Epinephelus areolatus is a widespread species that is relatively common. However, in some areas (e.g., Hong Kong, mainland China) the species has shown notable declines directly related to fishing pressure, primarily trawling. Because this is not one of the major target species, in addition to the restrictions on trawling within many areas of its range, it is currently considered a Least Concern species.
Epinephelus areolatus is a very widespread Indo-Pacific species that ranges from the Red Sea and the Persian Gulf to Natal (South Africa), east to Fiji, north to Japan, and south to the Arafura Sea (Russell and Houston 1989) and northern Australia. Recently it has been recorded from Tonga (Randall et al. 2003). Areolate grouper appears to be absent from Micronesia, Polynesia, and most islands of the western Indian Ocean (Randall and Heemstra 1991). It is often confused with Epinephelus chlorostigma.

Epinephelus areolatus is widespread and reasonably common, relatively common in some areas, but details of its current population abundance are unknown. However, it is likely declining due to intensive fishing efforts over soft bottoms (i.e. trawling) throughout much of its range.
Areolate grouper are reported catch from Saudi Arabia, but statistics do not indicate a decline (2000 to 2004) (http://www.fao.org).
Epinephelus areolatus is one of the most common grouper species on soft bottoms in New Caledonia (8.0% of grouper catch). Experimental fishing within a 10 year interval resulted in a 50% decline in catch (IRD database). Reported mean size 30 to 35 cm TL, with a density of 0.013/100 m sq. in New Caledonia (SPC PROCFISH data 2005).
A once common species in Hong Kong, but now rare, as a result of intensive trawling (Sadovy and Cornish 2000).
Small-scale industrial and commercial line and trap catch (Mozambique) represents 0.5 to 1% of the total catch (unpub. Data: FRI-Maputo). Second-most commonly caught serranid captured in Djibouti commercial fisheries (Darar 1984).
|Habitat and Ecology:||
Epinephelus areolatus is found usually in turbid water in seagrass beds or silty sand bottoms around isolated small rock outcrops, dead coral or soft coral (Randall and Heemstra 1991) in shallow continental shelf waters (Leis 1987) in depths from 2 to 200 m (Randall and Ben-Tuvia 1983, IRD database). Juveniles are common at water depths to 80 m (Kailola et al. 1993).
Feed on fish and benthic invertebrates, primarily prawns and crabs (Kulbicki et al. 2005, Randall and Heemstra 1991, Parrish 1987, Salini et al. 1994).
Size and age
Maximum size is reported to be 47.0 cm TL, with a maximum weight of 1.4 kg (Moran et al. 1988). The maximum reported age for areolate grouper is 15 years (Shapiro 1987).
Areolate grouper probably spawns during restricted periods and forms aggregations when doing so (Shapiro 1987).
In New Caledonia, the sex ratio is reported as 1:6 males to females, with a size at maturity of females at 19.5 cm TL and 29 cm TL for males (IRD database).
Epinephelus areolatus is subject to commercial and recreational fishing activities, including the live reef fish trade (Philippines) (Pratt et al. 2000, Padilla et al. 2003) and the marine aquarium fish trade, have the potential to adversely affect populations of this species.
A trawl species in N. Australia (Errity 2003) and forms part of by-catch of the Northern Prawn Fishery in Australia (Stobutzki et al. (2001). Reported catch (tonnes) for Saudi Arabia (FAO unpublished) for 2000 (306), 2001 (245), 2002 (289), 2003 (309), 2004 (349) does not indicate any decline in this fishery. Not significantly caught by handline but major component of serranid long-line catch in New Caledonia (Kulbicki et al. 2000). A 50% decline of catch in the experimental longline fishing in southern New Caledonia (IRD database).
One of the most common mariculture species in southern China SE Asia and the Middle East (Leung et al. 1999). Live reef fish import data from the Hong Kong Census and Statistics Department (HK CSD) record the largest quantities of "other groupers" and "other marine fishes" as being imported from Thailand. Thailand and Malaysia are important sources for so-called "cultured" species including brown-spotted groupers Epinephelus areolatus / E. bleekeri, which are amongst 12 most commonly available species imported to Hong Kong (http://www.traffic.org/reef-fish/executivesummary.html). Fingerlings are wild-caught in Vietnam and Thailand (Sadovy 2000) and no hatcheries are known for this species (Sadovy pers. comm.).
Areolate grouper occurs in marine protected areas within its range.
Epinephelus areolatus is listed as ‘Least Concern’ in NT Australia. There is a 35 cm minimum size limit and bag limit five fish (mixed species) in Queensland Australia (Department of Primary Industries 2003).
