“…The positive correlation between fatty acid profiles in the diets and fillets of many fish species had also been reported in previous studies [15,16,12,10,17,18]. Similar results were obtained by Atalay and Bilal [4] who evaluated different commercial diets in sea bream (Sparus aurata) and sea bass (Dicentrarchus labrax). In addition, Yildiz et al (2008) studying with the sea bream and sea bass, Grigorakis et al [18] and Simões et al [19]studying with meagre reported that the fatty acid composition of fish fillet generally reflects the dietary fatty acids.…”

“…According to FAO data for 2016, the share of aquaculture in total fishing is 46.8. Sea bass (Dicentrarchus labrax) and sea bream (Sparus aurata) are the most preferred fish due to their meat quality, flavoring, and economic value [4]. However, high growth rate [5], good feed conversion, high adaptation capacities and resistance to stress are major aspects that make meagre as a perfect candidate for large-scale fish farming in Europe [6].…”

This study was designed for comparison of biochemical and fatty acid composition of cultured meagre (Argyrosomus regius) in off-shore cage system in two different regions of Turkey. For this purpose, meagre with an average weights of 513.80±52.40 g and 726.52±116.19 g were obtained from commercial fish farms in South (Mediterranean) and North (Black Sea) of Turkey, respectively. No significant differences were detected among the fish originated from the Mediterranean (MSO) and the Blacksea (BSO) in terms of body compositions (p<0.05), except crude lipid and moisture (p>0.05). The fatty acid compositions of MSO and BSO fish showed significantly differences (p>0.05). The fatty acids such as ΣSFA, ΣPUFA, C16:0 (PA), C23:0 (MT), C20:3n-3 (ETA), C22:6n-3 (DHA), Σn-3 and n3/n6 were higher in MSO than BSO. Whereas, the fatty acids such as ΣMUFA, Σn-6, C18:1n-9 (OLA), C20:1n-9 (EA), C22:1n-9 (ESA), C18:2n-6 (LA) and C18:3n-6 (γ-ALA) were higher in BSO fish than MSO fish. However, no difference was detected in the C20:5n-3 (EPA) of fish from both regions. EPA was identified as 3.30±0.05% for MSO and 3.38±0.05% for BSO. No differences were detected in the other fatty acids between two regions (p<0.05). In conclusion, despite the differences in fatty acid compositions of the cultured fish in both regions, high levels of EPA and DHA as well as favorable proportions of n-3 and n-6 fatty acids showed that meagre was valuable food for human nutrition.

“…Since the feeding regime and feed used were the same in both the Fatty acid composition of European seabass study areas, it can be presumed that these differences in biochemical composition are due to the physicochemical properties of the culture environment. The crude protein contents of fish observed in the present study were similar to earlier reports (Alasalvar et al, 2002b;Yıldız et al, 2007;Ozden and Erkan, 2008;Atalay and Bilal, 2014;Baki et al. 2015;Tibaldi et al, 2015), but crude fat contents were found to be higher compared to earlier studies (Alasalvar et al 2002;Dias et al, 2005;Ozogul et al 2007;Ozden and Erkan, 2008;Lenas et al 2011;Chuang et al, 2012;Atalay and Bilal, 2014).…”

The aim of this study was to analyse the fatty acid composition of European seabass Dicentrarchus labrax (Linnaeus, 1758), farmed in marine cages in the Aegean Sea and in the Black Sea coasts of Turkey. The study was conducted between June 2014 and September 2015 using the same feed in all the cage farms. Fish samples representing the stock were collected at regular intervals and morphometric measurements were taken in the laboratory. Fatty acid analyses were carried out by gas chromatography. Biochemical composition of harvested European seabass indicated high dry matter and crude fat values in the Black Sea region and high crude protein and crude ash values in the Aegean region. Significant regional differences between fatty acid composition (p<0.05) was observed, despite being fed with the same diets.

The muscles of lake trout (Salvelinus namaycush Walbaum, 1792), crucian carp (Carassius carassius Linnaeus, 1758), flounder (Platichthys flesus Linnaeus, 1758), gilthead seabream (Sparus aurata Linnaeus, 1758), mackerel (Scomber scombrus Linnaeus, 1758) and tench (Tinca tinca Linnaeus, 1758) were examined. The total mercury (THg) was processed using the Milestone DMA-80 and the fatty acids were analyzed using the 7890A Agilent Technologies chromatograph. The THg content in analyzed fish ranged from 0.024 (lake trout) to 0.092 mg/kg wet weight (gilthead seabream). The muscles of fish examined had lower amounts of SFAs, and n-3 and n-6 PUFAs than MUFAs. The ratio of n-3/n-6 was higher in muscles of mackerel than other fish (p < 0.05). Due to the fact that both the THQ and HI are below 1, the tested fish are safe for the consumer from a nutritional point of view. Similarly, fatty acid indices indicate the safe consumption of selected fish species, and the daily consumption of the recommended dose of EPA + DHA (250 mg/day) and the concentration of mercury in fish calculations showed a hazard quotient for the benefit–risk ratio HQEFA below 1, suggesting that the intake of EPA + DHA poses no evident risk to human health. The ratio was calculated for a person weighing 60 kg. Therefore, it is important to monitor the fish, not only bought in the store, but also caught in various aquatic environments.
