Analysis of fatty acid profile on Rono Lindu (Oryzias sarasinorum) and Rono Poso (Adrianichthys oophorus) fishes endemic of Central Sulawesi

Abstract Rono Lindu fish (Oryzias sarasinorum), and Rono Poso fish lake (Adrianichthys oophorus) are endemic fish of Central Sulawesi were consumed by the society, but it is have not known nutritional content. This research aims to determine the amount and the differences compositions of fatty acids in rono fish from Lindu and Poso lake. The research of fatty acid composition by using the Gas Chromatography method by changing the extraction of fats/oils into a form of FAME (Fatty Acid Methyl Ester). The results of the research showed that the number of fatty acid levels is different between the two samples. The composition of fatty acids found in Rono fish from Lindu lake is included saturated fatty acids (50.91665%), monounsaturated fatty acids (13.66273%), and polyunsaturated fatty acids (35.42044%). While the composition of fatty acids found in Rono fish from Poso lake is included saturated fatty acids (45.85161%), monounsaturated fatty acids (31.67566%), and polyunsaturated fatty acids (22.50430%).
