In the present work we used three molecular techniques (allozymes, RAPDs and mtDNA RFLPs) in order to study the genetic structure of three commercial marine species (Mullus surmuletus, Mullus barbatus, and Pagellus erythrinus). Each species was sampled from three locations within the Gulf of Pagasitikos, Greece and from two neighbouring locations outside the Gulf (Trikeri and Alonissos). Values of genetic heterozygosity and nucleotide diversity for all populations studied were similar or above the mean values observed in marine fishes. None of the three types of molecular markers used revealed diagnostic patterns, which could allow the allocation of individuals to one of the populations. The analyses revealed that the three populations within Pagasitikos were homogenous representing thus a panmictic stock. However, there were evidences of genetic population subdivision between localities from inside and outside of the Pagasitikos Gulf. The results provide essential information for the design of a sustainable management plan of the Gulf of Pagasitikos and its demersal fish resources.
