A COMPARATIVE STUDY OF MORPHOMETRIC VARIATION IN PARACOBITIS LONGICAUDA (KESSLER, 1872) FROM THE KARATAG AND TUPALANG RIVERS
This study investigates the morphological variation of the eastern crested loach Paracobitis longicauda (Kessler, 1872), an endemic species of the Aral Sea basin and a dominant taxon in the freshwater bodies of southern Uzbekistan. Morphometric measurements of fish specimens collected from the Karatag and Tupalang rivers were analyzed using Student’s t-test. The results revealed no significant differences in 28 out of 36 measured traits, while the remaining 8 traits showed statistically significant differences at the 1% level.
