World Tuna Day

A United Nations day on 2 May for the tunas, among the most valuable and most fished fish in the world.

The United Nations General Assembly set 2 May as World Tuna Day in 2016, at the request of Pacific island states whose waters hold much of the world's tuna catch. Tunas are fast, warm-bodied fish of the open ocean, and the catch of skipjack, yellowfin, bigeye, albacore and the bluefins runs to several million tonnes a year. The day draws attention to the regional bodies that set catch limits and to the problems of illegal fishing and bycatch, the sharks, turtles and young fish caught by mistake.

Still to be written: Skipjack tuna, Yellowfin tuna, Bigeye tuna, Albacore, Pacific bluefin tuna.
