SUMMARY:The project PLATERIAS financed by Xunta de Galicia in its sectoral program of Tecnoloxias Ambientais has as objective the study of the physical oceanography of the continental shelf and rias of Galicia by means of the development and integration of the existent observation network and the demonstration of the feasibility of the modelizacion of the dynamics of the rias of Galicia and the adjacent shelf by means of a hydrodynamic model coupled to a meteorological mesoscale regional and local high resolution model. This campaign is intended to contribute to the knowledge of the interaction between the rias and the shelf. OBJECTIVES:-To study the interaction between the rias and the shelf, particularly in the Ria de Ares.- Recovery a mooring in the channel in order to characterize the incoming and outgoing flow of the ria.- Performance of transects of CTD profiles across the main channel in the mouth of the ria to characterize the ria-shelf exchanges.

CR PELACUS 0405 Give an improved 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. This year there was in use for the first time an Laser Optical Plankton Counter (LOPC), in collaboration with investigators of the IFREMER. Also sampling of sardine for the estimation of parameters of fecundity necessary for the application of the MPDH.

? 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.
