In this study, it was aimed to reveal the relationships between fish size and otolith length/height/width of Alburnus derjugini and Vimba vimba species sampled from Harşit Stream. A total of 80 specimens of A. derjugini and 71 specimens of V. vimba were collected. The relationships between the total length of fish and the otolith dimensions were determined using power models. Otolith length and otolith height/width were calculated for asteriscus and lapillus pairs in two species. The total length ranges of A. derjugini varied between 7.4-19.2 cm, and the total length of V. vimba ranged between 10.8-17.3 cm. When the relationships between total length and otolith length/height/width for asteriscus and lapillus were evaluated, the best fit was obtained among total length and asteriscus otolith height in A. derjugini (r2>0.883) and V. vimba (r2>0.746). In both species, while otolith measurements did not show statistically significant differences between sexes, right and left otolith measurements differed. For this reason, fish size-otolith measurements were calculated and evaluated separately for the right and left otoliths.
