Africa: Lower part of Pangani River and neighbouring Zigi River in Tazania and Kenya (Ref. 2, 52331, 118630). Introduced in Mlingano dam, south of Pangani River, and probably other dams in coastal zone of Tanzania (Ref. 2, 54836). Also in Lake Rutamba, Lake Nambawala and Lake Mitupa near Lindi in southeast Tanzania (Ref. 118630, 118638).

Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय रीढ़ (सम्पूर्ण) : 16 - 18; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 9 - 11; गुदा कांटा: 3 - 4; ऐनल सौफट रेज़: 9 - 11; जानवरों की रीड़ का जोड़: 29 - 30. Diagnosis: A small bodied tilapia (Ref. 118638). About 50% of individuals have IV anal spines, the modal numbers of vertebrae (29), dorsal rays (27) and gill-rakers (15) are low, and the jaws of breeding males are enlarged (Ref. 2). Females, subadult males and juveniles with a silver/grey flank colour, light ventral colour, and characteristic melanin pattern of 7-9 broken vertical stripes on the dorsal side giving a spotted appearance; males darker, with a series of white spots/bars on the flanks; ripe males have red margins on dorsal and caudal, with a reddish tinge to the pectoral fins; males from southern populations showed a bluish sheen and less contrasting male colouration (Ref. 118638). In breeding males the throat and chest are black and broad dark vertical bars are conspicuous on the lower half of the body (Ref. 2, 4967, 54096).

जीवविज्ञान     शब्द संग्रह (उदाहरणार्थ epibenthic)

A maternal mouthbrooder (Ref. 118638). There is evidence of hybridization with native Oreochromis jipe in northern Tanzania, and non-native O. niloticus in southern Tanzania (Ref. 118638). Of only minor importance to artisanal fisheries (Ref. 118638). Maximum standard length of 18 cm (Ref. 4967) is not confirmed (Ref. 2, G.F. Turner pers. comm.); maximum total length reported as 20.8 cm (Ref. 2, 118638).
