Notes
Samples taken from Lake Mutanda in 1975 indicate that the specific composition of the zooplankton has changed from that in 1962. This change is very similar to that which occurred in Lake Bunyonyi sometime between 1931 and 1962. The most important aspect of the change is the disappearance of three species of Daphnia, together with Ceriodaphnia reticulata, Metadiaptomus aethiopicus, and Caridina nilotica. The 1975 samples indicate lower standing crops of zooplankton in all three lakes, and lower ratios of nauplii to copepodids than in 1962. The possibility of these changes being attributable to human activities is discussed.
