World Tuna Day 2023: On May 2, coastal regions around the world celebrate World Tuna Day every year. To conserve tuna stocks around the world and contribute to the development of sustainable fishing patterns, communities of fishermen, scientists and environmentalists have worked together to achieve this day. Because it is an important animal for human nutrition and economy.
According to a report by the Food and Agriculture Organization of the United Nations, most of the tuna stocks have been exhausted because of the inability to expand the catch and some have been overexploited, meaning in danger of depletion. The International Seafood Sustainability Organization estimates that 13% of tuna stocks are overfished, while 65% of stocks are in healthy abundance.
In resolution 71/124 in December 2016, the United Nations General Assembly officially decided to observe the event. And this campaign highlights the importance of conservation managers to ensure they have the necessary mechanisms and tools to stop the decline of tuna stocks.

About Tuna
Tuna is a speed-oriented, streamlined and elegant fish. It has two separate but closely spaced upper dorsal fins; the first fin is “squeezable” and can flush into a slot running along its back; It is supported by spikes. From the dorsal fin to the caudal fin, there are seven to ten yellow fins, curved and tapering to the tip. The ventral fin of a tuna is located below the base of the pectoral fin. When a fish swims fast, both the dorsal and pelvic fins retract.
