| Poucos estudos apresentam interações entre a fisiologia das plantas e sua posterior composição química, quando cultivadas em diferentes arranjos. Esta pesquisa buscou compreender a relação entre o espaço de cultivo da soja e sua influência sobre a qualidade da semente. Foram estudadas duas cultivares de soja (Tec 7849 Ipro e Monsoy 6972 Ipro) em quatro arranjos espaciais distintos (50,0 x 7,1; 40,0 x 8,9; 30,0 x 11,9 e 18,9 x 18,9 ou 16,2 x 16,2 cm, respectivamente). Durante os estádios fenológicos V4 e R2, foram analisadas trocas gasosas e na colheita, foram constituídos 2 grupos, um de sementes frescas e outro de sementes envelhecidas, para ambos os grupos se analisaram: teste de germinação, vigor, índice de velocidade de germinação, massa fresca das... |

| A México se le considera centro de origen del zapote mamey ya que cuenta con una gran diversidad. Sin embargo, son pocos los trabajos enfocados en estudiar tal diversidad tanto en la parte morfológica, contenido de ácidos graso o aspectos moleculares. Por lo anterior, el objetivo del presente trabajo fue: caracterizar morfológica, bioquímica y molecularmente selecciones sobresalientes de zapote mamey. En base a las variables de fruto y el perfil de ácidos grasos en semilla, el material vegetal estudiado mostró amplia variación entre las accesiones. El peso y longitud de fruto, longitud de hilio y de semilla, número de fibras, grosor de epicarpio y ancho de semilla fueron las variables determinantes para la agrupación de las selecciones. El perfil de... |

| The goal of this study was to evaluate the effects of seasonal variations on energy metabolism in different tissues of the freshwater crayfish Parastacus brasiliensis (von Martens, 1869). Crayfish were collected monthly from January 2001 to January 2003 in São Francisco de Paula, Rio Grande do Sul, Brazil, in a stream and in a culture tank. Haemolymph samples were collected from each crayfish in the field with a syringe, by puncturing the membrane at the base of the chelipeds. Hepatopancreas, gills, and abdominal muscle were removed for determination of free glucose, glycogen, total lipids, and triglycerides. The haemolymph samples were used for determination of glucose, total proteins, total lipids, and triglycerides. Statistical analysis revealed... |

| While focus in oil-producing microalgae is normally on nutrient deficiency, we addressed the seasonal variations of lipid content and composition in large-scale cultivation. Lipid content, fatty acid profiles and mono- di- and triglycerides (MAGs, DAGs, and TAGs) were analyzed during May 2007-May 2009 in Nannochloropsis oculata grown outdoors in closed vertical flat panels photobioreactors. Total lipids (TL) ranged from 11% of dry weight (DW) in winter to 30% of DW in autumn. 50% of the variation in TL could be explained by light and temperature. As the highest lipid content was recorded during autumn indicating an optimal, non-linear, response to light and temperature we hypothesize that enhanced thylakoid stacking under reduced light conditions resulted... |

| The main objective of this study is the valorisation of by-products coming from processed tuna (Thunnus albacares). Therefore, enzymatic hydrolysis was selected, using an industrial large spectrum protease (Protamex). In a first phase, hydrolyses of these by-products (heads, tails, viscera) were carried out for long periods of time (12h) in order to establish the kinetics of the proteolysis of those different by-products and to obtain the approximate composition of the different resulting fractions and to determine the conditions which would allow the valorisation of these fractions. In a second phase the valorisation in animal nutrition (shrimp culture) and in human nutrition (fish sauce) of the fractions coming from the hydrolysis of the head of tunas... |

| Proximate biochemical analysis (proteins, lipids and carbohydrates) are performed on a regular basis by the various laboratories fom the Aquaculture Resources Directorate. Methods initially developed to analyse hydrological parameters were firstly transfered to assess meat components.1t appears now important to review and update the commonly used methods (Lowry et al., (1951), Dubois et al.,(l956), Marsh et Weinstein, (1966)), for our specifie purposes. A round table was organized to facilitate discussion among researchers and technicians from both Directorates 'Aquaculture Resources' and 'Product Valorization'and external partners, University of Caen. Several communications reviewing former and recent studies were done. Colleagues from the Directorate... |

| If rays are traditionally fished for their caudal fins, the rest of the body is wasted, except part of the skin that can be transformed into leather. Liver oil of the ray, Himantura bleekeri, was characterized in terms of lipid class composition and fatty acid profile. Liver oil content was high and represented 54% of the liver weight (w/w). Neutral lipids were predominant (92%), major components being triacylglycerols (63%). Other neutral lipids identified were hydrocarbons, sterol esters, mono- and di-acylglycerols, free fatty acids, sterols and glyceryl ethers. Polyunsaturated fatty acids of the n-3 series, namely eicosapentaenoic and docosahexaenoic acids, were high (4% and 16%, respectively). Cholesterol was the major component in the sterol fractions... |

| In summer 1979, the natural reproduction of oysters Crassostrea gigas Thunberg, in Marennes-Oleron basin, produced a large number of juveniles which was not the case in summer 1981. If one compares the evolution of the main constituents of the flesh, one can see that, at the beginning of August, before spawning the male oysters in 1981 contained 6,3% less proteins, 34,2% less lipids and 61,2% less glucids than those in 1979 and respectively 12,3%, 21,3% and 69,8% less as far as females are concerned. The energetic value of ash-free dry flesh of female oysters is nearly the same for the two years whereas for male oysters the value is slightly lower in 1981 than in 1979. The total energetic values of male and female oysters show a slight difference between... |

| Tisochrysis lutea is a microalga species currently used in aquaculture as a feed for shellfish, oysters and shrimps. It also has many other potential industrial applications, such as the production of neutral lipids for biofuels or the production of ω-3 fatty acids for nutraceuticals (human food complements). To efficiently exploit the potential of this microalga, however, higher lipid productivities are needed. To this end, improvement programs need to be developed and optimized. The diversity of strains available in microalgae has not yet been exploited in such improvement programs. In this study, the intra-strain diversity was observed and exploited to increase neutral lipid productivity. New clonal strains with higher neutral lipid productivity were... |

| Xenophyophores, widespread giant deep-sea protists, dominate the megafaunal organisms visible on the seafloor in some areas. Owing to the extreme fragility of their tests (external part), little is known about them, and their diet is largely a matter of speculation. The extensive accumulation of fecal pellets (stercomes) within their tests attests to the degree to which xenophyophores feed on particulate matter. During the EUMELI 2 cruise, xenophyophores were recovered intact at the surface of box-cores from an abyssal mesotrophic site in the northeastern Atlantic. They were identified as Syringammina corbicula. In our study, we compare the lipid composition of xenophyophores collected at the top of cores with sediment from the same mesotrophic environment... |

| We investigated links between swimming behavior and muscle bioenergetics in two emblematic Mediterranean fish species that have very different ecologies and activity levels. European sardines Sardina pilchardus are pelagic, they swim aerobically, school constantly and have high muscle fat content. Gilthead seabream Sparus aurata are bentho-pelagic, they show discontinuous spontaneous swimming patterns and store less fat in their muscle. Estimating the proportion of red and white muscle phenotypes, sardine exhibited a larger proportion of red muscle (~10% of the body mass) compared to gilthead seabream (~5% of the body mass). We firstly studied red and white muscle fiber bioenergetics, using high-resolution respirometers, showing a 4-fold higher oxidation... |

| A review of lipid requirements of shrimp and other crustacean species, when applicable, is presented. Qualitative requirements of crustaceans for cholesterol, fatty acids and phospholipids have been documented, but quantitative requirements generally remain undefined. Potential interrelationships between different classes of lipids that may influence requirements as well as differences due to age and species need to be investigated. A more accurate definition of lipid requirements can be achieved by supporting traditional evaluations based upon weight gain and survival with biochemical or histological evidence. |
