摘要：

Genetic differentiation and phylogenetic relationships among Diplodus bellottii, D. cervinus, Sparus aurata, Pagrus pagrus, D. sargus and D. vulgaris were investigated by examining the electrophoretic patterns of 22 enzymes, from which 35 loci were detected. The six species were fixed for different alleles at the ADH locus which has been suggested to be the most reliable species-specific marker. Average genetic distances (D) among the six species increased in proportion to the level of taxonomic status (D = 0.54 between congeneric species and D = 1.04 between different genera). Distances among the six species along with the dendrogram obtained, generally agree with the conventional systematics. They fit better with the view including S. aurata and P. pagrus in different genera, in spite of their high morphological similarity. This study reveals useful information for progressive aquaculture.
