Abstract

The fatty acid composition of the liver oil from the Black Sea dogfish Squalus acanthias, as well as its seasonal variations were determined. A scheme for concentration of polyunsaturated fatty acids from the dogfish liver oil by urea complexation was proposed. From 360g of free fatty acids a 48g concentrate was obtained, containing 7,8% C_20:4, 16,4% C_20:5. 9,2% C_22:5 and 49,7% C_22:6.
