Combined effects of dietary HUFA level and temperature on sea bass (Dicentrarchus labrax) larvae development ArchiMer
Vagner, Marie; Robin, Jean; Zambonino, Jose-luis; Person, Jeannine.
The purpose of this study was to investigate the combined effect of the incorporation of vegetable products in diet and temperature on enzymatic pathways for high unsaturated fatty acids (HUFA) desaturation in sea bass larvae. Four replicated groups were fed a low (LH; 0.8% EPA+DHA) or a high (HH; 2.2% EPA+DHA) n-3 HUFA microparticulated diet from mouth opening, six days post-hatching and were reared at 16 or 22 degrees C. The four experimental conditions (LH16, HH16, LH22 and HH22) were tested for 45 days. At the end of the experiment, body weight, total length and biomass were affected by temperature (P<0.001), while biomass as well as fresh body weight was also influenced by diet (P<0.05 and P<0.001 respectively). This always lead to the same...

CRECIMIENTO Y SUPERVIVENCIA DE LARVAS DE ARGOPECTEN NUCLEUS ALIMENTADAS CON DIFERENTES DIETAS MICROALGALES* Boletín de Investigaciones
Carreño Hernández,Yenia Katerine; Acosta Ortiz,Ernesto; Gómez-León,Javier.
Se estudió la influencia que ejerce la dieta sobre el desarrollo larvario del pectínido Argopecten nucleus, probando seis dietas microalgales compuestas por dietas monoalgales y mezcla de las especies Isochrysis galbana, Chaetoceros calcitrans y Tetraselmis suecica en relación 1:1, manejando una concentración por mL equivalente al peso de 40000 células de I. galbana, midiendo la respuesta a través de las variables supervivencia, crecimiento, aparición de la mancha ocular y estado de condición (larvas llenas, semillenas y vacías). Las dietas que contenían I. galbana presentaron los mayores valores en cada una de las variables medidas, en comparación con aquellas que carecían de esta. Particularmente, la dieta mixta I. galbana + C. calcitrans presentó...

Effect of diets containing different levels of highly unsaturated fatty acids on physiological and immune responses in Pacific whiteleg shrimp Litopenaeus vannamei (Boone) exposed to handling stress ArchiMer
Mercier, Laurence; Racotta, Ilie; Yepiz-plascencia, Gloria; Muhlia-almazan, Adriana; Civera, Roberto; Quinones-arreola, Marcos F.; Wille, Mathieu; Sorgeloos, Patrick; Palacios, Elena.
Juveniles fed a diet containing a low or a high level of highly unsaturated fatty acids (HUFA) for 38 days were exposed to handling stress. In a first experiment, stress was applied daily for 30 days, after which the physiological and immunological variables were measured, whereas in a second experiment, stress was applied once and samples were obtained 1 and 24 h after the stressor event. Shrimp that were stressed for 30 days showed significantly lower survival, final weight and feed consumption compared with unstressed shrimp. The concentration of the high-density lipoprotein beta-glucan-binding protein was significantly higher in shrimp fed the high-HUFA diet. The glucose concentration in the haemolymph was significantly higher in long-term stressed...

Incorporation of dietary fatty acid in European sea bass (Dicentrarchus labrax) - A methodological approach evidencing losses of highly unsaturated fatty acids ArchiMer
Robin, Jean; Skalli, A.
A quantitative approach is presented to evaluate fatty acid incorporation in fish. Fatty acid composition of European sea bass juvenile was studied during an experiment using 6 isoproteic (54%) and isolipidic (18%) diets containing 0.23, 0.56, 0.72, 0.86, 1.01 and 1.86% DM n-3 highly unsaturated fatty acids (n-3 HUFA). Whole body fatty acid compositions were studied at the beginning and after 52 and 81 days feeding, fatty acid profiles evolved during time under dietary influences. Incorporations of individual fatty acids into total lipids were calculated as increases in individual fatty acids as percentages of the increase in total fatty acids during growth, on a per animal basis. Relative incorporations (RI) so defined generated similar profiles for the...

Is it possible to influence European sea bass (Dicentrarchus labrax) juvenile metabolism by a nutritional conditioning during larval stage? ArchiMer
Vagner, Marie; Zambonino, Jose-luis; Robin, Jean; Person, Jeannine.
The purpose of this study was to check if it is possible to influence sea bass juvenile metabolism by a conditioning of larvae from day 6 post hatching to day 45 to a low or a high HUFA compound diet (LH, 0.8% EPA + DHA and HH, 2.2% EPA + DHA) when reared at 16 or 22 °C. Following a 3-month intermediate period (at 19 °C using a commercial diet), the adaptability of the 4 initial larval groups to a HUFA experimental deprived diet (0.5% EPA + DHA) were tested at 19 °C in a 60 day-experiment (d-151–211). The four experimental duplicated conditions were ex-LH16 and ex-HH16 for the 2 groups previously reared at 16 °C (initial weight, 7.3 ± 0.5 g) and ex-LH22 and ex-HH22 for the 2 groups previously reared at 22 °C (initial weight, 11.1 ± 0.5 g). Survival was...

Lipid composition of the giant lion's-paw scallop (Nodipecten subnodosus) in relation to gametogenesis - I. Fatty acids ArchiMer
Palacios, Elena; Racotta, I; Kraffe, E; Marty, Y; Moal, Jeanne; Samain, Jean-francois.
Seasonal variations in fatty acid composition in several tissues of a 1-year-old population of giant lion's-paw scallop Nodipecten subnodosus were analyzed during gonad development. Samples were taken bimonthly from December 1999 to June 2000, a period in which gonad development was occurring. Fatty acid accumulation in neutral and polar lipids of the female gonad was concomitant to the gonad development and presented a maximum in June. Among essential fatty acids, a specific accumulation was observed only for 20:5n - 3 in the female gonad, as suggested by an increase in its proportion in the neutral and the polar fractions. However, no specific accumulation was observed for 22:6n - 3, as its proportion remained relatively constant in both fractions. We...
