| Abstract: | The genetic characterization of natural populations of common pandora (Pagellus erythrinus, Sparidae) was studied using allozyme markers. Fish samples (n = 360) were collected from five locations along the Tunisian coasts and one from the Libyan coast. From eight enzymatic systems, 12 putative enzyme-coding loci were resolved, 8 of which were polymorphic at a level of 99%. F statistics indices revealed a significant departure from panmixia with heterozygote deficiencies and a slight genetic differentiation between samples. Neighbor-joining dendrogram constructed by Reynolds genetic distance showed that the populations sampled from the southeastern Mediterranean Sea were more differentiated from the others. |
