In 1964 the Lake Kariba Fisheries Research Institute (LKFRI) was created in Kariba, Rhodesia as a United Nations Development Program Project, and executed by the Food and Agriculture Organization (FAD) in cooperation with the Governments of Rhodesia and Zambia. Dr. A. G. COCHE took charge of the Limnological Section and conducted research on the entire lake between January 1965 and January 1966. In 1966 the Central Fisheries Research Institute (CFRI) was created in Chilanga, Zambia by the Department of Wildlife, Fisheries, and National Parks. It was also supported by a UNDP Project executed by FAD. Between 1967 and 1971 Dr. E. K. BALON & Dr. A. G. COCHE were in charge of the Sections of Ichthyobiology and of Limnology respectively. The results of their FAD research activities on Lake Kariba are united in this volume. In the first part A. G. COCHE presents a limnological synthesis. In the second part E. K. BALON studies in detail the fish production and succession. The views expressed are those of the authors and do not necessarily coincide with those of the Food and Agriculture Organization of the United Nations.
