Metric and meristic characters are important to identify fish species and their habitat peculiarities. There are many species that belong to the fish genus Barbus, which is found in tropical and extratropical regions, but there are few studies covering the Coruh basin. Two subspecies of Barbus were found in the Coruh River system of Eastern Anatolia, Turkey: Barbus plebejus escherichi and Barbus capito capito. We collected specimens in seven localities for measurement. The number of vertebra were determined radiographically. Some specimens of B. capito capito have a sharper snout in the segments of Coruh where the water flows faster, suggesting a modification related to current. The biometric measurements vary geographically and could be related to abiotic and biotic factors in the habitat.
测量和可数性状对于识别鱼类物种及其栖息地特征很重要。有许多物种属于鲃属，该属分布于热带和温带地区，但对科鲁河流域的研究很少。在土耳其东安纳托利亚的科鲁河水系中发现了鲃属的两个亚种：埃氏鲃和卡皮托鲃。我们在七个地点采集了标本进行测量。通过X光检查确定了脊椎骨的数量。在科鲁河水流较快的河段，一些卡皮托鲃标本的吻部更尖，这表明其与水流有关的形态变化。生物测量数据在地理上存在差异，可能与栖息地的非生物和生物因素有关。
