简单描述
型态特徵 | 形态测量图
背棘 (总数): 15 - 18; 背的软条 (总数): 11-14; 臀棘 3; 臀鳍软条: 9 - 12; 脊椎骨: 29 - 30. Diagnosis: A large, deep-bodied species; mature males develop enlarged jaws and a concave head profile (Ref. 2, 118638). Other distinguishing characters of this species include: vertebrae 29-30; dorsal spines XV-XVIII, total dorsal rays 27-30, anal spines III; lower gill rakers 19-27; pharyngeal teeth slender, but firm, not crowded, blade of lower bone 0.9-1.25 times length of dentigerous area; and depth of caudal peduncle greater than its length (Ref. 2). Freshly collected males vary in colour: sometimes with grey head, brownish-golden upper parts, or sometimes with pinkish unpaired fins and upper parts; under stress, or after death, males tend towards uniform black body and fins, with reddish-pink dorsal and tail fin margins; females and immatures vary from light grey to dark brownish background, with dark flank patches and an anal fin with faint vertical bars (Ref. 2, 118638).
成熟雄性的颚增大了; 轮廓凹曲。 雌性与非繁殖期的雄性银色的或铁-灰色的通常有 2-4 侧面中央的斑块与比较背部的系列显着的。 繁殖期的雄性通常深色的橄榄色到黑色的, 与背鳍与边缘的边缘或上半部尾部的鲜红色,粉红的或橘色的。 深的眶前骨。 成鱼尾鳍有密集的鳞片形状
A maternal mouthbrooder (Ref. 118638); oviparous (Ref. 205). A large, fast-growing species heavily exploited in its native range (Ref. 118638). It was globally cultured in the past, making use of its salt tolerance and ability to produce all-male strains through hybridisation with Oreochromis niloticus and O. mossambicus (Ref. 118638).
