The Tanganyika sardine is known as kapenta or matemba in Zambia, Malawi and Zimbabwe (a related but different fish known as dagaa or ndaga is "Rastrineobola argentea"). Kapenta is two species (Lake Tanganyika sardine, "Limnothrissa miodon" and Lake Tanganyika sprat, "Stolothrissa tanganicae"), both of which are small, planktivorous, pelagic, freshwater clupeid originating from Lake Tanganyika in Zambia. They form the major biomass of pelagic fish in Lake Tanganyika and Lake Malawi, swimming in large schools in the open lake, feeding on copepods and potentially jellyfish. Their major predators are four species of "Lates" which are also endemic to Lake Tanganyika, and are related to (but not the same as) the Nile perch in Lake Victoria. All of these pelagic fish have suffered from overfishing in the last two decades.
