En el presente estudio, una serie de pares de imágenes consecutivas del sensor Advance Very High Resolution Radiometer separadas entre si 24 horas son utilizadas con el objetivo de deducir velocidades de flujo superficial en el área del afloramiento del NW de África. El método utilizado es el método de las correlaciones cruzadas bidimensionales entre imágenes de satélite sucesivas, que representan el movimiento de las estructuras observadas. Los resultados de aplicar este método son analizados y discutidos. ABSTRACT In this study, some pairs of consecutive satellite images from the Advance Very High Resolution Radiometer (AVHRR) with a time separation of 24 hours are used in order to derive the sea surface flow velocities in the Northwest African up welling area. The method used is the Maximum Cross Correlation Method (MCC), and it consists in locate the maxima of bidimensional cross correlations between consecutive images. That maxima represent the movement of the observed features. The results are analyzed and discussed

[EN]The present work describes the procedures for capture, maintenance and evolution of a Pseudocaranx dentex stock in the Instituto Canario de Ciencias Marinas. Forty fish captured in a commercial off-shore fish farm, were transferred to on land facilities, acclimatation to tanks and inert food was successfully carried out, with 100% survival after 1 year. Initial fish weight (4,15kg) was , followed and sampled to determine individual growth in weight and size. Also, the evolution of its sexual maturity state was evaluated at capture and one year after to determine the maturation of fish for future juvenile production. Fish mature in captivity, but natural spawn was unsuccessful
