A comparative analysis of the fatty acid profiles in the liver and muscles of male and female Salmo trutta macrostigma

Untitled

“…The n3/n6 ratios observed in this study indicate that hybrid may be healthier to consume than its originated species. This ratio for hybrids were close to values observed by Haliloğlu et al (2004) for cultured rainbow trout at seawater and freshwater and lower than the values of Aras et al (2003b) and Akpinar et al (2009) observed for wild S. trutta macrostigma. Aras et al (2003a) observed much higher n3/n6 ratio for wild Black Sea trout as 6.27.…”

“…Tanakol et al (1999) reported 2.4% EPA and 17.1% DHA for wild freshwater O. mykiss. Akpinar et al (2009) found between 6.45-7.88% EPA and 8.42-7.38% DHA for male and female samples of Salmo trutta macrostigma, respectively. Aras et al (2003b) observed higher levels of EPA as 12.95 % and DHA as 16.07% for the same species indicating the regional effect in the same species in terms of EPA and DHA levels.…”

“…muscle of both sexes for both species as well as their hybrids. Other studies also reported that 16:0 was the most abundant SFA in different trout species that are either wild or cultured (Suzuki et al, 1986;Tanakol et al, 1999;Kiessling et al, 2001;Aras et al, 2003aAras et al, , 2003bErdem, 2006;Akpinar et al, 2009) as well as different marine or freshwater species (Tanakol et al, 1999;Şengör et al, 2003;Luzia et al, 2003;Özyurt et al, 2005;Güler et al, 2007). The variation in individual SFA between sexes were higher for Black Sea trout than brook trout (P<0.05).…”

A comparative study on the fatty acid profiles of total lipid, neutral and polar lipids in the liver and muscle ofCapoeta sieboldii(Steindachner, 1864) andCapoeta baliki(Turan, Kottelat, Ekmekçi, Imamoğlu, 2006) from Tödürge lake (Sivas, Turkey)

“…There were statistical differences in ARA amounts in the liver (1.40%) and muscle (2.73%) of C. baliki (P≤0.05) and the liver (5.06%) and muscle (4.99%) of C. sieboldii had higher level of this fatty acid (P≥0.05). Many studies reported similar results and low amounts of the total n-6 form of PUFA, as determined in our study, in the fi sh from Turkish freshwaters, including S. t. macrostigma (AKPINAR et al, 2009), C. carpio (GULER et al, 2008), V. v. tenella (KALYONCU et al, 2009), and S. lucioperca (UYSAL & AKSOYLAR, 2005. This phenomenon might be the result of the conversion of C18:2 n-6 and C18:3 n-6 to the longer chain fatty acids by the high enzymatic activity of elongases and desaturases in the freshwater fi sh.…”

“…The values obtained for this acid in muscles were 20.50% (C. baliki) and 18.38% (C. sieboldii), while in livers 16.24% for C. sieboldii and 15.83% for C. baliki (P≤0.05). It has been indicated that palmitic acid is an invaluable component of the fi sh tissue lipids (STEFFENS, 1997) and this fi nding is compatible with the data from other studies (GULER et al, 2008;AKPINAR et al, 2009). Other fatty acids exceeding 2% in the tissues investigated were C14:0 (myristic acid), C15:0 (pentadecanoic acid), C18:0 (stearic acid), and C21:0 (heneicosanoic acid).…”
