Lipid composition of Heterotis niloticus, Brycenus nurse, Gnathonemus cyprinoides and Sarotherodon galilaeus, which vary in scale thickness, were studied. Heterotis niloticus (very thick scales) had the lowest lipid content (13%), while G. cyprinoids (light scales) had the highest lipid content (26%). The common neutral lipids were cholestrol, free fatty acids and cholesterol esters, while diphosphatidyl glycerol, phosphatidyl glycerol and phosphatidyl ethanolamine were the most predominant phospholipids
