The aim of this study was to define the molecular variability of three populations of the species Chrysichthys nigrodigitatus. The mitochondrial D-loop gene from 27 specimens was sequenced. Geneious software was then used to analyse and compare the nucleotide sequences obtained. The results showed that there was no difference between the nucleotide sequences of fish from the Bia river and the Aby lagoon. These two populations are therefore similar for the gene examined. However, the nucleic acid molecule of the Ebrié lagoon population differs from that of the other two populations by at least three mutations. On the phenogram, two genetically different sets were identified: specimens from the Bia river and Aby lagoon on the one hand, and individuals from the Ebrié lagoon on the other. The three populations of the Chrysichthys nigrodigitatus species are therefore divided into two ecological siblings depending on the environment in which they live.

Abstract: (french)
L’objet de cette étude était de définir la variabilité moléculaire de trois populations de l’espèce Chrysichthys nigrodigitatus. Le gène mitochondrial D-loop, de 27 spécimens, a été soumis à un séquençage. Par la suite, le logiciel Geneious a été utilisé pour l’analyse et la comparaison des séquences nucléotidiques obtenues. Les résultats ont montré qu’il n’existait aucune différence entre les suites de nucléotides des poissons en provenance de la rivière Bia et de la lagune Aby. Ces deux populations sont donc similaires pour le gène examiné. Par contre, la molécule d’acide nucléique de la population de la lagune Ebrié se distingue de celle des deux autres populations par au moins trois mutations. Sur le phénogramme, deux ensembles génétiquement différents ont été identifiés: d’une part, les spécimens de la rivière Bia et de la lagune Aby et d’autre part, les individus de la lagune Ebrié. Les trois populations de l’espèce Chrysichthys nigrodigitatus sont donc divisées en deux fratries écologiques selon le milieu de vie.
