Abstract

Geographic and temporal genetic variation of allele frequencies at 21 isozyme loci were examined in two populations of common Pandora, Pagellus erythrinus (Linnaeus, 1758, Sparidae). Fishes were sampled from Western and Eastern Mediterranean basins off Tunisian coasts over one year at the beginning of each season. Analysis of genetic diversity showed a low level of heterozygosity for all populations (average H e=0.052). Fixation indices reflected a significant departure from Hardy-Weinberg equilibrium with heterozygote deficiencies, slight spatial differentiation between both sampling localities (F ST=0.003, P=0.017) and temporal genetic stability at seasonal and annual scales. Annual genetic variation was evaluated over a five-year period estimated indirectly from fish otoliths. Comparison of genetic diversity between year classes of both locations showed an increase of the H e values concurrent with age, supporting the hypothesis of the high variance in individual reproductive success. Finally, our results suggest that the effective population size of Pagellus erythrinus is large and genetic drift is weak but variable, especially between successive adult year classes for both sampling locations.
