Alestes baremoze

(Characin, Egyptian Robber, Silversides)

Overview:

Family: African tetras; 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.

Physical Description

[ Back to top ]

Family Alestiidae:

Africa. Following Eschmeyer 1998[1] this family includes all African tetras, formerly a subfamily of Characidae. Maximum length of about 1.4 m attained by Hydrocynus goliath of the Congo.

The family Alestiidae belongs to the Class Actinopterygii (ray-finned fishes) and the Order Characiformes. It contains 18 genera and 109 species. It may be found in Freshwater environments and is primarily Primary freshwater. Some members of this family are used in the aquarium trade. Reproductively, most members of this family are nonguarders. The main mode of swimming of adult fish in this family is carangiform. Compared with other fish, the activity level of this family tends to be normal. This family may be found from 31° n to 26° s and 18° w to 46° e. Etymology of this family name: Greek, alestes, -oy = miller

Species Alestes baremoze:

Feales are commonly 440 cm (Total Length) in length when caught/marketed, but may be as large as 40 cm (Total Length).
