Evaluation of anchovy biomass, laying area and daily egg production in the Bay of Biscay
-
Evaluation of anchovy biomass, laying area and daily egg production in the Bay of Biscay
-
Acoustic fishing campaign for the evaluation of anchovy biomass, biological condition, hydrographic conditions and spatial distribution in the Bay of Biscay
-
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

Estimación de índice de abundancia anual de juveniles de anchoa (Engraulis encrasicolus) y caracterización de las condiciones ambientales para predecir magnitud del reclutamiento para el año siguiente.
-
Cartographic survey, obtaining seismic profiles and knowledge of the nature of the bottom of the continental shelf.
-
Annual estimate of the abundance of anchovy juveniles (Engraulis encrasicolus) in the Bay of Biscay through acoustic methology and study of spatial distribution and growth status during that time of year. With the results obtained, this campaign aims to estimate the 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
-
Detailed and systematic acquisition of bathymetry through the use of high resolution multi-beam echo sounder.
-
Monitoring of eutrophication. The project is carried out in combination with the B / O Odón de Buen develops other TROFOALBORAN campaigns in the Alboran Sea area focused on trophic studies.
