Etymology: Acanthopagrus: Greek, akantha = thorn + Greek, pagros, a kind of fish (Ref. 45335); berda: Name refers to the local vernacular name for the species; noun in apposition (Ref. 83673).

морской; пресноводный; солоноватоводный демерсальный; мигрирует в океане (Ref. 51243); пределы глубины ? - 50 m (Ref. 86942). Tropical; 30°N - 35°S, 22°E - 103°E
Indian Ocean, South Africa, Mozambique, the Red Sea, Persian Gulf, India, Phuket (Andaman Sea, specimen lost), and Malaysia (Penang Island and Langkawi Island, near Singapore). Western Pacific specimens recorded as A. berda refer to Acanthopagrus pacificus (Ref. 86288).

Max length : 90.0 cm TL самец/пол неопределен; (Ref. 3198); common length : 35.0 cm TL самец/пол неопределен; (Ref. 5450); наибольший вес (опубликованные данные): 3.2 kg (Ref. 3670); наибольший возраст (опубликованны данные): 14 годы (Ref. 3627)
колючие лучи спинного плавника (общее число) : 11 - 12; членистые (мягкие) лучи спинного плавника (общее число) : 10 - 13; колючие лучи анального плавника: 3; членистые (мягкие) лучи анального плавника: 8 - 9. Diagnosis: This species is distinguished from all its congeners by the following characters: scale rows between fifth dorsal-fin spine base and lateral line 3.5; front edge of dorsal scaly area on head slightly convex, with small scales (fewer than 20) anteriorly; pored lateral-line scales 42-44; second anal-fin spine (2AS) longer than third anal-fin spine (3AS), 2AS/3AS ratio 1.23-1.50 (mean 1.36); strongly curved concavity on ventral edge of first two infraorbitals above rear end of maxilla, particularly obvious in specimens more than 13 cm standard length; scales on preopercle flange absent; anal-fin membrane dark; molariform teeth strongly developed along both jaws, teeth rows strongly curved laterally at rear of lower jaw (Ref. 83673).
Body shape (shape guide): short and / or deep; Cross section: compressed.
Common in estuaries, relatively uncommon in freshwaters (Ref. 52193). It feeds on invertebrates, including worms, mollusks, crustaceans and echinoderms (Ref. 5213), and small fish (Ref. 3670, 52193). Breeds in winter at sea (Ref. 52193). Protandrous hermaphrodite (Ref. 55367). The flesh is excellent; sold fresh in markets. It is parasitised by the monogenean Anoplodiscus australis on the fins and body surface (Ref. 124057).
Size at sex change = 19.1 TL; age at sex change = 1.95 years (Ref. 55367).
