| Alestes baremoze (Joannis, 1835) | ||||
| Family: | Alestidae (African tetras) | ( not available ) | ||
| Order: | Characiformes | |||
| Class: | Teleostei | |||
| English name: | Silversides | |||
| Distribution: | Africa: Senegal, Gambia, the coastal basins of the Côte d'Ivoire (Comoé, Bandama and Sassandra), Volta, Niger/Benué and Chad basin (Ref. 2880, 81279). 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). | |||
| Adult biology: | 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). Occurs 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. | |||
| Diagnosis: | Day 5: intestinal tract appears. Days 5-12: less drastic changes, general appearance stays the same. Days 12-23: caudal, dorsal and anal appear. Days 20-30: ventral and adipose appear. Days 15-26: anal rays appear. Days 12-24: tail skeletal structure (urostyle, hypural, and caudal rays) appear. Month 1: fish resemble adult, but have a primordial fin residue along the belly, to anus. See also LARVAE table. | |||
| Climate Zone: | tropical; 15 - 35°C | |||
