| This study examines the effects of varying dietary lipids on growth, survival, lipid composition and behaviour in lobster Homarus americanus (Milne Edwards, 1837) postlarvae. Lobsters were fed one of 3 diets during their early ontogeny: (1) Artemac, a widely used Artemia replacement; (2) a ternary mixture consisting of Artemac, frozen Artemia adults and Artemia flakes; or (3) a mixture of live A. salina nauplii and adults. We evaluated the olfactory capacity (response to predator odour plume) and cryptic behaviour (ability to hide during settlement) of lobster postlarvae as a function of these diets and the lipid and the fatty acid composition of lobsters. Growth and survival of lobster postlarvae were highest in those fed live Artemia, followed by the... |

| En los laboratorios de producción de postlarvas de camarón se suministra, en los estadios de protozoea y mysis, alimento vivo para garantizar buenos resultados en el cultivo sin embargo, el empleo de alimentos artificiales posibilita reducir la costosa dependencia de las algas y los quistes de Artemia ( Wouters et al, 2004). Aunque los resultados alcanzados con diferentes dietas artificiales en el cultivo larval son satisfactorios, aún existe gran preferencia por la utilización del alimento vivo. Sin embargo, en los últimos años con vistas a disminuir los costos de producción, la contaminación y agilizar el proceso productivo, diferentes empresas se han dado a la producción de alimentos artificiales para sustituir parcial (Fegan, 1992) o totalmente el... |

| HPLC techniques were adapted and standardized for quantification of ascorbic acid (AA) and its derivates in both diets and target organisms. To assess the dietary needs for AA at start of exogenous feeding, the AA content in the various live diets currently used in aquaculture (algae, rotifers, <i>Artemia</i> ) was analyzed. Application of techniques for boosting vitamin C using ascorbyl palmitate as the source enabled the transfer of elevated levels (up to 2,500 µg AA/g DW) of bioactive vitamin C. Larvae of fish (<i>Clarias gariepinus, Dicentrarchus labrax, Scophthalmus maximus</i>), white shrimp (<i>Penaeus vannamei</i>) and prawn (<i>Macrobrachium rosenbergii</i>) were enriched via the live food chain.... |

| 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... |
