| Abstract | Agnebi is the most important river of littoral of Cote d’Ivoire. The first study of benthic macroinvertebrates of this river was studied in the middle stream (Pont Autoroute). This station was visited monthly during 10 months covering the 4 local rainy seasons. Ten (10) samples of the Ekman grab (an area of 0.225 m 2 ) have been analyzed. Benthic macro fauna inventory showed for the whole river, 50 taxa distributed or divided: Oligochetes (2 taxa), Molluscs (14 taxa) and Insects (34 taxa). Five taxa are abundant (superior or equal of 5 % of total number) at Pont Autoroute: Potadoma liberiensis (37,3 %), Gabbiella africana (8,4 %), Cleopatra bulimoides (7,7 %), Mutela dubia (5,9 %) Chironomus spp (5,3 %). Specimen such as Ephemeroptera and Diptera Chironomidae are influenced by temperature and dissolved oxygen. High positive correlation has been established between snails and nitrate. |
