Comparative cytogenetic investigation of African catfish Clarias gariepinus (Burchell) and Asian catfish Clarias batrachus (Linn.) was undertaken using C- and NOR-banding techniques. The diploid chromosome number was found to be 56 and 50 respectively in C. gariepinus and C. batrachus. Besides this, there was a variation in chromosomal morphology between two species. NORs were present on one pair of chromosomes and C-bands were localised on seven pairs of chromosomes in both species. However, variations have been observed regarding the position of these bands. The present study indicated presence of variation between two catfishes in chromosome number, morphology and banding pattern. These variations can be used as cytogenetic markers for distinguishing two species and for finding chromosomal composition of the hybrids.
