Description:
Neogobius caspius is a small benthic fish that is native to the Caspian Sea. The importance of this fish is because of it is role as a main food resource of the Sturgeon fish. The genetic diversity of N.caspius populations in the Caspian Sea was studied using microsatellite technique. In the study 95 Samples of Neogobius caspius from two regions (torkman port and Chalus) in south Caspian Sea were collected. DNA was extracted using 12 pairs of microstellite primers polymerase chain Reaction (PCR) was conducted. DNA Bands were analyzed using uvdoct and GenAlEx software package. Out of 12 microsatellite primers, 11 loci were produced, in which 5 of them were polymorphic ,6 monomorph and one of them showed smear. Average of observed and expected hetrozygosity was 0/798 and 0/843 respectively. Significant genetic differences between 2 regions was observed (P 0/01). Deviations from hardy- Weinberg equilibrium were in all cases. These results indicate that at least, 2 population of Neogobius caspius exist in the south Caspian sea.
