Steindachneridion doceanum

Declining

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.

Threat summary

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.

Frequently asked questions

Why is Steindachneridion doceanum classified as Endangered?
Steindachneridion doceanum is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. 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.
Where does Steindachneridion doceanum live?
Steindachneridion doceanum occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Steindachneridion doceanum?
The main threats to Steindachneridion doceanum are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
