    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

    The oceanographic vessel Vizconde de Eza developed its first research campaign in Galicia as a result of the unfortunate accident and sinking of the Prestige oil tanker. In January of 2003, this project was undertaken to estimate the impact produced by the discharge of hydrocarbon on the demersal communities on the continental shelf of Galicia, in soft bottoms between 90 and 500 m, testing new acoustic methods for the detection of fuel the depths fixed. This multidisciplinary campaign took place over eight days on board the B / O Vizconde de Eza in the area of ​​the continental shelf between the Ría de Muros and La Coruña. The study of the main members of the bottom communities (infauna, epifauna, suprabenths and benthic and demersal macrofauna) was included, for which 20 sampling stations were established located in the three strata of the standardized trawl campaigns (70 - 120, 121 - 200 and 201 - 500 meters).

    This campaign to evaluate deep demersal resources on the coasts of Algeria responds to the need to update and expand the studies and evaluations carried out in the 1980s. During this fishing prospecting campaign, 55 catches were made between 200 and 800 meters deep, using bottom trawls. To determine the abundance and properties of the main fishing resources of Algeria, it was necessary to obtain prior knowledge of the characteristics of the seabed on the sampled fishing beaches. Likewise, the precise knowledge of the bathymetry and morphology of the bottom optimized the trawl work and, in short, the achievement of the fishing campaign. GOALS Image of ship's personnel releasing trawl - Bathymetric and morphological recognition of the seabed in the upper slope and the Algerian coast. - Know the biological structure of demersal communities subjected to exploitation in the upper and middle slope of the study area. - Obtain indices of abundance and biomass of the main deep demersal species (hake, monkfish, white prawn, Norway lobster and red shrimp). - Characterize the demographic structure of the main demersal species exploited on the slope, as well as its geographical and bathymetric distribution. - Collect data and collect samples (otoliths) from deep demersal species for growth and reproduction studies. WORK AREA The bathymetric surveys were carried out at night, in such a way that sufficient time was available to elaborate the bathymetric maps and digital terrain models. This allowed the selection of the haul zones and served as an electronic cartography for navigation.
