Craterocephalus fluviatilis
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Craterocephalus fluviatilis faces severe population decline primarily due to habitat degradation from agricultural runoff and water extraction in its limited river systems. Introduced species, particularly exotic fish, compete for resources and alter the delicate ecosystem balance that this endemic species requires. Dam construction and water diversions have fragmented populations and reduced water quality in critical breeding areas.
Habitat
This species inhabits clear, flowing freshwater streams and rivers with rocky or sandy substrates in southeastern Australia. It requires well-oxygenated waters with stable temperatures and minimal siltation for successful reproduction and feeding.
