Three highly consumed fish in Saudi market were evaluated for their
proximate composition in the muscle and in the head and their fatty acids.
The fish species were included Spanish mackerel, (Scomberomorus maculates),
Grouper (Epinephelus coioides) and Yellow-spotted trevally (Carangoides
fulvoguttatus) which respectively known as Kanad, Hammour and Hammam
in Saudi market. The moisture, protein, total lipids and ash of the muscle
tissue and head of the three fish species were found to be between 71.20
to 78.23, 16.19 to 20.20, 0.24 to 4.10 and 1.10 to 8.00%, respectively.
The fatty acids composition in the muscle of fish species was evaluated.
16:0 and 18:0 were the main saturated fatty acids (SFA), 18:1 ω-9,
16:1 ω -7 the main monounsaturated fatty acids (MUFA), while 22:6 ω-3 (DHA), 20:5 ω-3 (EPA) were the main polyunsaturated fatty
acids (PUFA). The ω3/ ω6 ratio was between 2.05 to 7.39 and the
EPA/DHA ratio was approximately 0.30.
