Justification:
Earle's Splitfin (Luzonichthys earlei) has been assessed as Least Concern. This is a wide-ranging species with no known major threats at present. Although this species may be locally affected by habitat degradation in the form of coral bleaching, and is also occasionally collected for the aquarium trade, these threats are not thought to be causing any significant population declines at present. Monitoring of the habitat status and harvest levels of this species is needed in case these threats intensify in the future.

Threats [top]

Major Threat(s): Earle's Splitfin is potentially impacted by habitat degradation and bleaching events on reef systems (Kelty and Kuartei 2004, NCCO 2005). This species is also occasionally collected for the aquarium trade. However, these are localized threats only, and therefore presently do not represent major threats to this species.

Conservation Actions [top]

Conservation Actions: There are no known species-specific conservation measures in place for Earle's Splitfin, however its distribution may cover a number of marine protected area designations, including the Hanauma Bay Marine Life Conservation District in the Hawaiian Islands.

Monitoring of the habitat status and harvest levels of this species are needed.
