Neutral and polar lipids comprised almost equal proportions in both liver and muscle. Choline glycerophospholipids (CGP) were the major polar lipids, followed by ethanolamine glycerophospholipids (EGP) in the liver, heart and muscle. Cerebrosides accounted for 28.8% of the brain lipids. All lipid classes of the liver contained high levels (31-17%) of polyunsaturated fatty acids (PUFA), with the exception of phosphatidylserine. The total proportion of n- 6 PUFA exceeded that of n-3 PUFA in all lipid classes of the liver, due mainly to the high levels of 20:4n-6. The highest level of 20:4n-6 occurred in phosphatidylinositol, where it comprised 32.4% of the total fatty acids. The CGP and EGP of the brain contained lower levels of PUFA than those of the liver, muscle and heart. Alkenyl others accounted for 35.8% of the total long-chain moieties in brain EGP. The fatty acid composition of blubber triacylglycerols differed from those of the lipid classes from other tissues in that it had a very low ratio of n-6 to n-3 PUFA (0.3) as a result of a lower content of 20:4n-6. |

The plant by-products were soybean meal, carob seed germ meal and corn gluten meal. Linseed oil was used in order to increase the fat content of the diets and to supply the indispensable fatty acids. Diets containing soybean meal and corn gluten meal gave the best results, comparable to those obtained with the commercial food. Results obtained from the diets containing carob seed germ meal were inferior, especially during the first 50 days of rearing. Haematological characteristics of all fish tested were within the normal values reported in the literature. Liver composition did not indicate any lipid or glycogen accumulation. The results of growth and food conversion are discussed in relation to the cost of production calculated for each diet. © 1985. |
