools during dry seasons and moving to shallower areas for spawning.
