Allozymic variation of 20 loci was investigated in two samples of Atherina boyeri collected in the Mediterranean Sea from the coast of Trappeto and Marsala Lagoon (Sicily, Italy). Five loci were polymorphic (PGM*, EST-1,2*, SOD-2*, PGI-2*) and appeared to be in Hardy-Weinberg equilibrium. A significant Fst mean value (0.02) (G = 23.77, P < 0.05, df = 5) showed that the samples can be considered as two distinct local populations and supports previous morphometric discrimination.
