Exploitation des requins en Algérie

31 species belonging to 12 shark families have been reported in Algeria. Some species are regularly exploited by fishermen while others are accidentally caught by artisanal fisheries targeting swordfish and small tunas. Statistical data from landings in the commercial fishery for 2016 and 2017 revealed that the information collected does not give a precision on many landed species, especially those belonging to the genus Carcharhinus. The analysis of catch data from commercial fishing trips for large highly migratory fish carried out by Japanese longliners in waters under Algerian national jurisdiction between 2000 and 2009 for a period from the 15 April to 1 June, shows 3 families of sharks considered as associated fauna of bluefin tuna Thunnus thynnus. Also, a bibliographic synthesis reveals that the biological studies carried out in Algeria deal with the systematics, the ecology and the biology of the sharks caught in Algerian waters.
