| Abstract: | The common dentex, Dentex dentex, is a fish species which
inhabits marine environments in the Mediterranean and Northeast Atlantic
regions. This is an important species from an ecological, economic and
conservation perspective, however critical information on its population
genetic structure is lacking. Most samples were obtained from the
Mediterranean Sea (17 sites) with an emphasis around Corsica (5 sites),
plus one Atlantic Ocean site. This provided an opportunity to examine
genetic structuring at local and broader scales to provide science based
data for the management of fishing stocks in the region. Two
mitochondrial regions were examined (D-loop and COI) along with eight
microsatellite loci. The COI data was combined with publicly available
sequences and demonstrated past misidentification of common dentex. All
markers indicated the absence of population genetic structure from the
Bay of Biscay to the eastern Mediterranean Sea. Bayesian approaches, as
well as the statistical tests performed on the allelic frequencies from
microsatellite loci, indicated low differentiation between samples;
there was only a slight (p = 0.05) indication of isolation by distance.
Common dentex is a marine fish species with a unique panmictic
population in the Mediterranean and likely in the Atlantic Ocean as
well. |
