Habitat and Ecology [top]

Habitat and Ecology:Epinephelus chlorocephalus is a demersal species, but nothing is known of its habitat and biology. The absence of additional specimens is puzzling. The only specimen currently in collection was obtained from locals from Tongatapu by J. Quoy and P. Gaimard during the expedition of J. Dumont d'Urville, 1826-1829.

Use and Trade [top]

Use and Trade: The use and level of consumption for this species is unknown. If harvested, this species is assumed to be taken whole. There is probably no trade of this species, i.e. if harvested, it is probably intended solely for subsistence purposes.

Threats [top]

Major Threat(s): Owing to the lack of life history, population and fisheries data, no major threats can be established for Epinephelus chlorocephalus.
