Sparidae (Porgies)
Etymology: Acanthopagrus: Greek, akantha = thorn + Greek, pagros, a kind of fish (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
生態学
海; 新鮮な水; 汽水性の 底生の. Subtropical; 23°S - 44°S, 112°E - 154°E
Indo-Pacific: endemic to southern Australia.
Length at first maturity / サイズ / 重さ / 年齢
Maturity: Lm ?, range 16 - ? cm
Max length : 60.0 cm TL オス/雌雄の選別がない; (Ref. 2156); common length : 24.0 cm TL オス/雌雄の選別がない; (Ref. 2156); 最大公表体重: 4.0 kg (Ref. 26523); 最大記録サイズ: 29 年 (Ref. 36820)
背面の脊椎 (合計) : 10 - 13; 背鰭 (合計) : 10 - 13; 肛門の骨: 3; 臀鰭: 8 - 10. The upper body can vary from silvery to golden brown, bronze, green or black depending on habitat. Chin and belly are usually white and fins are dusky to greenish black. Dorsal and ventral profiles of adults are similarly convex.
Endemic in coastal areas, rivers and estuaries of Australia. Most abundant in river mouths and estuaries (Ref. 28468, 28472). Inhabit brackish waters of coastal rivers and lakes, occasionally penetrating fresh water (Ref. 44894). Considered as the only true estuarine sparid in Australia. Larvae and small juveniles are most abundant over seagrass beds in shallow estuarine waters (Ref. 28468, 28472). Spawning period varies considerably between estuaries (Ref. 28468). Remain upstream in sheltered waters to spawn and is not usually found in purely marine habitats (Ref. 44894). Feed on shellfish, worms, crustaceans, small fish and algae. Sold as whole, chilled products in domestic markets (Ref. 6390). One of top angling species in southern Australia (Ref. 6390, 44894), as well as being a delicious table fish (Ref. 2156).
It is not known whether there is any sex inversion in black bream (Ref. 6390).
