Silversides
📖 Overview
Mainly diurnal. There is considerable flexibility in its diet, A. baremoze shifts from zooplankton to zoobenthos, detritus and macrophytes as plankton densities decline . 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.
