Abstract

The present study investigates for the first time some basic biological aspects such as sex ratio, size composition, length-length relationships (LLRs) and length-weight relationships (LWRs) of Alburnoides fasciatus inhabiting Borçka Dam Lake and its tributaries from the lower Çoruh River Basin located in the northeastern Türkiye. Fish samples were collected from February 2017 to June 2019. Totally 171 specimens ranging from 7.4 cm to 16.2 cm TL and 4.06 g to 46.56 g were sampled. The sex ratio (F:M) was calculated as 1.19:1.00 (χ2 test; P>0.05). The total length-weight relationships were determined as W= 0.008TL3.154 (r2=0.987, N=93) for females, as W= 0.007TL3.183 (r2=0.990, N=78) for males and as W= 0.007TL3.205 (r2=0.981, N=171) for combined sex. The b-values were significantly different from isometric growth (b=3) indicating positive allometric growth of Transcaucasian spirlin for all sexes (Pauly’s t-test; P˂0.05). The regression analysis of LWRs revealed that the coefficient of determination was r2>0.9 showing a highly significant correlation between total length and weight. Results of the LLRs indicated that the values of correlation coefficient were highly correlated (r2>0.9) for each sex and relationship. The differences in b values of the LWR were statistically significant for both sexes (ANCOVA; P

Özet

Bu çalışma, kuzeydoğu Türkiye'de yer alan aşağı Çoruh Nehri Havzası'ndaki Borçka Baraj Gölü ve kollarında yaşayan Alburnoides fasciatus'un cinsiyet oranı, boy kompozisyonu, boy-boy ilişkileri (LLRler) ve boy-ağırlık ilişkileri (LWRler) gibi bazı temel biyolojik yönlerini ilk kez araştırmaktadır. Balık örnekleri Şubat 2017 - Haziran 2019 tarihleri arasında toplanmıştır. 7,4 cm ile 16,2 cm TL ve 4,06 g ile 46,56 g arasında değişen toplam 171 örnek alınmıştır. Cinsiyet oranı (D:E) 1,19:1,00 olarak hesaplanmıştır (χ2 test; P>0.05). Toplam boy-ağırlık ilişkileri dişilerde W=0,008TL3,154 (r2=0,987, N=93), erkeklerde W=0,007TL3,183 (r2=0,990, N=78) ve tüm bireyler için W=0,007TL3,205 (r2=0,981, N=171) olarak belirlenmiştir. b-değerleri, izometrik büyümeden (b=3) önemli ölçüde farklıydı ve tüm cinsiyetler için Kafkas Noktalı İnci balığı pozitif allometrik büyüme göstermiştir (Pauly’s t-testi; P˂0.05). LWR'lerin regresyon analizi, r2>0,9 olduğunu ortaya koymuş ve toplam boy ve ağırlık arasında oldukça önemli bir korelasyon olduğunu göstermiştir. LLR'lerin sonuçları, her bir cinsiyet ve ilişki için korelasyon katsayısı değerlerinin yüksek düzeyde ilişkili olduğunu (r2>0,9) göstermiştir. LWR'nin b değerlerindeki farklılıklar her iki cinsiyet için de istatistiksel olarak anlamlı bulunmuştur (ANCOVA; P
