Habitat and Ecology [top]

Habitat and Ecology: This species has been recorded throughout the pelagic zone from the surface to 220 m. In the southwestern arm it was mostly abundant between 75 and 100 m. Males in breeding colouration were caught throughout the year and ripe females are also known to occur throughout the year thus indicating that this species may breed all year round. Females mouthbrood young of large sizes (up to 2.3 cm SL). Its size at maturity for females was 10.5 cm SL. It has an average fecundity of 15 eggs for females of 14-18 cm TL. It feeds on plankton and crustaceans occasionally taking insect larvae, cichlid fry as well as diatoms and other algae. It mainly occurs in the mid-water trawl catches as well as the catches of deep water bottom trawls and pair trawls. It also occurs in catches of chilimira nets. It has been reported that in the offshore waters most individuals caught were either larger than 11 cm or small fry while intermediate sizes occurred in the trawl catches in the south eastern arm of the lake. This species is probably the most important commercial species in the southeast arm of the lake. It probably has the highest biomass of any cichlid in the lake (with an estimated total biomass of 87,000 tons in the pelagic zone).
