Campaña: ARGELIA 0204

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.
