All of the analyzed fish were collected from the Northwestern regions (Khyber-Pakhtunkhwa) of Pakistan. Proximate analysis was done by using standard AOAC methods, whereas the detailed fatty acid composition was evaluated by using gas liquid chromatography. A significant difference (p&lt; 0.05) was noticed for various proximate parameters and fatty acids profiles among fish species. Palmatic acid (C16:0) was the copious fatty acid of each fish species, with a range from 16.7% to 24.6%. Furthermore, all fish species were found as good sources of polyunsaturated fatty acids (PUFAs) including alpha linolenic acids (ALA C18:3), arachidonic acids (AA C20:4), eicosapentaenoic (EPA C20:5) and docosahexaenoic acids (DHA C22:6) and protein. Whereas, Rainbow trout ranked highest in PUFAs while Mahseer proved to have highest protein contents.</p> Fish composition, Fatty acids profile, Omega-3/n-3fatty acids, Polyunsaturated fatty acids Pakistan Agricultural Scientists Forum https://thejaps.org.pk/AbstractView.aspx?mid=Fish-19-0002
