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.

Abundance indices, distribution patterns and faunal assemblages of demersal species in the Flemish Cap bank, together with the possible driving factors of their distribution. This survey belongs to the research project: 'Biología Pesquera pesquerías Lejanas'. This Project is partly funded by the DCR of the EU and the Education and Science Spanish Ministery. T The main objectives of the above mentioned project related with this survey time series are: a) to obtain abundance indices of the main exploited species in the Flemish Cap bank b) to estimate the strength of yearly recruitments of these species and their distribution in the bank. c) to study the structure and distribution o the demersal and benthic communities in the area

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.

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.

Within the framework of cooperation between the Ministry of Agriculture, Fisheries and Food (MAPA) and the Ministry of Fisheries of the Republic of Angola, the campaign to evaluate the main species of crustaceans and other demersal resources of existing fishing interest was undertaken on the platform and slope of the Exclusive Economic Zone of the Republic of Angola. WORK AREA The investigation was developed in the area of ​​the platform and the slope of the Exclusive Economic Zone of the Republic of Angola between the parallels 5º S and 12º S, from 12 miles from the coast, counted from the baseline, to the Isobot of the 800 meters deep.
