摘要：

Samples of kingfish of different age groups were collected from the Batinah and Dhofar coasts of Oman. Fatty acids (EA) were extracted from the dorsal muscle samples of the kingfish and analyzed on a Hewlett Packard Gas Chromatograph Mass Spectrophotometer (GCMS). Individual, EA was identified by comparing their retention times with reference samples, which were continued by the NIST98 computer mass spectral library. Specimens collected from the Batinah coast contained slightly higher amounts of total fatty acids compared to specimens of the Dhofar area. The results showed that kingfish from the Batinah area had high contents of polyunsaturated fatty acids (PUEA) compared to saturated fatty acids (SAFA). However, there was little or no difference between PUFA and SAFA in samples collected from the Dhofar region. All samples had more eicosapentacnoic acid (20: 5omega3, EPA) than docosahexaenoic acid (22: 6omega3, DHA). The omega3 types FA were 5-8 folds higher in all samples compared to the (06 type FA. Kingfish from the Batinah region showed higher omega3/omega6 FA ratios than samples from the Dhofar region.
