Résumé: | rare taxa (80%) demonstrates a permanent renewal of zooplanktonic species which are very sensitive indicators of environmental aggression. We note an aging of the hydrosystems and relatively average taxonomic similarities demonstrating intrinsic characteristics specific to each pond, depending on the nature and type of pollutant present. The analysis carried out during this study has allowed us to determine the trophic levels of the ponds' waters, to determine the role of environmental factors and to make a comparative analysis of the zooplanktonic community. This approach is a necessary prerequisite for the restoration and management of the ponds. Decreasing order of pollution of the surveyed ponds allows us to classify them as follows: Kpokolota, Ngaïkada, Côte d'azur, Mopa and Mokolo. |
