Sagittal otolith morphology and otolith shape of two megrim species, Lepidorhombus boscii and Lepidorhombus whiffiagonis, were compared using descriptive morphological characters and Wavelet shape coefficients. Differences in otolith shape were examined by linear discriminant analysis (LDA). The first discriminant axis explained 66.6% of the variation between the groups, and the second axis 28.5%. Otolith classification based on LDA showed that in 79.5% of cases an otolith can be correctly classified based only on its shape. Relationships between otolith morphometric parameters (length and width) and fish size (total length) were described by fitting simple linear regression models. For L. boscii the highest positive correlation was found between right otolith width and total body length (R2 = 0.82), and for L. whiffiagonis between left otolith length and total body length (R2 = 0.39).

使用耳石形态学和形态计量学对 megrims Lepidorhombus spp 进行物种鉴别。在亚得里亚海中东部

两种megrim物种的矢状耳石形态和耳石形状，鳞翅目和鳞翅目，使用描述性形态特征和小波形状系数进行比较。通过线性判别分析（LDA）检查耳石形状的差异。第一个判别轴解释了组间差异的 66.6%，第二个轴解释了 28.5%。基于 LDA 的耳石分类表明，在 79.5% 的情况下，仅根据其形状就可以正确分类耳石。通过拟合简单的线性回归模型来描述耳石形态参数（长度和宽度）和鱼大小（总长度）之间的关系。为了L. boscii右耳石宽度与全身长度之间的正相关性最高（R2= 0.82)，对于L. whiffiagonis左耳石长度与全身长度之间（R2= 0.39)。
