Abstract

This paper analyzes a 44-year data set of climate and lake water levels and a 29-year record of Kapenta fish stocks in Lake Kariba, Zimbabwe, in order to examine the relationships between environmental factors and determine whether they exert any influence on the Kapenta fish stocks. Changes in lake thermal properties have negatively affected plankton production and nutrient levels. The study brings a wealth of new knowledge to the understanding of the ecosystem from an ecological perspective, which can be used as part of an integrated water resources management framework.
