| The influence of dietary phospholipid (PL) composition on early development was tested in a 25 day feeding trial with first-feeding common carp (<i>Cyprinus carpio</i>) larvae. A phosphatidylcholine (PC) fraction (PL: 94%, PC: 83%, PI: 1%) and a phosphatidylinositol (PI) fraction (PL: 100%, PC: 3%, PI: 64%) were prepared from soybean lecithin and added (2% on diet dry weight) to a casein-dextrin basal diet. Another diet was supplemented with 2% hen egg yolk PL (PL: 97%, PC: 68%, PI: 0%). A PL-deficient diet contained only peanut oil as lipid source and another one was supplemented with inositol. Final larval morphology was examined by an automatic image analysis system. The three PL fractions markedly improved growth in comparison with... |

| Previous results demonstrated the stimulating effect of soybean phosphatidylcholine (PC) on the utilization of dietary neutral lipid in larval and postlarval fish. The present study further investigated the effect of the degree of saturation of dietary PC on the enhancement of dietary fatty acid incorporation in lipids of turbot. Newly-weaned turbot were fed for 20 days on four isolipidic diets containing the same amount of highly unsaturated fatty acids (HUFA), presented either as neutral lipid, i.e. fish oil ethyl esters, or as polar lipid. Diet FO was a phospholipid-free control diet. Diets HPC, SPC and FPC were supplemented with 3% hydrogenated soybean PC, 3% native soybean PC and 3% marine fish roe PC, respectively.The three PC-supplemented diets... |

| A 28-day feeding trial was conducted for comparing the effect of different dietary phospholipid (PL) classes on the growth of post-larval turbot and on the incorporation of dietary neutral lipid fatty acids into their body lipids. Prior to the experiment the turbot were weaned for one week on a PL-free diet. The nine experimental diets were isolipidic and contained an equal amount of highly unsaturated fatty acids in the form of ethyl esters. They differed by their PL content (0.1 or 2%) and by the PL class composition of the added soybean PL fractions. Compared to the PL-free diet, diets enriched with phosphatidylcholine (PC) resulted in a better growth, a higher triglyceride content (% body dry matter) and increased levels of docosahexaenoic acid (%... |

| A beneficial effect of dietary phospholipid (PL) supplementation in purified diets in terms of survival, growth, resistance to stress tests, and occurrence of deformities has been demonstrated in larval and juvenile stages of various species of fish and crustaceans. The exact determination of PL requirements in larvae is complicated due to the difficulty to bio-encapsulate PL in live prey. Furthermore, the great variety in purity and composition of the PL sources, and the experimental conditions (such as diet formulation and extent of co/prefeeding with live food) makes it difficult to compare requirements determined with artificial diets. Larval stages are extremely sensitive to a dietary PL deficiency and require higher levels of dietary PL than... |
