Scientific Name: Epinephelus melanostigma Schultz, 1953

Epinephelus melanostigma Schultz, 1953
Taxonomic Notes: Epinephelus melanostigma is one of the “reticulated groupers” which comprise nine shallow water coral reef species that have a rounded caudal fin and close-set dark brown spots, with pale interspaces forming a network on the body. These species have been much confused in the literature (Heemstra and Randall 1993).

Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2008
Date Assessed: 2008-01-01
Assessor(s): Russell, B., Rhodes, K., Myers, R., Heemstra, P.C. & Kulbicki, M.
Reviewer(s): Sadovy, Y. & Moss, K. (Grouper and Wrasse Red List Authority)
Epinephelus melanostigma is listed as Data Deficient owing to confusion in records of other serranids in the hexagonatus complex. The species is likely a minor component of both artisinal and live reef food fisheries.

Population [top]

Population:Little known about its population or abundance, probably because Epinephelus melanostigma is a member of the reticulated (hexagonatus) grouper complex and easily confused with other species. It is not commonly observed. It constituted less than 2% of catch in reef fish fisheries in Pohnpei in 2006 (Rhodes and Tupper 2007).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:General
Epinephelus melanostigma is a coral reef-associated species occurring in outer reef flats and shallow lagoons (Myers 1999), reportedly in depths less than 7 m (Heemstra and Randall 1993) although also reported to occur in reefs at a depth of about 30 m (Fischer et al. 1990) and has appeared in trawls (Gloerfelt-Tarp and Kailola 1984). Its maximum size is reported to be 35.0 cm TL (Kuiter and Tonozuka 2001). There are reports of ciguatera poisoning for this species (Dalzell 1991).

Feeds on fishes and benthic crustaceans (Masuda and Allen 1993).

Threats [top]

Major Threat(s): Epinephelus melanostigma is found in subsistence fisheries, but because of its small size and apparent rarity, it is of little or no commercial importance. Habitat degradation (coral loss) may also impact this species.

Conservation Actions [top]

Conservation Actions: Epinephelus melanostigma occurs in marine protected areas within its range, but there are no specific measures for the species.
