“…However, it was also reported that EPA and DHA levels of sea fish were higher than those of freshwater fish [16]. In the present study, we observed that the levels of total PUFAs, EPA and DHA, were similar to the reported values both in some freshwater fish, Sander lucioperca [3], Cyprinus carpio [17], Clarias gariepinus, Siluris glanis, and Rutilus frisii [10] and in marine fish, Sardinella spp. and Micropogonias furnier [18], Penaeus semisulcatus [19], Epinephelus aeneus, Trigla lucerna, Merlangius merlangus, Siganus rivulatus, Dicentrarchus labrax and Sparus auratus, Boops boops, Mugil cephalus, Sardinella aurita, Pagellus erythrinus, and Solea solea [10].…”

It is well known that fish is beneficial and curative in human nutrition. This arises especially from long-chain n3 polyunsaturated fatty acids (n3 PUFAs), especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are mostly found in fish [1,2]. However, the fatty-acid (FA) composition of all fish species varies according to the season [3], geographical location of the catch [4], diet and feeding [5], size [6], sex, and the state of their reproductive cycle [7]. Water salinity has also an effect on FA composition, particularly on the PUFA levels of fish. The n3/n6 FA ratio is also much lower in freshwater fish than in seawater fish [8,9]. Therefore, it has been argued that the fatty-acid compositions of freshwater and seawater fish differ greatly. Low levels of linoleic and linolenic acids and high levels of long-chain n3 PUFAs generally characterize the FA compositions of marine fish. EPA and DHA are the dominant n3 PUFAs in marine fish. Compared to marine fish, freshwater fish has low levels of n3 EPAs and DHA. High levels of n6 PUFAs, linoleic and arachidonic acids, generally characterize freshwater fish, in particular. Since freshwater fish has lower proportions of long-chain n3 PUFAs than marine fish, the ratio of total n3 to n6 PUFAs is much higher for marine fish than for freshwater fish, varying from 5 to 10 or more [10]. Therefore, the positive health effects of fish with regard to the n3 PUFAs varies with these factors.The Beymelek Lagoon (36q15c39cc-36q16c32ccN, 30q02c26cc-30q04c10ccE) is located on the Western Mediterranean coast of Turkey and is an important fishing area. Economically important fish species migrate to the Beymelek Lagoon for feeding as well as for spawning. These fish are caught at the end of the feeding period before they migrate to the sea, usually at the end of autumn. Many studies have been conducted on the fatty-acid compositions of the Turkish freshwater and marine fish species; nevertheless, no study has so far been carried out on the fatty-acid compositions of the migrant sea fish in the Beymelek Lagoon with brackish water. Thus, the aim of the present study is to determine the fatty-acid compositions and nutritional values with respect to the proportions of n3 PUFAs of five migrant fish species in the Beymelek Lagoon.The fatty-acid compositions of the investigated five fish species are given in Table 1. The levels of major fatty acid groups (total saturated fatty acids, SFAs; monounsaturated fatty acids, MUFAs, and polyunsaturated fatty acids, PUFAs; n3 polyunsaturated fatty acids, n3 PUFAs and n6 polyunsaturated fatty acids, n6 PUFAs) are illustrated in Figs. 1 and 2. In all species, palmitic and stearic acids were the dominant saturated fatty acids, and their proportions varied from 18.94% (in L. aurata) to 22.00% (in C. labrasus) for palmitic acid and from 6.40% (in L. mormyrus) to 12.20% (in C. labrasus) for stearic acid. The variation of palmitic acid levels among the species was not found to be significant (p ! 0.05). It was reported that palmitic ac...

“…The phospholipids contain high levels of the fatty acids eicosapentaenoic and, in particular, docosahexaenoic, but as these are present at relatively constant levels due to their functional importance, variations in fatty acids are mostly found in the triacylglycerols. The fatty acid composition of the muscle lipid of all fish varies according to the season (Blanchard 2005;Uysal and Aksoylar 2005), geographical location of the catch (Ç elik et al 2005), diet and feeding (Cai and Curtis 1990;Gallagher et al 1998), size (Agren et al 1987;Silva et al 1997), sex (Luzzana et al 1996) and the state of their reproductive cycle (Almansa et al 2001;Shirai et al 2001Shirai et al , 2002Uysal et al 2006). Consequently, the positive health effect of fish in relation to the n -3 PUFAs varies according to the season.…”

Fatty acid composition, conjugated linoleic acid and cholesterol contents in the muscles of three freshwater fish species (Barbus plebejus escherichi, Capoeta capoeta capoeta and Rutilus rutilus) were determined under natural extreme temperate (July) and cold (January) conditions. The aim of the study was to determine whether there were differences in these components of the muscle lipids among these three fish species under extreme natural conditions. Samples were analyzed using gas chromatography. Palmitic, oleic, docosahexaenoic and eicosapentaenoic acids were the predominant fatty acids in all fish in both months. The percentages of polyunsaturated fatty acids, n - 3 polyunsaturated fatty acids, n - 6 polyunsaturated fatty acids and eicosapentaenoic + docosahexaenoic acids in the muscle of B. plebejus escherichi and C. capoeta capoeta were significantly higher in January (P < 0.05) than in July. The ratio of n - 6 to n - 3 polyunsaturated fatty acids was lower than 0.60 in all fish species, with C. capoeta capoeta showing the lowest ratio in January (0.36). The levels of cholesterol and conjugated linoleic acid ranged from 103.46 to 150.10 mg/100 g oil and from 16.27 to 35.45 mg/100 g oil, respectively, for all samples in both months. There were no statistical differences in cholesterol levels among the three fish species in July and January. Conjugated linoleic acid contents were significantly higher in January in B. plebejus escherichi and C. capoeta capoeta. Of the three species tested, the extreme temperate and cold conditions affected B. plebejus escherichi the most.

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
