Roestes itupiranga

Unknown

Overview

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

Roestes itupiranga faces severe pressure from hydroelectric dam construction along the Tocantins River system, which fragments its habitat and alters natural flow regimes essential for spawning. Deforestation in the surrounding Amazon basin increases sedimentation and agricultural runoff, degrading water quality in the clear-water tributaries this species requires. Mining activities upstream introduce heavy metals and other pollutants that bioaccumulate in the food chain, directly impacting this predatory fish.

Threat summary

Habitat

This species inhabits clear-water tributaries and main channels of the Tocantins River basin in Brazil, preferring areas with rocky substrates and moderate to fast-flowing water. It typically occurs in deeper pools and channel margins where it can ambush prey fish and crustaceans.
