Population substructure of Sepia officinalis sampled along the Tunisian coastline was studied. We have scored the genetic variation of the mitochondrial gene cytochrome oxidase 1. A total of 20 specimens from four sampling sites were analysed and revealed 12 different haplotypes. Haplotype diversity showed a decreasing north to south gradient which may be explained by the hydrogeography of the study area. The overall estimate of genetic divergence (FST) revealed significant genetic differentiation between the pair-wise population comparisons supported by the AMOVA analysis which reveals significant genetic divergence. Finally, populations showed an excess of rare haplotypes. The mismatch distribution and several population genetic statistics indicate that the excess of rare variants is due to a recent expansion for Djerba and Kelibia populations. For Rades and Bizerte populations a constant population size was detected. These findings are important for fisheries management to preserve this marine resource for long-term utilization.
