Abstract

The goal of this study is to investigate the relationships between total length and otolith dimensions and detect the otolith shape index values of Rhodeus amarus sampled from the two different localities (Terme and Terice Streams) in Turkey. A total of 116 specimens of R. amarus were collected. Power models were applied to determine the relationships between otolith dimensions and fish length. Otolith indices were calculated for asteriscus and lapillus pairs. R. amarus were studied ranged in total length from 4.5–8.9 cm for two localities. When the relationships between total length, otolith length and otolith width were examined, the best fit was obtained among total length and otolith length in two localities for both asteriscus and lapillus (r ² > 0.705). Analysis for otolith measurements (asteriscus and lapillus) clearly demonstrated that there was a difference in terms of otolith lengths between samples of Terme and Terice Streams. However, form factor, circularity, roundness values of asteriscus and rectangularity, aspect ratio, ellipticity of lapillus are different between Terme and Terice Streams (p < 0.001).

耳石形状分析和耳石尺寸之间的关系-欧洲苦味杜鹃（Cyprinidae）总长度从土耳其萨姆松省采样

摘要

本研究的目的是调查总长度之间和耳石的尺寸的关系和检测的耳石形状索引值苦竹Rhodeus从两个不同的地方在土耳其（温泉和Terice流）采样。总共收集了116个红mar标本。应用功率模型来确定耳石尺寸与鱼长之间的关系。计算了对星盘菌和天梭菌对的耳石指数。研究了两个地方的R. amarus的总长度在4.5-8.9 cm之间。当检查总长度，耳石长度和耳石宽度之间的关系时，对于星盘菌和天疱疮，在两个位置的总长度和耳石长度之间获得了最佳拟合（r  ² > 0.705）。耳石测量结果（星盘菌和天疱疮）的分析清楚地表明，在Terme和Terice流样品之间，耳石长度存在差异。但是，Termme和Terice流之间的形状因子，圆度，星状圆度值和矩形度，纵横比，椭圆形椭圆度都不同（p <0.001）。
