摘要

摘要从30个大鲤鱼和大鲤鱼标本中分别获得了120个星盘。kais的耳石质量与三种鱼类长度（TL、SL和FL）之间存在显著关系。对于OL和三种鱼长的巨大C.macrostomum也获得了类似的关联。对于C.kais，耳石质量（以下简称OM）和鱼叉长度（以下简称FL）之间的关系最高（0.5894）。耳石宽度（以下简称OW）和标准鱼长度（以下称SL）之间的决定系数最低（0.2861）。对于C.macrostomum，OL和FL之间的关系的决定系数最高（0.7280），OM和TL之间的关系最低（0.1717）。分析表明，通过耳石生物特征研究对两种鱼类的体型进行评估是值得信赖的。

Biometric relation between body size and otolith size of Cyprinion kais and C. macrostomum collected from Tigris River, Şirnak Province, Türkiye

Abstract One hundred and twenty asterisci were obtained from 30 specimens each of Cyprinion kais and Cyprinion macrostomum. Significant relationships between otolith mass and the three fish lengths (TL, SL, and FL) were attained for C. kais. Similar associations were obtained for OL and the three fish lengths of C. macrostomum. For C. kais, the highest in the relation between otolith mass, hereafter referred to as OM, and fish fork length, henceforth known as FL (0.5894). The lowest coefficient of determination was observed between otolith width, hereafter called OW, and standard fish length, hereafter referred to as SL (0.2861). For C. macrostomum, the highest coefficient of determination was attained for the relation between OL and FL (0.7280) and the lowest for the relationship between OM and TL (0.1717). The analysis shows that evaluations of the body size of the two fish species investigated through biometric studies of otoliths are trustworthy.
