This study aims to provide basic data of aquatic macroinvertebrates in Kodjoboué lake (South-East of Côte d’Ivoire) for their potential use for water quality assessment. Four sites (K1-K4) were sampled during eight campaigns from June 2014 to May 2017. At each site macroinvertebrates were collected using a kick-net (25 x 20 cm, 500 µm mesh size). Environmental variables were recorded also. Water was collected from each sampling site for nutrient (phosphorus, nitrate) analysis in laboratory.
In total 74 taxa have been inventoried and subdivided into 4 classes (Malacostraca, Arachnida, Insecta, and Gasteropoda). The most diversified class was Insecta with 91.89% of the Taxa inventoried. Among the insects found, the most diverse order was the order of Coleoptera (19 taxa, 8 families) followed Diptera (15 taxa, 7 families) Heteroptera (13 taxa, 8 families) and Ephemeroptera (7 taxa, 5 families). The taxa identified as constant were Hydrachna sp., Ephemeroptera (Baetis sp., Cloeon sp.), Odonates (Pseudagrion sp.), Heteroptera (Diplonychus sp., Eurymetra sp.), Coleoptera (Pseudobagous Longulus, Hydrovatus sp., Limnius sp.), Chironomidae (Polypedilum deletum, Dixa sp.). Taxa distribution was strongly influenced by environmental variables such as nitrate, phosphorus and temperature. Kodjoboué lake was less disturbed.
