Abstract

Abstract In the scope of this study, fish fauna of Küçük Menderes River and its tributaries, updated with the comparison of the recent ichthyofaunal studies, as well as the length-weight relations (LWR) and condition factors (CF) were estimated for 7 freshwater fish species belonging to six families from the river basin: endemic Oxynoemacheilus eliasi, Cobitis fahireae; invasive, Carassius gibelio, Atherina boyeri, transloce Perca fluviatilis and the native Squalius fellowesii, Cyprinus carpio. The fish samples were collected with various fishnets and DC electro-fishing devices from six stations in 2018 and 2019. The LWR of the fishes was studied based on 379 specimens. The estimated values of parameter b ranged from 2.884 (A. boyeri) to 3.176 (C. fahireae). The coefficient of determination (R2) was changed between 0.792 to 0.980 for all sampling localities. In the study, Fulton’s condition factor ranged between 0.391 (S. fellowesii) to 3.080 (S. fellowesii); the relative condition factor ranged between 0.346 (O. eliasi) to 2.746 (S. fellowesii), respectively. This research is anticipated to contribute valuable insights for the conservation of the species, while also furnishing essential data to inform future fisheries management studies in the region.

安纳托利亚西部一些特有和外来淡水鱼类的长度-重量关系和状态因子的鱼类学修正案

摘要在本研究范围内，通过比较最近的鱼类研究，对库克门德列斯河及其支流的鱼类动物群进行了更新，并估算了该流域六科七种淡水鱼类的长度重量关系（LWR）和状态因子（CF）：这些鱼类包括：特有的 Oxynoemacheilus eliasi、Cobitis fahireae；入侵的 Carassius gibelio、Atherina boyeri、transloce Perca fluviatilis 和本地的 Squalius fellowesii、鲤鱼。鱼类样本是在 2018 年和 2019 年用各种鱼网和直流电钓设备从六个站点采集的。根据 379 个标本研究了鱼类的低纬度。参数 b 的估计值从 2.884（A. boyeri）到 3.176（C. fahireae）不等。所有采样地点的判定系数（R2）在 0.792 至 0.980 之间变化。在本研究中，富尔顿条件因子在 0.391（S. fellowesii）到 3.080（S. fellowesii）之间变化；相对条件因子在 0.346（O. eliasi）到 2.746（S. fellowesii）之间变化。预计这项研究将为物种保护提供有价值的见解，同时也为该地区未来的渔业管理研究提供重要数据。
