Gracila albomarginata is listed as Data Deficient. It does not form a major part of any known coral reef fishery and, very little is known of its biology or exploitation.

Geographic Range [top]

Range Description:Gracila albomarginata is an Indo-Pacific species ranging from northern Mozambique to French Polynesia, north to Okinawa (Japan), and south to the northern Great Barrier Reef (Australia). It is unknown from the Red Sea and the Persian Gulf, but has been recorded from Europa Island (in the Mozambique Channel), RĂ©union, Mauritius, Indonesia, Scott Reef and Rowley Shoals (Australia).

Population [top]

Gracila albomarginata is widely distributed and rare in most localities within its range, preferring deeper water habitat.

Fisheries-dependent and independent
Out of 17,000 serranids, only five individuals were observed in the South Pacific (IRD database). Only one specimen seen in Guam in 15 years of monitoring (creel census data) (Myers pers. comm.). A survey of 1,848 serranids over a seven month period in Pohnpei in 2006 did not find any of this species in catch in the reef fish fishery (Rhodes and Tupper 2007). The species is relatively rare on reefs in Pohnpei.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Gracila albomarginata is a reef-associated species and an active swimmer usually found on outer reef slopes and channels adjacent to deep water. It hovers above the bottom and probably feeds primarily on fishes. It is uncommon and usually solitary, however Myers (1989) reported of occasional sightings of groups of three or four fish.

Threats [top]

Major Threat(s): Gracila albomarginata may be threatened by small-scale commercial and artisinal fisheries in some areas as it is a rare species, in general. It may also be sensitive to habitat loss through coral destruction and climate change.

Conservation Actions [top]

Conservation Actions: Gracila albomarginata occurs within marine protected areas within its range, but there are no specific conservation actions for this fish.
