Global index methods based on aquatic macroinvertebrates are commonly used in bioindication. However, these global index methods cannot be used to diagnose the real causes of degradation. This study therefore aims to integrate recent theoretical advances linking the bioecological strategies of organisms (maximum size, life cycle, food type, feeding mode, respiration and locomotion) to disturbances in their environment. Five (05) reservoirs were visited. Sampling took place from June 2016 to June 2018. A total of 68 taxa were identified, divided into 35 families, 11 orders and 3 classes (Achaetes, Gastropods and Insects). The analysis of the bioecological characteristics of macroinvertebrates in the aquatic environments of the hydrosystems studied in the north of Côte d’Ivoire showed that The Torla, Korokara, Noumousso and Mambiadougou dams would be characteristic of resilience with small organisms, short life cycle and tegumentary respiration, whereas the Sambakaha station would be characteristic of resistance with small organisms, short life cycle and aerial respiration. published by the Journal of Biodiversity and Environmental Sciences | JBES
