Abstract

The aim of this study was to integrate existing mitochondrial DNA data relating to the deepseablue and red shrimp Aristeus antennatus (Risso, 1816) with data obtained by AmplifiedFragment Length Polymorphism (AFLP). A total of 145 AFLP polymorphic loci were scored in236 specimens collected from one Atlantic and seven Mediterranean sample sites. AMOVA resultsrevealed that the overall genetic variation among-populations was lower (11.81%) than withinpopulations(88.19%). The genetic variation between the Atlantic and Mediterranean samples wasfound to be not significant (PhiCT = −0.007; N.S.), indicating that the transition area between theAtlantic Ocean and the Mediterranean Sea does not act as a barrier to gene flow. Bayesian analysisalso demonstrated the absence of genetic differentiation between the Atlantic and Mediterraneanpopulations and within the Mediterranean basin. The results are in agreement with those previouslypublished using mitochondrial markers. Some considerations on the life history traits of the speciesare discussed.
