Plectranthias bauchotae has been assessed as Least Concern. While this species is only known from eight specimens, it occurs at a depth of 120-140 m where it is unlikely to be affected by coastal development and pollution. There are no known fisheries operating within the area. The few recorded specimens is likely to be a result of inadequate sampling rather than genuine rarity.

Habitat and Ecology [top]

Habitat and Ecology: It is believed that Plectranthias bauchotae has a preference for rocky outcrop areas. It has been collected at a depth range of 140-190 m.
Systems: Marine

Threats [top]

Major Threat(s): This species is unlikely to be undergoing a rapid decline in population numbers (P.C. Heemstra pers. comm. 2009). Its preference for rocky outcrop areas protects it from fishing activity. Due to the deepwater nature of this species it is unlikely to be impacted by pollution or coastal development.

Conservation Actions [top]

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

Further surveys need to be made within this species appropriate habitat to determine level of abundance.
