Randall General public http://www.fishbase.org/summary/SpeciesSummary.php?id=2405 Mainly diurnal. There is considerable flexibility in its diet, A. baremoze shifts from zooplankton to zoobenthos, detritus and macrophytes as plankton densities decline (Ref. 28714). Adults are found at a temperature range of 14.6-35.0°C. In the Malamfatori area (Tchad), seine-net fishery on the River Yobe depends on seasonal upstream (from Lake Chad) and downstream migration during the flood (August-December) and dry (January-March) seasons, respectively. Also, there is an intensive gillnet fishery from July-October at the river mouth. A. baremoze moves offshore (in Lake Chad) beginning March. Teugels, G.G., C. Lévêque, D. Paugy and K.

Also present in Nile, Omo, Lake Albert and Lake Turkana (Ref. 2880, 28714). Three populations - previously as subspecies - may be distinguished by slight morphological differences but they have the same ecological charasterics: in Nile River, Lake Albert, Omo River and Lake Turkana ('baremoze'); in Senegal River, Gambia River, Tominé River, Volta basin, Niger basin and Chad basin ('soudaniensis'); in coastal basins of Côte d'Ivoire, namely Sassandra River, Bandama River and Comoé River ('eburneensis') (Ref. 42019).

Feeding adaptation other than zooplanktivory, due to absence of food in non-flooded zones. Flooded zones provide cover and offer various food source. Young fish stay in dense shoals in small inlets along with Micralestes acutidens from October until early April (Ref. 3648).
