Abstract
This study was conducted to provide length-weight (LWRs), length-length (LLRs) relationships and condition factor of Oxynoemacheilus seyhanensis from seven habitats belonging to three inland water basins of Turkey. A total of 166 specimens were collected from Yıldızeli, Taşköprü, Suşehri (Kızılırmak basin), Büyükpotuklu, Pınarbaşı and Örenşehir (Seyhan basin) and Akdağmadeni (Yeşilırmak basin) rivers during 2017-2019. The mean (±SE) of the total, fork lengths and weight were calculated as 6.49±1.59 cm, 6.35±1.60 cm and 3.47±2.41 g, respectively. b constant of LWRs ranged from 2.29 (Suşehri) to 3.52 (Büyükpotuklu), showing growth pattern of positive allometric in all studied populations except Suşehri (negative allometric), Pınarbaşı (ısometric) and Örenşehir (isometric) population. Condition factor was ranged from 0.92 (Pınarbaşı) to 1.15 (Örenşehir). In all length-weight and length-length relationships with r2 were higher than 0.91. The results of above-mentioned parameters for this deep-bodied stone loach showed that wide range of b-value shows morphological flexibility of this species in different habitats.
