Family:  Ostreidae (oysters)
Max. size:  20.88 cm SHL (male/unsexed); max. reported age: 4 years
Environment:  benthic; brackish; marine; depth range 0 - 300 m
Distribution:  Indo-Pacific.
Diagnosis:   
Biology:  Mainly inhabits brackish waters, wherein it occurs as thick beds in estuaries, backwaters, ports and harbors (Ref. 7693). Found in areas with somewhat reduced salinity within intertidal and shallow subtidal waters (Ref. 348). Though sporadic, it is also found on corals, rocks, hard objects or growing in bunches, on various soft bottoms to a depth of about 4 m (Refs. 101354, 53, 348 ). Feeds on diatoms, zooplankton and detritus (Ref. 107090). Also in Ref. 115735.
IUCN Red List Status: Not Evaluated (N.E.) Ref. 123251)
Threat to humans: 
Country info:  Known throughout the Philippines (Refa. 821, 75831): northern Panay, cultured in Capiz (Ref. 128042). It is produced both from wild stocks and aquaculture. From 1990 to 1995, the reported yearly production ranged from 11 800 to 18 600t. In the same period, the yearly aquaculture production ranged from around 11 700 to 18 300t. Landings from wild stocks represent only a small fraction of the total production, but the low price of harvest in areas where natural populations occur, limits development of oyster farming in those areas (Ref. 348). C: Refs. 348, 821, 75831, 128042; O: Ref. 821.
