Give an improved estimation of the abundance of pelagic fish present in the North-east Atlantique 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 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.
