TI  - Length-Weight (L-W), Length-Length (L-L) Relationships and Condition Factor (K) of Gobio  artvinicus (Teleostei:Gobionidae) from the Lower Çoruh River Basin, (NE Türkiye)
AB  -     In this study, some basic biological parameters (sex ratio, condition factor (K), LWRs and LLRs) of Gobio artvinicus (Artvin gudgeon) inhabiting Borçka Reservoir and its tributaries from the lower Çoruh River Basin were investigated for the first time. Fish specimens were collected from June 2017 to May 2018 and totally 120 Artvin gudgeon ranging from 8.1 cm to 13.2 cm in TL were sampled. The sex ratio (F:M) was calculated as 1.18:1.00 in favor of females but it did not deviate from the expected ratio of 1:1 (P˃0.05). The total length-weight relationships were determined as W=0.008TL3.159 for females, as W= 0.012TL2.971 for males and as W= 0.009TL3.088 for combined sex. While the b-values which reflect the body shape were significantly different from the isometric growth indicating positive allometric growth (b˃3) for females and combined sex (Pauly’s t- test, P˂0.05), however the b value of males did not differ from the isometric growth (b=3) pattern (Pauly’s t- test, P>0.05). The slopes (b values) were found statistically significant for both sexes (ANCOVA, P<0.05). Results of the LLRs indicated that the values of the correlation coefficient were highly correlated (r2 > 0.9) for each sex and relationship. Mean K values were calculated as 1.128±0.011 for females and 1.102±0.008 for males indicating a good growth condition in this habitat. The present study will provide a baseline on some biological parameters of G. artvinicus to provide a guideline for the fisheries management authority and fisheries scientists for further investigations as well as presents the first known reference on the LWRs and LLRs of this species for the FishBase database. Furthermore, the reported results will contribute to the conservation and sustainability of this species in the area.
