PELACUS Give an improved estiamtion of the abundance of pelagic fish present in the NE 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. t/S, 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. - ref 0403

CR PELACUS 0404 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. (French 20050099/ref 4030270)
Caracterizacion fisica, biogeoquimica y de produccion planctonica Estudio de los frentes costeros que delimitan los ambientes.
Oceanographic survey collected in the framework of the following research project: 'Metodos de Produccion de Huevos. Estimacion de la biomasa de especies pelagicas de interes comercial: sardina, anchoa, caballa y jurel (ICTIOEVA)'. This Project is funded by the Instituto Español de Oceanografia and the main scientific objective is to produce an index and a direct estimate of the spawning stock biomass of Sardine (Sardine pilchardus) in the Cantabrian Sea and Bay of Biscay (to 45°N) using the Daily Egg Production Method (DEPM). Specific aims:a) To estimate the spawning area distribution of sardine and the daily egg production. b) To collect adults to obtain fecundity estimation c) Distribution and abundance of other commercial species of interest: mackerel, horse mackerel and anchovy.d) To describe the oceanographic and meteorological character of the area of study with the aim of relating environmental conditions (temperature, salinity, currents) with the spatial distribution of the ichthyoplankton
