Abstract
The striped sea bream (Lithognathus mormyrus) is a coastal marine teleost of commercial importance from the family Sparidae, for which information on stock boundaries is currently lacking. We developed two multiplex PCR for the collective screening of nine polymorphic microsatellite markers for this species. Five primer pairs are specific to L. mormyrus, the remaining four are identical to previously isolated sequences in Sparus aurata and Pagellus bogaraveo. The number of alleles among 40 individuals from the Western Mediterranean ranged from 8 to 20 and observed heterozygosity values ranged between 0.65 and 0.92. FST estimate obtained between two separate geographic locations indicate that the loci should prove very useful to study genetic population structure in L. mormyrus.
