Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2010
Date Assessed: 2009-10-09
Assessor(s): Myers, R. & Pratchett, M.
Reviewer(s): Elfes, C., Polidoro, B., Livingstone, S. & Carpenter, K.E.
Justification:
There have been declines in the abundance of Chaetodon vagabundus in some areas and research is required to understand apparent reliance on live corals. Given that this species is very widespread and typically abundant, it is unlikely that localized declines have substantially affected the global population. It is listed as Least Concern.

Geographic Range [top]

Range Description:This species is very widespread from Socotra south to Natal, South Africa across the Indo-Pacific to the Line and Gambier Islands in Polynesia, north to southern Japan and south to central New South Wales, Lord Howe and Rapa Iti (G.R. Allen pers. comm. 2006). Its geographic range is estimated to be ~76 million km2, from values estimated by Jones et al. (2002) based on projections of distribution maps from Allen et al. (1998). It is found at depth of 1-30m.

Population [top]

Population: This species is very abundant (e.g.,  mean of 1.3 individuals per 200 m2 in the northern Great Barrier Reef; Pratchett and Berumen 2008) throughout much of its geographical range. There have been slight declines in abundance recorded in Moorea, French Polynesia, between 1979 and 2003 (Berumen and Pratchett 2006), but it is otherwise stable (Pratchett et al. 2006).
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: This species occurs in most coral reef habitats, from inner coastal reef flats to outer seaward slopes. Occurs singly, in pairs, or in small groups. The diet consists of anemones, coral polyps, polychaete worms and algae. The species tolerates a wide range of ecological conditions including influx of freshwater near stream mouths and turbid water (G.R. Allen pers. comm. 2006).

This species rarely consumes coral on the Great Barrier Reef (Pratchett 2005), but does so frequently in the Seychelles (Graham et al. 2006). It has declined at Moorea between 1979 and 2003 (Berumen and Pratchett 2006), though the explanation for this is unknown, given that it is not thought to be reliant on live coral.
Systems: Marine

Use and Trade [top]

Use and Trade: This species is frequently exported through the aquarium trade (Pyle 2001).

Threats [top]

Major Threat(s): While this species has exhibited long-term declines in Moorea, there is apparent no reason why this species should depend on live coral. There do not appear to be any other major threats to this species.

Conservation Actions [top]

Conservation Actions: There appear to be no species-specific conservation measures in place. This species is present within marine protected areas. Research is required to confirm or understand the apparent reliance on live corals for this species.
