A kilogramme of Tanganyika sardines (sambaza) that used to cost Rwf4,000 mid this year has shot to Rwf6,000. Sambaza is widely consumed fish species in Rwanda both by low-income earners and upper classes.

Sambaza are thought to have been introduced to Kivu (the 2,700 sq km lake on Rwanda's eastern border with the Democratic Republic of the Congo) in the 1950s from Lake Tanganyika further south, and, despite their reputation as a delicacy, stocks have remained mostly consistent ever since.

Sold dry sambaza go for a higher price than they do fresh. And in Eastern Rwanda, they form a central part of the edible economy; almost every dish in the restaurants along the lush banks of Lake Kivu incorporates sambaza, but perhaps most tastily as the crispy fried accompaniment to a sunset beer.
Borrowed from Swahilisambaza(“to disperse, scatter”), popularized by Sambaza, a credit sharing service developed by Kenyan mobile network operator Safaricom in 2005.
