Fatty acid composition and Ω3/Ω6 ratios of the muscle lipids of six fish species in Sugla Lake, Turkey

Abstract

Fatty acid composition of the muscle lipids of Carassius gibelio, Pseudophoxinus anatolicus, Sander lucioperca, Tinca tinca, Vimba vimba tenella and Capoeta capoeta in Sugla Lake were determined. In all species, palmitic acid (13.25- 18.54% of total fatty acids) and oleic acid (11.93-34.23% of total fatty acids) were identified as major saturated fatty acid (SFA) and monounsaturated fatty acid (MUFA), respectively. Docosahexaenoic acid (DHA) was found to be the major polyunsaturated fatty acid (PUFA) in T. tinca, C. capoeta, C. gibelio, P. anatolicus and S. lucioperca while the predominant PUFA of V. vimba tenella was eicosapentaenoic acid (EPA). S. lucioperca contained more ω3 fatty acids than the other fish species. The percentages of total ω3 fatty acids were higher than those of total ω6 fatty acids in all species. Since P. anatolicus is endemic and endangered, this species should be protected and produced for future marketing

Determination of fatty acid profiles of total, neutral, and polar lipids in different tissues of Vimba vimba (L., 1758) from Eğirdir Lake (Isparta, Turkey)

“…Many studies from the fish living in freshwater systems revealed that C16:0 and C18:0 were the main components of the saturated fatty acids (SFAs) (Uysal et al, 2006;Guler et al, 2007;Cakmak et al, 2012;Görgün and Akpınar, 2012). The present study also found C16:0 and C18:0 to be the primary fatty acids of SFAs in the V. vimba tissues.…”

“…Kalyoncu et al (2009) reported similar results in the muscle of V. vimba, in which MUFA levels were found to be higher than PUFAs and SFAs in all seasons investigated. At the same time, Cakmak et al (2012) emphasized that V. vimba was a fish species rich in MUFAs when compared to fish species such as Sander lucioperca, Capoeta capoeta, and Pseudophoxinus anatolicus. The data obtained in the present study on the MUFA levels in different tissues of V. vimba seem Table 1.…”

“…These forms of fatty acids are produced by some algae living in aquatic environments as a result of photosynthesis (Moffat and McGill, 1993). However, fish is the main source for humans to obtain long-chain PUFAs (Cakmak et al, 2012). In clinical studies, the health-improving effects of EPA and DHA in fish tissues have been proven in human subjects in terms of cardiovascular parameters and inflammatory processes (Harris et al, 2007).…”

Nutritional and Fatty Acids Profile Analyses of Commonly Consumed Fresh Water Fish Species in Pakistan

“…Their PUFA quantity is amazingly high which ranges from 6.9 to 18.3% (Dey et al, 2015). Another study by Nath et al (2014) has also confirmed these findings, But Cakmak et al (2012) Identified 38 fatty acids from the wild fresh water fish species from Sugla Lake, Turkey. These Turkish fresh water fish species has less quantity of SFAs (21.43 to 21.36 to 26.33%) as compared to Pakistan fish species 48.5-65.7%).…”

“…The amount of lipids and fatty acid composition in fish is known to be influenced by various factors in different species or within a species, such as geographical region, season, feeding habits and diet, age, sex, spawning period etc. Total lipid and fatty acid composition data are important for nutritionists and food scientists; to help them in dietary formulations, nutrient labeling, processing and (Moreira et al, 2001;Haliloğlu et al, 2004;Özyurt et al, 2007;Özoğul et al, 2007;Thammapat et al, 2010;Özden, 2010;Köse et al, 2010;Tufan et al, 2011;Jahkar et al, 2012;Çakmak et al, 2012). Lake Van is the fourth largest terminal and the largest soda lake on earth with the surface area 3574km 2 , total volume 607km 3 and maximum depth 450m, and it is the largest lake of Turkey.…”
