Genetic Analysis of the Fatty Acid Profile in Gilthead Seabream (Sparus aurata L.).

The gilthead seabream is one of the most valuable species in the Mediterranean basin both for fisheries and aquaculture. Marine fish, such as gilthead seabream, are a source of n3 polyunsaturated fatty acids, highly appreciated for human food owing to their benefits on the cardiovascular and immune systems. The aim of the present study was to estimate heritability for fatty acid (FA) profile in fillet gilthead seabream to be considered as a strategy of a selective breeding program. Total of 399 fish, from a broodstock Mediterranean Sea, were analysed for growth, flesh composition and FA profile. Heritabilities for growth traits, and flesh composition (fat, protein, and moisture content) were medium. Heritability was moderate for 14:0, 16:0 and 18:1n9 and for sum of monounsaturated FA and n6/n3 ratio, and it was low for 20:1n11 and 22:6n3 and the ratio unsaturated/saturated FA. Breeding programs in gilthead seabream usually include growth as the first criterion in the selection process of the fish. However, other quality traits, such as fillet fat content and its fatty acids profile should be considered, since they are very important traits for the consumer, from a nutritional point of view and the benefits for the health.Versión del edito

Ejemplificaciones de proyectos de educación infantil

Ejemplificaciones de proyectos curriculares de educación infantil contextualizado en cuatro centros de educación infantil: La Luna, escuelas municipales de Puerto Real, Giner de los Rios de Córdoba y Sancho Panza de Granada. Cada proyecto curricular se estructura de una forma independiente según sus propias características, pero todos tienen una contextualización, unas señas de identidad de la escuela, unos objetivos generales, contenidos, metodología, evaluación y bibliografía.AndalucíaBiblioteca de Educación del Ministerio de Educación, Cultura y Deporte; Calle San Agustín 5 -3 Planta; 28014 Madrid; Tel. +34917748000; [email protected]
