Diversity and distribution of benthic macroinvertebrates in Kodjoboué lagoon of Bonoua (South-East of Côte d'Ivoire)

This study highlighted the diversity and structure of the benthic macrofauna in the Kodjoboué lagoon. It was conducted monthly from April to September 2024 at four sampling stations. at four sampling stations. Benthic organisms were collected using a dragnet and a Van Veen grab. The inventory revealed 269 insect individuals divided into 17 taxa, 14 families, and 7 orders. The order Heteroptera (29.41%) is the most diverse and abundant (27%). The benthic population is more diverse and abundant at station S4. Predatory organisms predominate in the trophic structure of the insect population in this lagoon. The assessment of water quality using the Hilsenhoff index indicates that, with the exception of the waters at station S4, which are moderately polluted, the waters at the other stations are of poor quality.
