Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-01-01
Assessor(s): Cabanban, A.S. & Sadovy, Y.
Reviewer(s): Sadovy, Y. & Moss, K. (Grouper and Wrasse Red List Authority)
Epinephelus miliaris is evaluated as a species of Least Concern because it is widespread and there is no evidence to support a decline of >30 %. However, if its coastal habitats (mangrove forests, seagrass beds, bays, and coral reefs) continue to be destroyed, its conservation status will worsen.

Population [top]

Population:Epinephelus miliaris is typically found in low densities. Fry et al. (2006) caught only four individuals (mean SL = 320 mm ±37; mean weight 835 ±258 g) in an undisturbed volcanic seamount reef, Lihir Island Group, Papua New Guinea.
Current Population Trend:Unknown

Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:General
Epinephelus miliaris is a reef-associated species found in a variety of habitats. Juveniles (8 to 21 cm SL) have been taken from mud bottoms, seagrass beds, mangrove swamps, and from coral reefs in depths of 1 to 16 m; adults in coral reefs at depths of 18 to 180 m.

Stomach contents reported to include juvenile clappid crab, a stomatopod, and a gastropod (Morgans 1982).

Threats [top]

Major Threat(s): Epinephelus miliaris is threatened by overfishing and is taken by subsistence and incidental fisheries. Destruction of habitats is also a concern, including loss of mangrove forests, trawling on bays (soft-bottom environment), reclamation of seagrass beds and sedimentation and fish-bombing on coral reefs.

Conservation Actions [top]

Conservation Actions: Epinephelus miliaris is found in marine protected areas in parts of its range.
