In this context, fish samples obtained from Abdal Stream, Akçay Stream, Engiz Stream, Istavloz Stream, Kaynatma Stream, Mert River, Taşkelik Stream, Terme Stream, Tersakan Stream, Yeşilpınar Stream. The difference between the right and left otoliths were found to be statistically significant in the Istavloz Stream and Tersakan Stream for the asteriscus and in the Abdal Stream for the lapillus (p <0.05). OMA (x) and absolute mass asymmetry (ǀxǀ) for the asteriscus otolith and lapillus otolith were estimated separately by locality. In all localities, the mean mass asymmetry (x±SE) values for Sqaulius sp., for the asteriscus otolith and lapillus otolith were 0.00835±0.00280 and -0.00088±0.00246, and the absolute mass asymmetry (ǀxǀ±SE) values were 0.03669±0.00216 and 0.03324±0.00182, respectively. OMA-fish length and absolute mass asymmetry-fish length relationships for asteriscus and lapillus otoliths were determined using the linear relationship equation. According to the results of this study, there were no statistically significant differences among the localities in terms of asteriscus OMA/absolute mass asymmetry and lapillus OMA/absolute mass asymmetry (Kruskal Wallis Test, p>0.05). This is the first study in which OMA and absolute otolith mass asymmetry of Squalius sp. living in the freshwaters of Samsun province were investigated, and their relationships with fish length were evaluated.}, number={2}, publisher={Balıkesir University}, organization={Ondokuz Mayıs University}
