Assessing of Water Quality of Lake Dogodogo in Burundi Based on Zooplankton Diversity Indices

A study of zooplankton diversity and water quality Lake Dogodogo located in West Burundi was carried out from April to July 2021 six sampling stations, with four selected the littoral zone two remaining pelagic one. The main objective assess using indices for a better management this fishery resource essential surrounding populations. collected twice month between 8 A.M 11 each time. samples were taken vertically plankton net 50 µm mesh size, 26 cm diameter 0.5m depth. We recorded 30 species, 19 rotifers, 9 copepods 2 cladocerans. number species varied one station another zone. abundance higher than then highlighted specific zone, such as Anuraeopsis fissa, Brachionus angularis, calyciflorus, falcatus Keratella tropica. These latter are indicators high trophic level. According calculated, Dogodogo’s is moderately polluted by low level contamination agricultural origin. Therefore, it necessary protect important fish production purposes, which protein supply human life.
