There are scanty studies about biodiesel production from aqueous organisms in comparison with other sources like plants and microorganisms. residual parts of Silurus glanis fish was used as the provenance to biodiesel production, therefore, the percentage of oils extracted from remaining parts of Silurus glanis fish was showed 28% of the total weight contained the most important fatty acids methyl esters that important in creation of biodiesel, which included Tetradecanoic acid, Hexadecanoic acid, Octadecanoic acid, Hexadecenoic acid, Octadecenoic acid, Octadecadienoic acid , and Octadecatrienoic acid, where the percentage of produced fatty acids methyl esters that important for the biodiesel productivity reached to 92.53% of the total fatty acids yields. Moreover, Octadecenoic acid methyl ester appeared the highest rate of production by 53.95%, followed by Hexadecenoic acid methyl ester and Tetradecanoic acid methyl ester by 16.99% and 7%, respectively. Furthermore, the results of the study showed that the product of fatty acids methyl esters revealed cetane number reached to 59.8 where this number was corresponded with the Iraqi specifications and European standards for diesel.
