This paper reviews historical trends of the catches of the major commercial species (albacore, bigeye, bluefin, skipjack and yellowfin) of tunas. The total world catch of these species has increased during the last 50 years (from to million tonnes), but the pattern of increase has varied among species, oceans and fishing gears.
This paper reviews historical trends (mostly ) of the catches of the major commercial species of tunas in the world (albacore, bigeye, bluefin, skipjack, and yellowfin).
The total world catch of these species has increased continuously and almost tenfold during the last 50 years (from to million metric tons), but the pattern of increase has varied among species, oceans and fishing.
