Bream (Abramis brama orientalis) is one Caspian Sea bony fish and Aras Dam Lake. This fish is related to the family Cyprinid. During the recent decades because of a decrease in its population in Iranian Caspian sea coast and following to artificial reproduction of a brood stock of Bream in 1986, its genetic diversity has reached to zero in Iranian Caspian sea coast. It has been decided that by entering Bream form Azerbaijan Republic and Aras Dam Lake an increase in its genetic diversity can occur. For this reason in 2002-2003. 30 Bream pieces was catch from 2 habitats and was surveyed of molecular genetic aspects. For that after DNA extraction by Phenol — Chloroform method from a piece of fishʹs fine, a survey had been done on a piece of Mitochondrion genome by the length of 3500 bp contains of tRNA - leu , tRNA - glu , Cytb , ND 5/6 by PCR - RFLP technique. Between 17 used enzymes four of them DraI, BCLI, HaeIII and BanII showed diversity which totally 6 Haploids was recognized. Caspian sea (Azerbijan Republic coast) Bream samples in compare with Aras Dam lake Bream (0.35%) had the most diversity. Mean while Azerbaijan Republic coast samples had all 6 haploids while Aras Dam Lake had just 2 haploid. Also statistical analysis by Monte Carlo test by 1000 repetition showed a significant difference between Azerbaijan Republic coast samples and Aras Dam lake sample (P < 0/0001).
