HUFA content and DHA/EPA improvements of Brachionus plicatilis for sea bream (Sparus aurata) larvae

The relative concentration of n-3 and n-6 fatty acids and the DHA/EPA ratio are important factors in the survival and growth of marine larvae. The main objective of the present work was to campare the fatty acid content of one-day post-hatch sea bream larvae with the fatty acid content of severa1 di...

The main objective of the present work was to campare the fatty acid content of one-day post-hatch sea bream larvae with the fatty acid content of severa1 dietary enrichment products (Chlorella sp., Protein Selco and Super Rotifer) and Brachionus plicatilis after enrichment. Generally, enriched B. plicatilis are added to larval culture tanks and they remain the only source of nutrients for up to 12 h. It was therefore decided to also study the fatty acid profile of B. plicatilis 3, 6 and 24 h after enrichment. Some of the enrichment products were found to have a higher HUFA content than the sea bream larvae, but the ratio of DHA/EPA was always inferior. Brachionus plicatilis was rapidly depleted in HUFA 3 and 6 h after enrichment and after 24 h, B. plicatilis could not be considered enriched. La concentración relativa de los ácidos grasos n-3 y n-6 y la razón DHA/EPA son factores importantes para la supervivencia y crecimiento de larvas marinas. El objetivo del presente estudio fue comparar el contenido de ácidos grasos en larvas de pargo dorado de un día de edad con el contenido de ácidos grasos de varios productos alimenticios de enriquecimiento (Chlorella sp., Protein Selco y Super Rotifer) y con Brachionus plicatilis después de enriquecimiento. Generalmente, se añaden B. plicatilis enriquecidos a los tanques de cultivo larvario y son la única fuente de nutrientes por hasta 12 h. Por tal motivo, se decidió analizar el perfil de ácidos grasos de B. plicatilis 3, 6 y 24 h después de enriquecimiento. Se encontró que algunos de los productos de enriquecimiento presentaron un contenido de HUFA mayor que el de las larvas de pargo dorado, pero la razón de DHA/EPA siempre fue menor. El HUFA se redujo rápidamente en B. plicatilis 3 y 6 h después de enriquecimiento y después de 24 h, no se podía considerar a B. plicatilis como enriquecido.
