    Predator-prey relationships, population dynamics and fisheries productivities of large African lakes. 1988
    Also available in:
    No results found.

    This volume contains 11 papers prepared on the theme of predator-prey relationships, population dynamics and fisheries productivities of African Lakes. The lakes include Malawi, Tanganyika, Victoria, Kivu, Kioga and Abaya as well as Kariba Reservoir. The papers were prepared for the FAO Committee for Inland Fisheries of Africa Working Group on Stock Assessment, Third Session held in Lusaka, Zambia in September 1985. Studies on the biological productivity of Lake Tanganyika are reviewed wit h emphasis on the assessment of the lake's trophic status and its sustained fish production potential. Results have suggested that the lake has a high carbon transfer efficiency at a low rate of primary production, thus it is capable of sustaining high fish yields. However, if sound decisions are to be made on the management of Lake Tanganyika's fisheries, further research will be required on the long term fluctuations in predator and prey abundance and on fish migration patterns.
