This model is used to describe the food-web of a rather simple ecosystem: the pelagic area in part of Lake Tanganyka (Burundi). Biomasses and ecological productions are computed. It is shown that most of the ecological production of zooplankton-eater clupeids is consumed by a predator, Luciolates stappersii . Previous estimates of biomasses appear to be relevant and the sensibility of ECOPATH model to variations of the values of needed parameters, mainly P/B is assessed.</style></abstract><accession-num><style face="normal" font="default" size="100%">2230707</style></accession-num><notes><style face="normal" font="default" size="100%">1988French</style></notes><orig-pub><style face="normal" font="default" size="100%">Les relations trophiques dans la zone pelagique du lac Tanganyka (secteur Burundi).
