A systematic sampling of the aquatic macrofauna of the Kalengo River has been achieved of October 2011 to September 2012 in five stations according to the method Man-time. To the whole 56 species were inventoried, repartees in 7 groups taxonomies to know: Bugs (35 species, either 62, 5%), Mollusks (8, either 14,3%), Fishes (6, either 10,7%), Annelids (3, either 5,4%), the Plathelmintheses (2, either 3,6%), Crustaceans and Amphibians (1, either 1,8%). Bugs, Mollusks and Annelids were present in all sites and it during all year round of survey. The evolution of populations of the aquatic macrofauna during the period of survey, watch a certain stability of the total specific wealth and a better representativeness during months of April and June.

Abstract: (french)
Un échantillonnage systématique de la macrofaune aquatique de la rivière Kalengo a été réalisé d'Octobre 2011 à Septembre 2012 dans cinq sites suivant la méthode Homme-Temps. Au total 56 espèces furent inventoriées, reparties dans 7 groupes taxonomiques à savoir: les Insectes (35 espèces, soit 62,5%), les Mollusques (8, soit 14,3%), les Poissons (6, soit 10,7%), les Annélides (3, soit 5,4%), les Plathelminthes (2, soit 3,6%), les Crustacés et les Amphibiens (1, soit 1,8%). Les Insectes, Mollusques et Annélides étaient présents dans tous les sites et cela durant toute l'année d'étude. L'évolution des peuplements de la macrofaune aquatique au cours de la période d'étude, montre une certaine stabilité de la richesse spécifique totale et une meilleure représentativité pendant les mois d'Avril et Juin.
