In conclusion, the genetic markers grouped
population into three divergent clusters: East, Middle
and west population. Thus, our present genetic data
supported the three different stocks formerly
distinguished on the basis of morphomeristic and
electrophoretic differences. Preliminary results of mtDNA
analyzing indicate a divergence between three groups.
The high degree of genetic differentiation in South-east
and South-west of Caspian sea showed at the present
study, suggest that further differences might be exist in
two region . In this respect, detailed genetic studies are
needed in order to conform or reject the existence of the
supposed different subspecies of common carp in
Caspian Sea.
