Africa: Two subspecies are recognized: Oreochromis shiranus shiranus from Shiré River above the Murchison rapids and Lake Malawi, together with their tributaries in Tanzania, Malawi and Mozambique (Ref. 5166, 118630); Oreochromis shiranus chilwae from Lake Chilwa and its basin in Malawi and Mozambique (Ref. 5166, 118638).

توصيف مختصر ريخت شناسي | ريخت ستجي بوسيله انداره گيري

خارهاي باله پشتي (کل): 15 - 18; شعاع نرم باله پشتي (کل): 10-13; خارهاي باله مخرجي 3-5; شعاع نرم باله مخرجي: 9 - 11; مهره ها: 29 - 30. Diagnosis: A large, deep-bodied species with 4, rarely 3 or 5, anal fin spines (Ref. 118638). Females and immatures from the Lake Malawi catchment have a dark olive-coloured body, yellow-gold below; other populations, such as those from Lakes Chilwa and Chiuta and the Ruvuma system show a more silvery colour; unusually for Oreochromis, the horizontal stripes are often more prominent than the vertical bars; adult males develop very large jaws and a concave head profile, they are black, with red margins to the dorsal and caudal fins (Ref. 118638). Underwater or in aquaria, males show numerous white spots on the upper half of the flanks, but these fade quickly under stress, so that they appear uniformly black when removed from the water (Ref. 118638).

زيست شناسي     واژه نامه (بعنوان مثال epibenthic)

Found in very shallow waters around Lake Malawi that are densely vegetated, but also in lagoons (Ref. 5595). It can occur at temperatures ranging from 23.0-42.0 °C (Ref. 670). It feeds on detritus and phytoplankton (Ref. 5595). A maternal mouthbrooder (Ref. 118638). A large species heavily exploited in Lake Nyasa [= Lake Malawi] and its catchment; males in particular are fast-growing and the species is cultured commercially in Malawi in cages and ponds (Ref. 118638).

Life cycle and mating behavior بلوغ | تولید مثل | تخم ریزی | تخم ها | Fecundity | توزاد ( لارو)

A maternal mouthbrooder (Ref. 118638). Builds basin-shaped nests in shallow water from 0.15 m to 1.5 m deep, in sand overlaid with mud, in the vicinity of rooted aquatic vegetation; females brood eggs and young in the mouth until the young reach a length of about 10 mm (Ref. 670).
