Abstract

This study was carried out to determine the growth and reproductive characteristics of Garra rufa Heckel, 1843 infested with Paradiplozoon bingolensis Civanova et al., 2013 in Göynük Stream, Bingol. A total of 267 G. rufa specimens were caught by a casting net between March 2015 and February 2016. The total length of G. rufa ranged from 8.5-19.1 cm and the total weights ranged from 5.8-58.7 g. The most intensive catching was in G. rufa population of 12.0-12.9 cm (30.0%) cm and 15.0-19.9 (25.2%) g in the groups. The mean condition factor was determined as 1.126±0.151 (0.607-1.646). The length-weight relationships were calculated as W= 0.0205 × TL2.758 (r2 = 0.891). The M: F ratio was 1:1.15. The sexual maturity length was recorded as 13 cm total length for males and 14 cm total length for females. Additionally, Paradiplozoon bingolensis was detected on only 218 G. rufa in this population. Of these positive samples, 173 P. bingolensis were isolated from male fish samples, while the females had 228 P. bingolensis. Therefore, female G. rufa specimens from this population were determined to be more predisposed to the infestation (p˂0.01).
