Length-Weight Relationships and Condition Factor of Garra turcica Karaman, 1971 from Asi River Basin, Turkey

Abstract

This study was carried out in Garra turcica Karaman, 1971, obtained from Asi River Basin (Arsuz/Hatay) between September 2017 and March 2018. A total of 124 specimens, 64 females and 60 males, were caught by using electrofisher and tulle net. The dominant length class in the male and female individuals was 8.0 cm, TL. The length-weight relationship was described as W =0.0258L2.761 (R² = 0.973) with negative allometric growth for both sexes. The exponent b of the length-weight relationships (LWRs) values were 2.805 for females and 2.706 for males. The b values for females, males, and both sexes were significantly different from 3.0 (P<0.05). The condition factor (CF) was calculated, 1.601 for both sexes. The study presented a comprehensive description and first reference on length-weight relationships and condition factors for G. turcica according to their sexes from Asi River (southeastern Anatolia, Turkey). The present results will be useful in managing and conserving this species in the River basin.
