The seasonal effect in the fatty acid composition of total lipids of four fish species, white needle (Hemiramphus brasiliensis), black needle (Hyporhamphus unifasciatus), mackerel (Scomberomorus cavalla), and sardines (Opisthonema oglinum) was evaluated. Fish samples were collected from coastal regions of the State Pernambuco of Northeastern Brazil in two seasonal periods (summer and winter). The results showed that fatty acid composition of total lipids values was slightly higher in the winter for all species, however, with no significant statistical difference between seasons, except for the pentanoic fatty acid (C15:0) content, which showed a significantly higher value in mackerel, in the summer. The highest contents of docosahexaenoic and eicosapentaenoic acids were observed in sardines, which also presented the best lipid profile. All examined species contained ω-3/ω-6 and ω-6/ω-3 ratios that are nutritionally recommended and could be considered a source of benefits to human health.
