Abstract
Four species of fish reared in southern border of coastal waters in fish farm of Kafer El Shik government (Brullous Lake, Egypt) were studied. Forty of Tilapia, (Oreochromis niloticus); catfish, (Clarias gariepinus); grey mullet, (Mugil cephalus) and thinlip mullet, (Liza ramada) fish were examined for their fatty acid composition under Egyptian breeding
conditions. The isolation, identification and characterization of these fatty acids were carried out by gas chromatography (GC). Most of the fish contained less than 20% lipid by weight.
A large variation was observed between tilpia liver and catfish liver and between catfish muscle and grey mullet and thinlip mullet muscle. Thirty seven individual fatty acids from the muscle and liver from fish were analyzed. Fatty acid composition was analyzed and quantified using gas chromatography after being converted into fatty acid methyl ester
(FAME). The most prominent muscle fatty acids detected were Oleic acid and Myriotoleic acid in tilapia, grey mullet, catfish and thinlip mullet muscles.
Additional amounts of Tricosinoicc acid, Myriotoleic acid, Henoisoanioic acid were observed. Detectable amount of Cis,4, 7, 10, 13, 16, 19 Decsahexaonic acid were present. In additions, the most redominant liver fatty acids detected were Myrisitic acid, Pentdecanic acid and Linolonic acid in tilapia, (Oreochromis niloticus); catfish, (Claries gariepinus); grey mullet, (Mugil cephalus) and thinlip mullet ( Liza ramada),respectively. Additional high presence of Palmetic acid and Myriotoleic acid were found. Detectable amountd of Cis, 13, 16 Decosadonic acid and Cis 11,,14 Eicosoadadieonic acid were observed. The saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), poly-unsaturated fatty acids (PUFA), w-3, w-6, w-7, w-9, EAA, DAA, EAA, EPA, EPA and DHA were illustrated and detailed discussed in muscle and liver of tilapia, (Oreochromis niloticus); catfish, (Claries gariepinus); grey mullet, (Mugil cephalus) and thinlip mullet ( Liza ramada). In addition medicinally important polyunsaturated fatty, acid eicosapentaenoic and docosahe aenoic acids were also identified
