| A standard experimental diet was developed to study lipid nutrition in marine fish larvae during weaning and first ongrowing. Basal diets were prepared by extrusion-cooking, crumbling of the pellets, and sieving to obtain particles in the size ranges 150-300 µm and 300-500 µm. Three protein sources in the extruded basal diet were evaluated: (1) micronized cod protein granulate (COD); (2) a mixture of casein, gelatin, and albumin (CGA); (3) a mixture of cod fish meal, whey protein, soybean protein concentrate, albumin, hemoglobin meal, and wheat gluten (MIX). A variable lipid fraction was added to the extruded nucleus by coating the particles with an emulsion, coconut oil (COCO), or fish oil emulsion (FO), in a fluidized bed granulator.

| In this study baker's yeast was evaluated as a substitute for live <i>Dunaliella tertiolecta</i> algae in the culture of the brine shrimp <i>Artemia</i> . Consumption of fresh baker's yeast resulted in poor growth and survival of brine shrimp. However, the nutritional value of the yeast significantly improved after complete removal of the yeast cell wall by enzymatic treatment. Baker's yeast was also made digestible for <i>Artemia</i> by simple chemical treatment which did not reduce rigidity of the yeast cell. The external mannoprotein layer of the yeast cell wall is probably the major barrier to digestion by <i>Artemia</i> . Chemically treated baker's yeast offers promising possibilities as a substitute for... |

| Decapsulated <i>Artemia</i> cysts were used to study the factors which induce the superior performance of live organisms as food for fish larvae. The biochemical composition, the in vitro protein digestibility, and the total proteolytic and trypsin activities in cysts and nauplii of <i>Artemia</i> were determined at different developmental stages as a function of incubation time. Six different incubation times were studied: 1, 6, 11, 16, 21 and 25h of development, which cover cyst and early nauplii stages. The individual dry weight of <i>Artemia</i> decreased through development. The individual protein and lipid content (µg ind<sup>-1</sup> remained constant during development until the time of hatching after... |

| Although the requirements for highly unsaturated fatty acids (HUFA), primarily eicosapentaenoic acid (EPA, 20:5n-3) and docosahexaenoic acid (DHA, 22:6n-3), have been demonstrated for various species of marine fish, major controversies continue to exist over what constitutes the optimal dietary intake of fatty acids and the efficiency of various lipid classes in supplying essential fatty acids. Furthermore, fatty acid requirements have been determined primarily in larval stages using enriched live food and in juvenile fish using pelletized diets, whereas fatty acid requirements during and just after the critical period of weaning are poorly documented. This paper reports on the development of a standard diet that yielded acceptable growth of marine fish... |

| Three nutritional experiments were carried out to investigate the effect of dietary phosphatidylcholine (PC) on the growth (length, weight, and metamorphosis) and survival (rearing and stress) of larval and postlarval <i>Penaeus japonicus</i> Bate. Purified soybean phosphatidylcholine (SPC, 95% purity), hen-egg PC (EPC, 94% purity), and de-oiled soybean lecithin (DSL, PC 23% purity) were used as sources of dietary PC. The results indicated that optimal metamorphosis in larval <i>P. japonicus</i> was obtained at levels of 15-30 g kg<sup>-1</sup> of dietary SPC. Feeding trials with postlarval <i>P. japonicus</i> showed that low levels of dietary SPC (15 g kg<sup>-1</sup>) were more beneficial than... |

| Juvenile <i>Tapes philippinarum</i> (Adams and Reeve) were reared for three weeks on different rations of <i>Chaetoceros neogracile</i> which were either centrifuged and stored or fed together with the culture medium. Algal rations were adjusted daily in order to feed constant weight-specific daily rations. Growth of <i>T. philippinarum</i> fed the concentrate of <i>C. neogracile</i> was maximal at a daily ration of 1% (algal dry weight per clam live weight). <i>T. philippinarum</i> fed single or mixed diets of <i>C. neogracile</i> and <i>Isochrysis</i> sp. (clone T-Iso) directly from the algal cultures, maximized growth at a ration of 1,3% day <sup>-1</sup>.... |

| Dietary phospholipids and particularly phosphatidylcholine have been found to enhance growth and survival in penaeid shrimp, an effect which has been attributed to their limited ability to synthesize phospholipids de novo. However, most of the studies made so far have used low purity phospholipids and therefore, precise requirements for dietary phosphatidylcholine among several species of shrimp have been difficult to establish.As part of a broad study which aims to study lipid nutrition in penaeid shrimp, the dietary effect of purified phosphatidylcholine (PC) on growth, survival, stress resistance and body lipid composition of post-larval <i>Penaeus vannamei</i> fed semi-purified microbound diets was evaluated. Changes on the body lipid... |

| Lipids, particularly triglycerides, play an important role in early life stages of bivalves as a source of energy and essential fatty acids. Ingestion and incorporation of the fatty acids supplied through lipid emulsions were verified analytically for larval oysters <i>Ostrea edulis</i>. Changes of the fatty acid composition, in particular of (n-3) highly unsaturated fatty acids (n-3 HUFA), were demonstrated in total lipids, polar lipids and triglycerides of oyster larvae fed the lipid emulsions as a supplement to <i>Isochrysis galbana</i> (clone T-Iso), and were dependent on the level and proportion of (n-3) HUFA present in the emulsion. Preliminary culture trials with <i>Mercenaria mercenaria</i> showed better growth... |

| 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... |
