Abstract: | Wild common carp from two lakes and two rivers in Greece were genetically characterized with sequencing analysis of two mitochondrial
DNA segments: cytochrome b (1119 bp) and D-loop (646 bp). A total of 9 variable singleton sites and 7 unique haplotypes were detected. A common haplotype was found in three
out of the four populations examined, which seems to be the ancestral one and represents the European origin of common carp
from Greece. This haplotype could be also justified by the introductions reported with individuals belonging to the Central
European race, into many natural habitats in Greece. Limited genetic variation — in Evros and Aliakmonas populations — could
be due to bottleneck effects and small effective population sizes, whereas the different haplotypes found in Lake Volvi could
represent different common carp stocks. Values of sequence divergence among Greek haplotypes ranged from 0.0006 to 0.0023.
The Neighbour-Joining (NJ) phylogenetic tree constructed based on the combined sequences, reveals that the populations of
common carp from Greece belong to the European group of populations — which is highly divergent from the South East-Asia cluster
— and to the subspecies Cyprinus carpio carpio. |
