Scientific Name: Choerodon gomoni
Species Authority: Allen & Randall, 2002

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2010
Date Assessed: 2008-06-12
Assessor(s): Shea, S. & Liu, M.
Reviewer(s): Sadovy, Y. & Carpenter, K.E.
Justification:
This species is only known from a few locations in the western Pacific. Although little is known about its population status, habitat requirement, reproduction, recruitment, life history, or ecology, it is a deep water species and there are no known threats. It is listed as Least Concern.

Geographic Range [top]

Range Description: This species is only known from four locations in the Western Central Pacific: Banggai Islands and Togean Island, Indonesia, Checkfield Bank, New Caledonia, and the Great Barrier Reef, Australia (Allen and Adrim 2003, Cappo et al. 2007, Speare and Stowar 2007). As this species is found in deeper waters, it is not well-known, but its distribution is likely wider than these three locations.

Population [top]

Population: There is no population information available for this species. It is a deeper water species, and has not been commonly observed.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: This species is demersal and has been recorded at a depth of 30-82 m (Bogutskaya 2007). There is no information on this species habitat requirements, biology or ecology. The maximum size of this species is 10.3 cm SL (Randall 1997).
Systems: Marine

Threats [top]

Major Threat(s): There are no major threats known to this species. Although this species was observed in an underwater biodiversity survey and was identified as being susceptible to trawling given its depth and habitat association in the Great Barrer Reef (Pitcher et al. 2007), it is probably not threatened in many areas of Australia due to the depth (to 82 m) of its occurrence (Bogutskaya 2007) and the maximum size of this species recorded at 10.3 cm SL (Randall 1997), which means it does not the current minimum legal capture size of 40 cm in many areas of Australia (Queensland Government, Government of Western Australia 2008, 2008a).

Conservation Actions [top]

Conservation Actions: This species is observed in the Great Barrier Reef Marine Park through baited underwater video surveys (Cappo et al. 2007, Speare and Stowar 2007).

In Queensland, the minimum legal size for tuskfish (Choerodon spp.) is 30 cm and daily bag limit is five in total for all Choerodon species per angler, in addition, closed season for fishing applies to coral reef finfish (Queensland Government).

This species is poorly known, as it occurs in deeper waters and has not been well-studied. More information is needed on its distribution, population status, habitat requirements, biology, ecology, and major threats.
