Spatial variation in relationships of otolith measurements with body length of Prussian carp, Carassius gibelio (Bloch, 1782) collected from four lentic habitats in Samsun Province, Türkiye

This study aimed to disclose the spatial variability in lagenar otolith (asteriscus) dimensions-total length relationships generated for four Prussian carp, Carassius gibelio (Bloch, 1782) populations (Altınkaya Dam Lake, Bafra Fish Lakes, Lake Ladik and Simenit) Samsun Province, Türkiye. Relationship between weight of fish was also described each population. Samples were obtained from commercial fishermen different periods February 2017 March 2018. The length, height, determined. A non-linear function used define allometric asteriscus measurements body size. slopes regressions acquired right left otoliths at sampling site did not show any significant difference. All found be statistically (P<0.001). r2 values ranged 0.61 0.95, mean percent prediction error varied 3.10 7.45. ANCOVA test determined differences regression three variables. Our findings revealed that development reflected somatic growth, but this by area.
