| The fatty acid composition of the development stages (fingerling, juvenile and adult) of some pond raised fresh water fishes (Heterobranchus bidorsalis, ‘hybrid’ of H. bidorsalis and C. gariepinus, Chrysichtys nigrodigitatus, Heterotis niloticus and Oreochromis niloticus) were determined by gas liquid chromatography (GLC). Fatty acids abundant in the stages of these fishes are palm tic acid (C16:0), Oleic acid (C18:1) and Linolenic acid (C18:3w3) . Highly unsaturated fatty acid (HUFA) such as C20:4w6, C20:2w3 and C22:4w6 acids were present in small quantity. The common features of freshwater fish is evidently displayed namely the enrichment in linolenic (18:2w6) and / or linolenic (18:3w3) fatty acids. However the presence of high proportions of... |

| Preparative and analytical thin layer Chromatography have been used to purify and separate phospholipids from the total lipids of Callinectes latimanus (Decapoda: Portunidae) and Cardisoma armatum Decapoda: Gecarcinidae). Comparison of Rf values of standards with standard Rf values in the solvent system employed indicated the presence of phosphatidy 1 ethanolamine (PE; Rf = 0.61), phosphatidy 1 choline (PC; Rf =03.34), phophatidic acid (PA; Rf = 0.76) and phosphatidy 1 – N-methy 1 ethanolamine (PNME; Rf = 0.85). An unidentified spot with Rf = 0.93 was also detected. Gas liquid chromatography of the total lipid extract from the two Crustaceans indicated that the predominant saturated fatty acid in the two Crustaceans is palmitic acid (C16:0) with oleic... |
