In Lake Kariba 360,000 Lake Tanganyika sardines were introduced by the Zambian government in 1967 and 1968 to be fished, here they enter the fishery at about in length when they are 3–4 months old. The bulk of those caught in the fishery are long and about 5 months old. There appears to be a correlation between biomass and fishing effort, as the biomass was 10% lower in 1985 than it was in 1974 when fishing began. The annual catch on Lake Kariba is now between .
