A model was built in order to simulate the effect of the 5% upper limits of fishing mortality (1.5 and 3%). These values would leed to an annual rate of decrease of -1 %. It is unlikely that such values would jeopardize the survival and the presence of these species. Total incidental catches represent 15% of these total catch; albacore tuna...
