Steindachneridion doceanum
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Steindachneridion doceanum faces severe population decline primarily due to dam construction across its native river systems in southeastern Brazil, which fragments populations and disrupts spawning migrations. Water pollution from agricultural runoff and urban development has degraded water quality in remaining habitat areas. Overfishing pressure has further reduced already fragmented populations, while habitat modification from channelization and flow regulation continues to eliminate critical breeding and feeding areas.
Habitat
This large catfish species inhabits the freshwater river systems of southeastern Brazil, particularly the Doce River basin and associated tributaries. It prefers deep pools and flowing waters with rocky or sandy substrates, requiring clean, well-oxygenated water for successful reproduction and feeding.
