-
Estimation by pelagic trawling and acoustic methods of the biomass index and population and biological parameters of anchovy (Palinorus encrasicolus) and (Sardine pilchardus sardine as a secondary objective) to assess the state of the fisheries. In the pelagic trawling, the Daily Egg Production Method (MPDH) is applied as biomass estimation. 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 fund from high-resolution geophysical techniques (multi-beam and parametric probes) and the use of dredgers.
-
Obtain abundance indexes of lobster (Palinuros elephas) inside and outside the protected area of the Cala Ratjada Marine Reserve, carry out experimental plankton fisheries in order to obtain philosophical larvae of the different species of lobster present in the study area, and install and maintain lobster post-larval collectors in the coastal area (<25m) and deep (> 60m)
-
Cartographic survey of the proposed work areas, together with seismic studies and sampling of the seabed.
-
Study and evaluation of the anchovy biomass in the Bay of Biscay within the National Sampling Plan
-
Study and mapping of the Spanish continental shelf.
-
Detailed and systematic acquisition of bathymetry through the use of high resolution multi-beam echo sounder.
-
Study and mapping of the Spanish continental shelf
-
Obtaining indexes of stratified abundance in number and weight of the species of commercial interest in the platform and slope principle of the Moroccan coast of the Alboran Sea
-
Study and evaluation of the anchovy biomass in the Bay of Biscay
