Survey of the Morphometric variation on Mudskipper (Boleophthalmus dussumieri) in the Coastal Areas of Khuzestan

In order to study of morphological variations on mudskipper populations (Boleophthalmus dussumieri), we collected 31, 26, 23 and 13 fishes from Bahrekan fishing port, Bandar Imam Khomeini, Arvankenar fishing port and Abadan fishing port respectively. Totally, six variations (Four measurable trait belonged to different organs using a digital caliper with 0.01 mm precision, total length with 1 mm precision and total weight using a digital scale with 0.01 gr precision) were measured. Morphometric trait standardized before analyzing to reduce the errors caused by dissimilar growth. PCA and CVA used for surveys of morphometric differentiation among populations. The results showed that there were no significant differences due to close relationship and the relative similarity among populations habitat. PCA result revealed that morphological traits of Bahrekan, Emam Khomaini Port and Arvandkenar fish Port with 70 percent variance variation placed in the same group. Instead, Abadan fish port showed week significant differentiation with 20 percent variance variation with others.
