CTD data in the Flemish Cap area
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.
Annual estimate of abundance of anchovy juveniles in the Bay of Biscay during the months of September and October
Abundance index for the main demersal species of commercial interest to study the bathymetric distribution size / weight ratios
Study of the characteristics and configuration of the existing seabed in the Columbretes Islands Marine Reserve and Sites of Community Importance (SCI) in its environment

The ECOMED 2006 is an annual echosurvey for estimation of the abundance and biomass of small pelagic fish present in the Mediterranean Sea in autum, at the beginning of spawning period for the sardine (Sardina pilchardus) and the recruitmen period for the anchovy (Engraulis encrasicolus).These main species are sardine and anchovy, but on estimed also Sardinella aurita, Trachurus mediterraneus, T. trachurus, T. picturatus, Boops boops, Scomber japonicus and Scomber scomber. Complementary to this main objectives, also sampling for sardine fecundity parameters estimation. Continuous fish eggs sampling and temperature and salinity for sardine spawning area caracterisation.
