Description

The Lake Rukwa sardine is a small cyprinid endemic to Lake Rukwa in Tanzania. The species grows to about 10 cm and has a slender, silvery, sardine-like body. It forms large schools in the open water of the lake and feeds on small zooplankton and insects. Although it could support a substantial fishery, this is barely developed.
