Melicertus kerathurus represents an economically important resource for fisheries and aquaculture. Sevenmicrosatellite loci from 373 specimens of M. kerathurus collected in different parts of the Mediterranean and NEAtlantic were identified. Four of these microsatellites showed a moderate level of polymorphism, with 2 to 14 allelesper locus, whereas three had a monomorphic profile. Observed and expected heterozygosity ranged between 0.28 to0.64and 0.28 to 0.65, respectively. Three microsatellite loci deviated from Hardy-Weinberg equilibrium in some populations,with a deficit of heterozygosity. Mean Fst values showed significant differentiation among sample sites analysed andindicate that these loci are useful for the study of genetic variation in this species. These results may supply functionalinformation on the population genetic structure of Melicertus kerathurus, valuable for future sustainable managementstrategies.
