Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2010

This species is widespread throughout the Indo-Pacific and is the largest of the butterflyfishes. It is collected for the aquarium trade and captured in artisanal fisheries. However these are not thought to be causing substantial declines to the global population.This species also appears to be reliant on live corals for recruitment. Further research is recommended into this aspect of its biology. This species is listed as Least Concern.

Geographic Range [top]

Range Description:This species is widely distributed throughout the Indo-Pacific, from the East African coast and the Red Sea in the west to Polynesia, including the Hawaiian Islands (USA),  from southern Japan in the north to southern New South Wales and Lord Howe Island (Australia) in the south (G.R. Allen pers. comm. 2006). It is found at depths of 2-171 m.

Very widespread: Range size ~78.6 million km2, from values estimated by Jones et al. (2002) based on projection of distribution maps from Allen et al. (1998).

Population [top]

Population:This species is generally common. It settles in areas of rich coral growth (Pratchett et al. 2008), but there have not been any documented declines in its abundance.
Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is generally associated with coral-rich areas of lagoons and seaward reefs. It usually occurs in pairs, but solitary individuals and small aggregations are sometimes encountered (G.R. Allen pers. comm. 2006). This species does occasionally feed on coral, but mostly consumes non-coral sessile invertebrates, such as Spirobranchus, zooanthids and clams (Pratchett 2005). Recruits have been found in areas with rich coral growth, but their reliance on live coral is currently unknown. This is the largest of all butterflyfishes, and there are unpublished reports that it may live >50 years. Because it is very long-lived, effects of recruitment failure may not be apparent for decades after coral depletion.

Use and Trade [top]

Use and Trade: This species is frequently exported through the aquarium trade (Pyle 2001). This species is targeted by artisanal fisheries in some parts of its range (Lawton et al. in review).

Threats [top]

Major Threat(s): This species has been seen to recruit to live coral, but there have been no documented declines in abundance associated with extensive coral depletion (Pratchett et al. 2008). Adults are associated with coral reef habitats but do not rely on live coral for food. Because it is very long-lived, effects of recruitment failure may not be apparent for decades after coral depletion. There is no data on effects of aquarium collections on this species. It is also targeted by artisanal fishers, however this is not thought to be a major threat. There do not appear to any other major threats to this species.

Conservation Actions [top]

Conservation Actions: There are no species-specific conservation measures in place for Chaetodon lineolatus. This species is present within marine protected areas. Ongoing monitoring of catches by aquarium collectors is required. Research is required to confirm or understand the apparent reliance on live corals for this species.
