A light fishery for "Ndagala" (Strolothrissa tanganicae) has been practised for many years on Lake Tanganyika. Initially this had a low catch rate, but has since been developed by the introduction of an artisanal fishery unit based on the catamaran. A unit consists of a pair of metal canoes joined together. The fish are attracted by three lights mounted on the structure, and are caught with a pyramid-shaped lift net. Selected beaches have been reserved for the artisanal fishery and the numher of units operating has increased from 12 in 1957 to 538 in 1972. The mean annual catch per unit is 11,000 kg, which is not sufficient for the fishery to be economic. However, prediction of a possible mean catch as high as 40 tons year encouraged the Burundi Government to launch a project with help from the Freedom from Hunger Campaign. This was designed to develop the fishery by the creation of artisanal fishing centres, and to make available a large number of fully equipped catamarans which could be paid for by a system of hire-purchase. The success of the project has illustrated that the furnishing of adequate equipment can bring about a transformation of the traditional fishery.
