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)

Öz:
    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.

Aşağı Çoruh Nehri Havzası'ndan (KD Türkiye) Gobio artvinicus (Teleostei : Gobionidae)'un Boy Ağırlık (L-W), Boy-Boy (L-L) İlişkileri ve Kondisyon Faktörü (K)

Öz:
    Bu çalışmada Aşağı Çoruh Nehri Havzası'nda yer alan Borçka Baraj Gölü ve kollarında yaşayan Gobio artvinicus (Artvin Derekayası)'un bazı temel biyolojik parametreleri (cinsiyet oranı, kondisyonfaktörü (K), LWR'ler ve LLR'ler) ilk kez incelenmiştir. Haziran 2017'den Mayıs 2018'e kadar balık örnekleri toplanmış ve toplam boyları 8,1 cm ile 13,2 cm arasında değişen toplam 120 Artvin Derekayası örneklenmiştir. Cinsiyet oranı (D:E) dişiler lehine 1,18:1.00 olarak hesaplanmış, ancak beklenen 1:1 oranından sapma göstermemiştir (P˃0,05). Toplam boy-ağırlık ilişkileri dişilerde W=0,008TL3,159, erkeklerde W= 0.012TL 2.971 ve tüm bireyler için W= 0,009TL3.088 olarak belirlenmiştir. Vücut şeklini yansıtan b değerleri, dişiler ve tüm bireyler için pozitif allometrik (b˃3) olarak izometrik büyümeden önemli ölçüde farklı bulunurken (Pauly's t-test; P˂0,05), erkek bireylerin b değeri izometrik büyümeden (b=3) farklılık göstermemiştir (Pauly's t-test; P>0,05). Eğimler (b değerleri) her iki cinsiyet için de istatistiksel olarak farklı bulunmuştur (ANCOVA, P<0,05). LLR'lerin sonuçları, her bir cinsiyet ve ilişki için korelasyon katsayısı değerlerinin yüksek düzeyde ilişkili olduğunu (r2>0.9) göstermiştir. Ortalama K değerleri, dişilerde 1,128±0,011 ve erkeklerde 1,102±0,008 olarak hesaplanmış ve tür için bu habitatta iyi bir büyüme durumuna işaret etmektedir. Bu çalışma, G.artvinicus'un bazı biyolojik parametreleri hakkında, balıkçılık yönetim otoritesi ve balıkçılık bilim adamlarına daha ileri araştırmalar için bir kılavuz sağlamak üzere bir temel oluşturacak ve FishBase veritabanı için bu türün LWR'leri ve LLR'leri hakkında bilinen ilk referansı sunacaktır. Ayrıca, rapor edilen sonuçlar bu türün bölgede korunmasına ve sürdürülebilirliğine katkıda bulunacaktır.
