Moreover the systematic relationship of M. soiuy and L. abu among other mullet species was investigated in the present study for the first time. Hierarchical cluster analyses of morphometric data were not concordant with the meristic data. Meristic characters in the present study were more discriminative than morphometric characters in terms of taxonomic classification of the mullets. According to meristic data in UPGMA tree, all nine species were grouped in two main branching. In the first branch, C. labrosus and O. labeo were clustered as closest taxa, and being the sister group to the L. aurata. The other four Liza species produced two sub-branching in this group; L. carinata was branched with L. saliens, which is neighbour to L. ramada. In the second branch two species, M. soiuy and L. abu were clustered together and highly isolated from others. M cephalus was clustered as a most differentiated species from all other Mugil species.
