Gediz Nehri Havzası Lentik Sistemindeki (Türkiye) 15 Farklı Tatlı Su Balığı Türünün Boy-Ağırlık İlişkileri

Öz

Çalışmanın amacı, Gediz Nehri lentik sisteminde yayılış gösteren tatlısu balık türlerinin boy-ağırlık ilişkilerini belirlemektir. Balık örnekleri Kasım 2016 ve Nisan 2017 tarihlerinde Gediz Nehri lentik sistemindeki (6 farklı lokalite), çokgözlü solungaç ve kıyı sürütme ağları ile toplanmıştır. Boy-ağırlık ilişkileri, 8 farklı aileye (Cyprinidae, Leuciscidae, Acheilognothidae, Gobionidae, Atherinidae, Cobitidae, Poeciliidae, Gobiidae) ait, 15 balık türü (Luciobarbus lydianus, Barbus pergamonensis, Cyprinus carpio, Carassius gibelio, Petroleuciscus smyrnaeus, Alburnus battalgilae, Squalius fellowesii, Chondrostoma holmwoodii, Vimba vimba, Rhodeus amarus, Pseudorasbora parva, Atherina boyeri, Cobitis kurui, Gambusia holbrooki and Knipowitschia mermere) için tahmin edilmiştir. Hesaplanan b ve R2 değerleri sırasıyla, 1,9348 ile 4,3466 ve 0,7072 ile 0,9986 arasında değişmektedir. Çalışmada, iki tür için mevcut literatürde bildirilenden daha uzun bir maksimum uzunluk değeri tespit edilmiştir. Ayrıca bu çalışma havzadaki dört endemik tür için boy-ağırlık ilişkisi parametrelerinin ilk kayıtlarını sunmaktadır.

Length-Weight Relationship of 15 Different Freshwater Fish Species in the Gediz River Basin (Turkey) Lentic System

Öz

The aim of study is to determine the length-weight relationship of freshwater fish species in the Gediz River basin lentic system. Fish samples were collected between November 2016 and April 2017 using multi mesh gillnets and beach seine nets from six different locations in the Gediz River basin lentic system. Length–weight relationship was estimated for 15 fish species (Luciobarbus lydianus, Barbus pergamonensis, Cyprinus carpio, Carassius gibelio, Petroleuciscus smyrnaeus, Alburnus battalgilae, Squalius fellowesii, Chondrostoma holmwoodii, Vimba vimba, Rhodeus amarus, Pseudorasbora parva, Atherina boyeri, Cobitis kurui, Gambusia holbrooki and Knipowitschia mermere), belonging to 8 different families (Cyprinidae, Leuciscidae, Acheilognothidae, Gobionidae, Atherinidae, Cobitidae, Poeciliidae, Gobiidae). Computed exponent b and R2 values ranged from 1.9348 to 4.3466 and 0.7072 to 0.9986, respectively. In the study, a longer maximum length value was determined for the two species than reported in the literature. In addition, this study presents the first records of LWR parameters for four endemic species in the basin.
