| Abstract |
The statistical analyses of nine meristic characters of Atherina boyeri, collected in Mediterranean lagoon waters, show the homogeneity of the French populations and the heterogeneity of those of the Tunisian lagoons. Of the set of characters taken into account, only the numbers of longitudinal line scales (SC), vertebrae (VE) and pectoral fin rays (PE) support a clear divergence between the individuals of the European and Tunisian lagoons. For these three characters, the group of the Lion gulf and Corsica populations is characterized by higher mean values than those observed in the Tunisian lagoons. |
