Tuzla Çayı ve Tercan Baraj Gölündeki Capoeta capoeta umbla HECKEL,1843`nın Bazı Biyo-Ekolojik Özellikleri ile Total Yağ ve Yağ asitleri Kompozisyonlarının Karşılaştırılması

Seasonal effect on fatty acid composition in phospholipid classes and triacylglycerols of male Capoeta umbla

“…The fatty acid results of C. umbla male from the Munzur River are compatible with those obtained from C. umbla (Yılmaz et al, 1995, Aras et al, 2009 and other freshwater fish previously taken from different water sources (Uysal et al, 2008;Cengiz et al, 2012;Çakmak et al, 2012;Satar et al, 2012;Fallah et al, 2013;Kayhan et al, 2015;Emre et al, 2015;Emre et al, 2017;Emre et al, 2018;Emre et al, 2020). The major fatty acids identified in the fish were 16:0, 18:1n-9, DHA and EPA in all seasons.…”

“…In our study, the percentage of 18:2n-6 in the total muscle lipid was lower than in previous studies on the same type of fish (Yılmaz et al, 1996;Aras et al, 2009), while the percentage of 18:3n-3 acid was higher. Henderson and Tocher (1987) reported in their study that the 20:3n-6 ratio in many freshwater fish was 1.5%.…”

“…Palmitoleic acid serves important nutritional and biological functions because this component is essential for fat synthesis and storage, as well as signaling pathways between organs, cell differentiation, and proliferation. In our analysis, the percentage of 18:2n-6 in muscle total lipids was lower than in other studies (Yılmaz et al, 1996;Aras et al, 2009) on the same type of fish, while the percentage of 18:3n-3 acid was higher. Fish consume essential fatty acids such as 18:2n-6 and 18:3n-3, which they cannot synthesize, and use these components as precursors in the formation of twenty-carbon PUFAs.…”

“…According to Ackman (1989), this feature is unique to freshwater fish. The ratio of 16:1n-7 found in our study was significantly higher than the rates found in C. umbla from Hazar Lake (Yılmaz et al, 1996), Tuzla Stream, and Tercan Dam Lake (Aras et al, 2009). This finding demonstrated that the fatty acid composition of fish is affected by the water source.…”

Bi̇ngöl, Murat Nehri̇, Solhan Dere’si̇nde Yaşayan [Capoeta Umbla ((Heckel, 1843)] Si̇raz Baliği Populasyonunun Büyüme Özelli̇kleri̇ Üzeri̇ne Bi̇r Araştirma

“…Su ürünleri kaynaklarının kullanımı ve geliştirilmesinde sürekliliğin sağlanması, yeni av alanlarının tespiti ve stoklardan faydalanma, kaynakların ülkenin sosyal ve ekonomik amaçları doğrultusunda değerlendirilmesi, kaynakları oluşturan türlere ait populasyonların ve stokların durumu ile yıllık verimleri ve bunları etkileyen faktörlerin çok iyi bilinmesi gerekir [5]. Ülkemizin farklı tatlı sularında yaşayan C. umbla populasyonlarının biyolojik özelliklerinin belirlenmesi üzerine bazı çalışmalar bulunmaktadır [6,7,8,9,10,11,12,13,14,15,16,17,18,19…”
