Abstract
The present study aimed to assess the genetic diversity and genetics makeups of D-loop < /em> in some catfish species. The mitochondrial (mt) D-loop sequences varied in length, from 853 to 893bp. The mt D-loop < /em> region sequences' nucleotide were uploaded to GenBank with accession numbers (PQ589247-PQ589250). The A+T ratio of the mt D-loop < /em> is more concentrated than the C+G. The P-distances among the under studied catfishes, expanded from 0.0188 to 0.0823. The highest value (0.0823) was found between Bagrus bajad and Chrysichthys auratus. However, the lowest P-distance (0.0188) was found between Clarias gariepinus and Bagrus bajad. The results showed that the mt D-loop < /em> appear to be helpful in revealing the phylogenetic relationship of catfishes.
