Assessment Information
Red List Category & Criteria:
Data Deficient ver 3.1
Year Published:
2013
Date Assessed:
December 3, 2009
Justification:
Enoplometopus holthuisi has been assessed as Data Deficient. It is known from the Indo-West Pacific
and the western Indian Ocean and is found on rocky reefs at depths of 20-80 m. This is a highly prized
species in the aquarium trade industry, however no regulations are in place to manage the collection of
wild specimens. No catch data for this species is available and it is unknown if the harvesting of wild
specimens has any significant effects on its population size. Further research is required to establish its
population size and the potential effects of harvesting on this species’ populations before a more
accurate assessment of conservation status can be made.
Geographic Range
Range Description:
This species is found in the Indo-West Pacific and the western Indian Ocean (Holthuis 1983, Poupin
2003, Chan and Ng 2008). It is known from La Réunion, Indonesia, the Philippines, Enewetak Atoll in the
Marshall Islands, Austral, Society and Tuamotu Islands in French Polynesia and Hawaii (Gordon 1968,
Holthuis 1983, Chan 1998, Poupin 2003).
Country Occurrence:
Native: French Polynesia; French Southern Territories; Indonesia; Marshall Islands; Philippines; Réunion;
United States (Hawaiian Is.)
FAO Marine Fishing Areas:
Native: Indian Ocean - eastern, Indian Ocean - western, Pacific - eastern central, Pacific - western central

Population
There is no population available for this species.
Current Population Trend: Unknown
Habitat and Ecology (see Appendix for additional information)
This species inhabits rocky reef slopes and is generally found in the deeper parts of reefs at depths of
20-80 m (Chan 1998, Poupin 2003).
Systems: Marine
Use and Trade (see Appendix for additional information)
This species is collected for the aquarium trade.
Threats (see Appendix for additional information)
This is a highly prized species in the aquarium trade industry (Daum 1982, Holthuis 1983, Chan 1998,
Calado et al. 2003). Specimens are harvested from the wild for the aquarium trade (Calado et al. 2003).
However, no catch data for this species is available and it is unknown if the harvesting of wild specimens
has any significant effects on its population size.
Conservation Actions
There are no species-specific conservation measures in place for this species. Only a few countries have
implemented regulations on the collection of ornamental decapods and further research is needed to
improve our understanding of species’ reproductive biology, growth and population structure to ensure
that appropriate conservation measures can be put in place (Calado et al. 2003). There is no catch data
for this species and further research is required to establish its population size and the potential effects
of harvesting on this species’ population.
