? Estimation of the abundance of small pelagic fishes, with special focus on anchovy juveniles, in the southern part of the Bay of Biscay.\n? Cartography of the distribution of these populations.\n? Study of the distribution of anchovy and sardine eggs.\n? Biological sampling of the species of interest (e.g. ). Particularly for anchovy, analysis of stomach contents for the characterisation of the food regime and of otholits for the study of daily growth rates.\n? Continuous sampling of auxiliary variables for the characterisation of the ambient environment.\n? Study of the hydrographic conditions and distribution of plankton components in order to define the physical and biological processes which are relevant for the regulation of the species of interest.

Estiamtion of the abundance of pelagic fish present in the North-east Atlantic waters in spring which is the spawning period for these fish species, but focussing in sardine and anchovy. Complementary to this main objective the survey design and strategies will allow the enviroment be characterised by recording differente variables (i. e. temperature, salinity, fluorescence, plankton, winds or air temperature) in vertical and horizontal profiles along the surveyed area with no noticeable extra-effort. As it was pointed out, these variables will help the acoustic estimations be improved whilst an extensive environment characterisation at the spawning time will be done.
