-
Study of the Spanish continental shelf. Cartographic survey, obtaining seismic profiles and knowledge of the nature of the fund from high-resolution geophysical techniques using dredgers
-
Cartographic survey of the proposed work areas, together with seismic studies and sampling of the seabed.
-
Estimation by pelagic trawling and acoustic methods of the biomass index and population and biological parameters of anchovy (Engraulis enrasicolos) (and Sarina pilchardos sardine, as a secondary objective), to evaluate the state of the fisheries. In the pelagic trawling, the Daily Egg Production Method (MPDH) is applied as an estimate of the biomass. Study of the influence of the hydrographic variables of the water column (temperature, salinity and chlorophyll)
-
Cartographic survey, obtaining seismic profiles and knowledge of the nature of the bottom of the continental shelf
-
Assessment of the status of benthic communities and populations of cephalopods and fish in the rocky infralitoral.
-
Annual estimation of the abundance of anchovy juveniles (Engraulis encrasicolus) in the Bay of Biscay by acoustic methodology, and study of the spatial distribution and the state of growth during that specific time of the year. With the results obtained, this campaign aims to estimate an annual abundance index of juveniles that allows to infer each year the magnitude of the annual recruitment of anchovy that will enter the population the following year

Annual estimation of the abundance of anchovy juveniles (Engraulis encrasicolus), by means of acoustic methodology and study of the spatial distribution and the state of growth during that specific time of the year. With the results obtained, this campaign seeks as an ultimate goal, to estimate an annual abundance index of juveniles that allows to infer each year the magnitude of the annual recruitment of anchovy that will enter the population the following year.
-
Study of the characteristics and configuration of the existing seabed in the marine reserves of the Menorca Channel as well as the Sites of Community Importance (SCI) located in its surroundings
-
Annual estimate of abundance of anchovy juveniles in the Bay of Biscay
-
Evaluation of anchovy biomass, laying area and daily egg production in the Bay of Biscay
