Aulotrachichthys fernandezianus has been assessed as Least Concern. Despite the limited distribution of this species, which is restricted to two groups of islands off the coast of Chile, this species is not thought to be threatened at present. Effective habitat protection is in place throughout sections of its range, and one of the island groups it surrounds is uninhabited.

Geographic Range [top]

Range Description:Aulotrachichthys fernandezianus is restricted to the Desventuradas Islands and the Juan Fernandez Archipelago, off the coast of Chile (Pequeño and Lamillia 2000, Pequeño and Sáez 2000).  The area in which this species is distributed is approximately 460 km2.

Habitat and Ecology [top]

Habitat and Ecology:Individuals of A. fernandezianus have been captured nearshore around the Desventuradas Islands (Pequeño and Lamilla 2000). This species ranges in the photic zone from the surface, to 20 m depth.

Threats [top]

Major Threat(s): Aulotrachichthys fernandezianus has a relatively restricted distribution, which increases the possible impact of indirect and stochastic threats on its population. As an inshore species, A. fernandezianus could be impacted by threats such as pollution discharges, and is potentially at risk from the effects of increasing water temperatures resulting from global warming.  However, this species is limited to two groups of largely inaccessible islands.  One group, the Desventuradas, is uninhabited except for a military base on San Felix.  The other, Juan Fernandez, is a designated marine reserve which is considered to provide effective habitat protection (J. Moore pers. comm. 2008).

Conservation Actions [top]

Conservation Actions: There are no species-specific conservation measures in place for A. fernandezianus.  However, the distribution of this species falls within a National Park and a World Biosphere Reserve around the Juan Fernandez Islands.

Further research and monitoring is needed on the possible threats to this species..
