“…The Marahoue region is located in central-western Côte d'Ivoire between longitudes 5°15 and 6°30 West and latitudes 6°00 and 8°00 North (Figure 1). This region has many advantages for the practice of continental fishing because it benefits from an important hydrographic network with the Bandama River [9]. Indeed, the Bandama River watershed is drained by two main tributaries, the White Bandama and Marahoue Rivers, which intersect in the vicinity of the town of Bouaflé.…”

Diversity and Degree of organization of the ichthyological population of two tributaries of the Bandama River in the Marahoue region located in the center-west of Côte d'Ivoire were studied. Indeed, the two tributaries of the Bandama River that are Marahoue and White Bandama Rivers draining this region are subject to numerous disturbances, the main one being gold panning. Data collection was conducted from September 2019 to November 2020 from experimental and artisanal fisheries. The mesh sizes of the gillnets used for the experimental fishery varied from 10 to 40 mm mesh size. The results showed a dominance of the order Siluriformes represented by 6 families and 18 species in the Marahoue River against 4 families and 13 species in the White Bandama River. Also, the Shannon Index (H') values obtained in the White Bandama River (H' fluctuates from 2.26 to 2.33 bits/ind) are lower than those obtained in the River Marahoue (H' fluctuates from 3.02 to 3.14 bits/ind). Our results also highlighted the equitability. This index appeared relatively high in the Marahoue River (E varies from 0.77 to 0.80) compared to the White Bandama River (E varies from 0.5 to 0.57). Consequently, the Marahoue River appears to be more stable and has a good degree of organization of the ichthyological population compared to the White Bandama River.
