Lophiobrycon weitzmani

Unknown

Overview

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

Lophiobrycon weitzmani faces severe threats from deforestation and agricultural expansion in Brazil's Atlantic Forest region, which has reduced its freshwater habitat to fragmented remnants. Water pollution from agricultural runoff and urban development further degrades the clear, fast-flowing streams this species requires. The construction of small dams and water diversions for irrigation has altered natural flow patterns in many of its remaining habitats.
