A karyological analysis of three strains of Clarias gariepinus used in fish culture, originating from different localities in Africa and Asia Minor, and thus representing populations from the distribution limits of this species, revealed an identical karyotype, 2n = 56 with a pair of heteromorphic sex chromosomes (ZW) and a nucleolus organizer (NOR) location in a single pair of chromosomes, for all strains. These results confirm the synonymy between C. gariepinus, C. lazera and C. mossambicus as introduced by Teugels in 1982. (D'après résumé d'auteur)
