The SL of 238 barbel specimens studied ranged from 54 to 198 mm, TL ranged from 62 to 226 mm. The sub-populations from all locations appeared to be relatively uniform in all of the characters examined. Six metric characters demonstrated isometric growth, i.e. they were best described by simple linear regressions and one character (eye diameter) was the best described by split linear regression, being isometric with an abrupt change in its growth rate relative to SL. The authors suggest that further morphological investigation of the species is required. Keywords : Morphometry, Ecomorphology, Barbus tauricus, Regression analysis, Sub-populations, Turkey
