Action stations: Natural fish traps in the Okavango
In northern Botswana, the term fish trap is used to describe a section of the Okavango
River (or one of the many channels that flow from it and make up the delta) that becomes
separated from the permanent channel supplying it with water. When this happens, fish
can’t escape and become concentrated in shrinking channels and lagoons. As a result, a
glut of easy pickings attracts large feeding parties of different bird species.
