Synopsis (short abstract) This document contains the papers presented at the Symposium on Biology, Stock Assessment and Exploitation of Small Pelagic Fish Species in the African Great Lakes Region. The symposium, jointly organized by the FINNIDA/FAO/AGFUND project Research for the management of fisheries on Lake Tanganyika (LTR) and the FAO/UNDP project Inland Fisheries Planning, Development and Management in Eastern/Central/Southern Africa (IFIP), was held in Bujumbura, Burundi from 25 to 28 November 1992. The Lakes a nd Reservoirs included in the 20 Symposium papers are Itezhi-Tezhi, Mweru-Luapula, Malawi, Kariba, Kibu, Tanganyika and Victoria. The small pelagic species treated are Limnothrissa miodon, Stolothrissa tanganicae, Rastrineobola argentea, Poecilothrissa moeruensis and Engraulicypris sardella. The topics covered include biology, life history, growth and mortality and various aspects of the fisheries.Small body size is a feature of Limnothrissa miodon in the man-made Lakes Kariba and Cahora Bassa. Recent reliable determinations of their growth confirm the earlier very high estimates of their mortality. These high mortality rates are consistent with the small body size of the fish. A similar allometric relationship applies to the production/biomass ratios. Because most fish die after a few months there is no relationship between fishing effort and catch. Regulating effort may therefore contribute little to the management of this stock. The greatest risk to the fishery is a collapse of recr uitment and there is an urgent need to understand the factors that regulate reproduction.

    The IFIP project started in January 1989 with the main objective of promoting a more effective and rational exploitation of the fisheries resources of major water bodies of Eastern, Central and Southern Africa. The project is executed by the Food and Agriculture Organisation of the United Nations (FAO), and funded by the United Nations Development Programme (UNDP) for a duration of four years.There are eleven countries and three tergovernmental organisations participating in the project: Bur undi, Ethiopia, Kenya, Malawi, Mozambique, Uganda, Rwanda, Tanzania, Zambia, Zaire, Zimbabwe, The Communaute' Economique des Pays des Grands Lacs (CEPGL), The Preferential Trade Area for Eastern and Southern African States (PTA) and the Southern African Development Coordination Conference (SADCC). The immediate objectives of the project are: (i) to strengthen regional collaboration for the rational development and management of inland fisheries, particularly with respect to shared water bodies; (ii) to provide advisory services and assist Governments in sectoral and project planning; (iii) to strengthen technical capabilities through training; and (iv) to establish a regional information base.
