    The surveys on NAFO Regulatory Area of Div. 3L (Flemish Pass) were initiated by Spain in 2003. The surveys were carried out by the R/V 'Vizconde de Eza' following the same procedures and using the same bottom trawl net type Campelen.The main objectives of this survey time series are: a) to obtain abundance indices of the main exploited species, b) to study the structure and distribution of these demersal species in the area.

    Coinciding with the development of the project, Friday, April 2, 500 days have passed since a 26-year-old monocoque tanker, loaded with 77,000 tons of fuel, split in two. The Prestige sank 260 km from the Cies Islands, in the Vigo estuary, generating a first spot of 5,000 tons of fuel. This campaign analyzes the effects produced by the spillage of the Prestige hydrocarbon on the ecosystem of the continental shelf of Galicia. OBJECTIVES Multidisciplinary campaign that monitored the impact of oil spills on demersal and benthic communities in funds between 70 and 500 m. Likewise, the geophysical study of the worst known areas of the platform was undertaken, such as the rocky areas, which are, nevertheless, of great ecological and commercial importance, and possible areas of sedimentary deposit that can be points of accumulation and retention of fuel

    From day 12 to day 31 of the month of April 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. Morpho-sedimentary study of the "El Cachucho" fishing ground and adjacent area. Dynamics and characteristics of water bodies. Characterization of benthic and demersal communities.

    Annually, the European Union develops two research campaigns in the area of ​​NAFO (North Atlantic Fisheries Organization), one in the 3NO division and another in the 3M and 3L (Flemish Cap Series). This campaign is part of a historical series in order to provide indices for the evaluation of the stock of halibut and other groundfish species in the area such as flounder, redfish, grenadier, cod or shrimp. The Flemish Cap bank is an isolated bank of the American coastal platform with an area greater than 10,000 square miles and is located outside of the Exclusive Economic Zone of Canada. The exploitation of the resources of this area is regulated by the international agreements of NAFO. GOALS Estimation of abundance and biomass indices of the target species, as well as the study and analysis of the demographic structure of their populations and the oceanographic conditions in the Bank.

    The Algerian continental shelf, very narrow and rocky, is not conducive to bottom trawling. Its average length is 6 km, even in certain areas, the 500-meter isobath is 3 miles from the coast. Only in some gulfs in the west of the country (such as Oran), near the Alboran Sea, the platform reaches an extension above average. According to the Algerian Geographic Unit, it is estimated that only 1/3 of the surface is optimal for bottom trawling: 3,500 km2 up to 200 m depth and 7,000 km2 between 200 and 350 m. This limits the availability of demersal species and thus, rg / 1999 / xhtml "> of the total catches of these species (~ 25,000 Tm), about 4,000 (~ 20%) correspond to crustaceans, mainly prawns, which are caught between 200 and 400 m GOALS Determine the abundance and characteristics of the main demersal resources of Algeria. For this, the following partial objectives are proposed: - Know the biological structure of the communities exploited by the trawl fishery on the platform and the upper slope. - Obtain indices of abundance and biomass of the main species, such as mullet, sparids, hake, monkfish, white shrimp, Norway lobster, pink prawn, Moorish prawns, octopus and cuttlefish. - To determine the characteristics of the demographic structure of these species, as well as to know their geographical and bathymetric distribution. - Collect data on the state of maturity, size and weight, and collect biological samples of demersal species for growth and reproduction studies.
