What it is

This small freshwater species belongs to the family Danionidae. It has a streamlined body suited for open water swimming. Adults reach a maximum total length of thirteen centimetres, though most individuals are smaller. The fish is silvery and built for speed in its native lake environment. It is distinct from marine sardines due to its exclusive habitat in fresh water.

Where it lives

The species is endemic to Lake Malawi and its outlet, the upper Shire River. Its distribution covers waters within Malawi, Mozambique, and Tanzania. It inhabits pelagic zones, meaning it lives in the open water column rather than near the bottom or shore. This restricted range makes it unique to this specific African rift valley system.

How it lives

It is a shoaling fish, forming large groups for protection and feeding efficiency. The diet consists primarily of zooplankton, which it filters from the water. As a pelagic species, it remains in the upper layers of the lake. This behaviour makes it accessible to surface fishing methods used by local communities.

Fish and people

Local households rely on this fishery for income and sustenance. The catch is often dried for preservation and sale in markets across Malawi. Consumers typically eat the whole fish, including the bones, because they become soft during drying. It is commonly served alongside staple dishes such as nsima or ugali in Malawi and Mozambique.
