The fishery follows the flood itself: fish spread across the plain to breed when it floods, and are caught in large numbers as the water drains back into the Zambezi.
Bream, tigerfish and other catches from the Upper Zambezi and Barotse floodplain are sun-dried or smoke-dried on racks along the riverbank, then sold in local markets to be soaked and stewed later. It's a way of turning a seasonal catch into a food that lasts.
