Africa: most of the Rufiji River and its tributaries, Kingani [= Ruvu] River, Mbwenkuru River and Wami River, all in Tanzania (Ref. 2, 118630, 118638). Populations in Zanzibar and Pemba may be native, although there may also have been some stocking from the mainland (Ref. 118638).
非洲: Rufigi 河與它的支流; Kilombero 與大的 Ruaha 河, 但是不在三角州中; Kingani 與 Mbenkuru 河, 所有的在坦尚尼亞。

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

生物学特性     字汇 (例如 epibenthic)

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).
