The current study was conducted from October 2013 until the beginning ofSeptember 2014 to estimate the Omega -3fatty acid for three species of marine fish(Acanthopagrusarabicus , Chelonsubviridis and Cynoglossusarels). The study wasconducted during the four seasons winter of 2013, spring of 2014 , summer of 2014and fall of 2014. The oil was extracted by organic solvent extraction, the fatty acidwas estimated using Gas Chromatography connected with mass spectrometry(calculated on the basis of the total amount of the fatty acids), omega–3 percentage ofboth types DHA, EPA has varied between the fish as it reached 56.5% , 55.9% ,67,13% , 49.22% during winter, spring, summer and autumn respectively. Also it wasfound ,by the results, that the percentage of omega -3 type EPA was high in the winteras the percentage was 30.99%, followed by the summer as it was 30.42% and thelowest rate was in the autumn as it was 20.33%, while the percentage of the secondtype of omega -3 DHA was close during the four seasons, as the summer achieved thehighest percentage which was 36.71% and the lowest percentage was in the winter asit reached 25.06%.
