L'étude de la population de thon blanc du Nord-Est atlantique et ses incidences sur l'exploitation

The studies conducted recently on albacore enabled a number of conclusions to be drawn which can be used straight away and are of great economical importance as far as fishery is concerned. Tunas are great migrants: a bluefin tuna marked on the American Atlantic coast was captured again 55 days later in Norway. Pacific Albacores actually travel between the U.S.A and Japan... Evidence of these trips abound: they travel oceans in search of specific ecological conditions that are themselves in constant evolution.
