Ptychidio jordani
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Ptychidio jordani faces severe population decline primarily due to extensive dam construction and water diversion projects throughout its native river systems in East Asia. Agricultural runoff and industrial pollution have significantly degraded water quality in its remaining habitat, while overfishing and destructive fishing practices have directly reduced population numbers. Climate change-induced alterations to seasonal flooding patterns have further disrupted the species' spawning cycles and juvenile recruitment.
Habitat
Ptychidio jordani inhabits large river systems and their tributaries in East Asia, preferring areas with moderate to fast-flowing water and rocky or gravel substrates. The species requires clean, well-oxygenated waters and is particularly dependent on seasonal flooding patterns for successful reproduction.
