Two different fish oils were extracted from yellow striped scad (Selaroides spp) and local catfish (Clarias sp) using wet rendering method and mixture of these oils were analysed using Gas Chromatography for the fatty acids profile and using FTIR for determining the functional group. The research results showed that the omega-3, -6 and -9 contents of mixed yellow stripped scad (Selaroides spp) and local catfish (Clarias sp) oils were 15.03g, 11.65g and 41.20g respectively. While the SFA, MUFA and PUFA contents of mixed fish oils were 32.56g, 41.20g and 26.67g respectively with the ratio of  PUFA/SFA : 0.82. The free hydroxyl (-OH) group of mixed fish oils was observed in wave number  3943.53 cm^-1, while hydroxyl (-OH) binding in carboxylate was observed in wave number 3005.95 cm^-1 and function ester group (-C-O-C-) at wave number 1181.15 cm^-1 in the spectra of FITR analysis. The results showed that mixture oils of yellow striped scad (Selaroides spp) and local catfish (Clarias sp) could be considered as a good natural source of omega-3, -6 and -9.
