Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2010
Date Assessed: 2009-02-04
Assessor(s): Heemstra, P.C. & Sadovy, Y.J.

Plectranthias bilaticlavia has been assessed as Least Concern.While this species is only known from eight specimens, its preference for rocky reef habitats is likely to protect it from fishing activity within the area. Its deepwater nature is likely to protect it from coastal development or pollution. The few recorded specimens are likely to be a result of poor sampling effort. Further surveys need to be made within appropriate habitat to determine abundance for this species.

Population [top]

Population:Plectranthias bilaticlavia is thought to be known from only a few specimens which may be a result of poor of sampling effort (P.C. Heemstra pers. comm. 2009).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:Unknown

Habitat and Ecology [top]

Habitat and Ecology:Plectranthias bilaticlavia is a demersal species found on rocky reefs at a depth range of 164-270 m. It is found within the continental shelf. This species is likely to be found solitary or in small groups (P.C. Heemstra pers. comm. 2009).

Threats [top]

Major Threat(s): As this species is known from deep water rocky reefs it is unlikely to be taken by trawler fisheries operating within this area. Coastal development and pollution are also of no major concern.

Conservation Actions [top]

Conservation Actions: There are no species-specific conservation measures in place for Plectranthias bilaticlavia.

Further surveys are needed to determine the abundance of this species.

Errata [top]

Errata reason: This errata assessment has been created because the map was accidentally left out of the version published previously.
