Campaña: ECOMARG 1003

From day 6 to day 21 of the month of October the B / O Vizconde de Eza made the first of a series of multidisciplinary campaigns aimed at improving knowledge of El Cachucho fishing ground, located on the Asturian marginal shelf within the Spanish EEZ. This fishing ground is characterized by being a very irregular zone, presenting slopes greater than 45 degrees in some areas. The study of benthic communities and demersal fish was supported by exhaustive studies of other disciplines in order to obtain information about their environment and existing trophic relationships. The results obtained, and analyzed separately, of each discipline are of great value due to the unique characteristics of the fishing ground, but the common effort of the participants to relate all the subjects adds to the campaign an incalculable value in the scientific field and unique knowledge for the management of the fishery in the current framework that advocates sustainable development. GOALS Due to the scarce bathymetric information in the fishing grounds, the first part of the campaign focused on obtaining an accurate bathymetry of the study area that served as the basis for the physical, chemical, geological and biological studies that the different participating teams carried out. then. WORK AREA Image of the work area comprising the upper part of the Le Danois bank and the area between this elevation and the Lastres canyon The bank's funds are difficult to access, due to their depth and relief, for most of the instruments that come into contact. This limits the area of the study area. Mainly the works were oriented to the upper part of the bank Le Danois and to the area between this elevation and the Lastres
