Abstract
The effects of seasonal variation on the proximate and fatty acid compositions of wild female common sole ( Solea solea) were determined. The levels of lipid displayed pronounced seasonal fluctuations with the highest values in February and August (0.45–0.83% fresh weight) and the lowest values in April and November (0.20–0.13% fresh weight). Although protein levels were similar, dry matter fluctuations were observed for all seasons. In the present study, the percentages of EPA and DHA were between 3.36–4.26% of total lipid and 18.75–20.23% of total lipid, respectively, according to the seasons. The composition of fatty acids in August showed that saturated fatty acids were highest followed by n−3 and mono unsaturated fatty acids. The maximum level of n−6 was found in February. The results indicated that the n−3/ n−6 ratios were 3.84, 3.41, 1.89, 1.45 in August, April, November and February, respectively. It was concluded that common sole is a healthy item in the human diet during the fishing period in the eastern Mediterranean coast of Turkey when balanced n−3/ n−6 ratios and EPA and DHA levels are considered.
