Campaña: ARGELIA 0303

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.
