Abstract
This study was undertaken with the aim of morphological comparison among deepwater goby, Ponticola bathybius populationsin the southern Caspian Sea. A total of 185 specimens were captured from Bandar-e-Anzali (64 specimens), Salmanshahr (61 specimens) and Miankaleh (60 specimens) using a long beach seine from March to April 2014. 17 landmarks were marked on the left side of body and then 135 interlandmark distances were analyzed using truss-based morphometric method. Also, nine meristic features were counted. Discriminant function analysis (DFA) on morphometric data showed separation among Bandar-e-Anzali, Salmanshahr and Miankaleh population groups (P< 0.05), as in assignment tests using a jack-knifing method, the average proportions of correct assignments were 68%. Non parametric multivariate analysis of Variance MANOVA analysis of the meristic data revealed that there was a statistically significant difference among three population groups (P< 0.001). The Unweighted Pair Group Method with Arithmetic Mean (UPGMA) revealed discreteness between Miankaleh population samples than the two other population samples.
