More on author: Günther . Environment: milieu / climate zone / depth range / distribution range Ecology Freshwater; benthopelagic. Tropical Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri Africa: endemic to Lake Chala in Kenya (Ref. 52331 ) and Tanzania (Ref. 118630 ). Size / Weight / Age Maturity: L m   ?   range ? - ? cm Max length : 30.0 cm SL male/unsexed; (Ref. 4967 ) Short description Morphology | Morphometrics Dorsal spines (total): 16 - 17; Dorsal soft rays (total): 11-13; Anal spines : 3-4; Anal soft rays : 10 - 16; Vertebrae : 31 - 34. Diagnosis: A large bodied tilapia, with a relatively large and forward-facing snout, body at least 2.8 times as long as deep (Ref. 4967 , 118638 ). The species can be distinguished by following characters: teeth very small, in narrow bands; pharyngeal bone narrow, its width about 26% length of head, with fine teeth, crowded posteriorly, the blade equal to the median length of the toothed area in young, about 1.5 times as long in adults; pectoral fin usually less than 36% of standard length; anal spines III-IV; scales of chest and belly very small, in some individuals showing an abrupt transition from the flank scales for a short distance behind the pectoral-pelvic interspace; in some the dorsal scales may also be small; and caudal peduncle at least 1.3 times longer than deep (Ref. 2 , 4967 ). Males characterised by an intricate melanin pattern on the head, flank scales that are darker towards posterior side, and a background light grey-blue colour; the dorsal region is darker than the ventral, and ripe males with dark pectoral, anal, caudal fins, while the dorsal fin is dark with orange margins; females with less contrasting colours, with flanks uniformly grey or olive, with a lighter ventral region (Ref. 118638 ). Biology     Glossary (e.g. epibenthic) Only found in Lake Chala (Ref. 2 , 4967 , 36900 ); several non-native tilapias are now established in this small lake as a result of stocking, and Oreochromis hunteri is apparently much less common than previously (Ref. 118638 ). Sometimes swimming in shoals (Ref. 36900 , 55060 ). It feeds on algae and debris off the bottom between the rocks near the shore (Ref. 2 , 55060 ). A maternal mouthbrooder (Ref. 118638 ). Fished in Lake Chala (Ref. 118638 ). IUCN conservation status is critically endangered (Ref. 118638 ).

Bayesian length-weight: a=0.01905 (0.00827 - 0.04391), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  2.0   ±0.00 se; based on food items. Resilience (Ref. 120179 ):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.). Fishing Vulnerability (Ref. 59153 ):  Low to moderate vulnerability (27 of 100).
