Silversides (Alestes baremoze) fish species information

Scientific Name
Alestes baremoze

Common Name
Silversides

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.
