| Abstract | ||
| In the present study, various species of Sparidaefamily in the Persian Gulf and Oman Sea and the population structure of the dominant and significant species of the genus Acanthopagrus were studied based on morphometric and meristic characteristics from June 2014 to May 2016. Fish samples were collected monthly from five different areas in the Persian Gulf and Oman Sea including Khuzestan, Bushehr, the western and the eastern parts of the Strait of Hormuz, and Sistan and Baluchistan. Overall, 54 characteristics of samples comprising 41 morphometric and 13 meristic characteristics were measured and 9 species from Sparidaefamily were identified including Acanthopagrus arabicus, Acanthopagrus bifasciatus, Acanthopagrus berda, Argirops spinifer, Crenidense crenidens, Diplodus sargus kotschyi, Sparidentex hasta, Rhabdosargus sarba and Rhabdosargus haffara. The results of Duncan’s test on data from analysis on classification of morphometric and meristic characteristics, Principal Component Analysis (PCA), Discriminant Function Analysis (DFA), the Cluster test on the morphometric and meristic characteristics and standard length showed significant differences among samples collected from different areas (p<0.05). This result indicated the phenotypic diversity of A. arabicus in the 5 studied areas. The average percentages of the numbers that were located properly in their original population for the morphometric and meristic characteristics were 85.3 and 48.3%, respectively which indicated that the morphometric characteristics had more classification ability than the meristic characteristics. | ||
