| Resumo: |
A karyological analysis of an artificial hybridization (reciprocical crosses) between two African clariid catfish, #Clarias gariepinus$ (Burchell, 1822) and #Heterobranchus longifilis$ Valencienne, 1840, was performed. #C. gariepinus$ has a standard karyotype of 2n = 56, while #H. longifilis$ has 2n = 52. The hybrids revealed an intermediate karyotype (2n = 54), and it appears as if they have totalized the haploid chromosome number of both parental species, excluding gynogenesis or androgenesis. The hybridal karyotype is considered as aneuploid, although the hybrids proved to be fertile. No variation was found in the hybride karyotype. (Résumé d'auteur)
