Fatty acid profile and total fat content in payangka `fish (Ophiocaraaporos) Nike from Tondano lake in north Sulawesi

The study on fatty acid composition of Payangka fish (O aporos) nike has been performed. The payangka fish (O aporos) nike from Tondano Lake was taken from fish farmers as much as 10 kg. Preparation techniques which conducted involve reception, selection aside from fish samples as follow-up material (dirt) and washing. The sample preparation process was taken in considering to equipment sanitation and hygiene. Samples are washed and then drained and dried at 400C for 24 hours. All parts of the fish body used for analysis. Determination of total fat content using (soklet extraction methods) and identification of fatty acid using Gas chromatography–mass spectrometry(GCMS). Based on analysis result, the chromatogram peak data indicate that amount of fatty acids components in fish payangka (O aporos) nike from Tondano lake in Minahasa, North Sulawesi was detected at least 19 components.
