Length-weight and length-length relationships are very important in fish biology. These parameters can provide information on the stock condition and growth studies. In this study, we report the length-weight and length-length relationships for Luciobarbus pectoralis in the Southeastern Anatolia (Hatay, Turkey). A total of 125 (65 female and 60 male) specimens were captured from Asi River (Orontes River) basin using gill nets in September 2015 and March 2016. The total length and weight of both sexes varied from 15.5-38.0 cm and 35.0-855 g. The values of the exponent b of the length-weight relationships (LWRs) were 3.441 for females and 3.443 for males. The length-length relationship (LLRs) between the three-length measurements (TL-FL-SL) were highly correlated (R2>0.99, P<0.001). This study provides the first comprehensive description of LWRs and LLRs of L. pectoralis from the Asi River (Hatay, Turkey) according to their sexes. Besides new maximum length and weight are reported for L. pectoralis.

Asi Nehri (Türkiye)’nde Bulunan Bıyıklı Balık Luciobarbus pectoralis'in (Heckel, 1843) Boy-Ağırlık ve Boy-Boy İlişkileri

Öz

Balık biyolojisinde boy-ağırlık ve boy-boy ilişkileri oldukça önemlidir. Bu parametreler, stok durumu ve büyüme çalışmaları hakkında bilgi sağlamak içindir. Bu çalışmada, Güneydoğu Anadolu'da (Hatay, Türkiye) bulunan Luciobarbus pectoralis’in uzunluk-ağırlık ve uzunluk-uzunluk ilişkileri tespit edilmiştir. Eylül 2015 ve Mart 2016 tarihlerinde Asi Nehri (Orontes Nehri)'nden solungaç ağları ile toplam 125 (65 dişi ve 60 erkek) örnek yakalanmıştır. Tüm bireyler için örneklerin total boyu ve ağırlığı 15.5-38.0 cm ve 35.0-855 g arasında değişim gösterdi. Verilerin-ağırlık ilişkilerinin (LWR'ler) b üssi katsayısı, dişiler için 3.441 ve erkekler için 3.443 hesaplandı. Üç farklı uzunluk ölçümler (TL-FL-SL) arasındaki uzunluk-uzunluk ilişkisi (LLR'ler) yüksek derecede korelasyon bulunmdu (R2> 0.99, P <0.001). Bu çalışmada Asi Nehri'ndeki (Hatay, Türkiye) L. pectoralis’in LWR'leri ve LLR'lerinin cinsiyetlerine göre ilk kapsamlı tanımlaması yapılmaktadır. Ayrıca bu çalışmada L. pectoralis için yeni bir maksimum uzunluk ve ağırlık bildirilmiştir.
