In this study, total lipid and fatty acid profiles of Barbus tauricus samples which were obtained from Melen River Basin during winter, spring, and summer seasons, were evaluated. Total lipid levels were determined 2.27%, 2.37%, and 4.34% in winter, spring, and summer, respectively. The study also determined that the carbon count of 30 fatty acids, composing total fat compositions of B. tauricus caught in Melen Basin, ranges among 12-24. The major fatty acids of B. tauricus are palmitic acid and stearic acid from SFA; palmitoleic acid, trans oleic acid, oleic acid and erucic acid from MUFA and linoleic acid, alfa linolenic acid, eicosapentaenoic acid and docosahexaenoic acid from PUFA. The study is the first one on lipid and fat profiles of B. tauricus, one of the species living in Duzce Melen Basin and having high economic importance, and aimed to investigate total lipid and fatty acid profiles according to the season.

Bu çalışmada Melen Çayı Havzası'ndan kış, ilkbahar ve yaz mevsimlerinde alınan Barbus tauricus örneklerinin toplam lipid ve yağ asidi profilleri değerlendirilmiştir. Toplam lipid düzeyleri kış, ilkbahar ve yaz aylarında sırasıyla %2.27, %2.37 ve %4.34 olarak belirlenmiştir. Çalışmada ayrıca Melen Havzası’ndan avlanan B. tauricus’un toplam yağ kompozisyonunda bulunan 30 yağ asidinin karbon sayılarının 12-24 arasında değiştiği tespit edilmiştir. B. tauricus'un başlıca yağ asitleri, SFA için palmitik asit ve stearik asit; MUFA için palmitoleik asit, trans oleik asit, oleik asit ve erusik asit ve PUFA için linoleik asit, alfa linolenik asit, eikosapentaenoik asit ve dokosaheksaenoik asittir. Bu çalışma, Düzce Melen Havzası'nda yaşayan ve ekonomik önemi yüksek türlerden B. tauricus'un lipid ve yağ profilleri üzerine yapılan ilk çalışma olup, toplam lipid ve yağ asidi profillerini mevsimlere göre araştırmayı amaçlamaktadır.
