World Tuna Day

World Tuna Day is a global observance focused on sustainable fishing and public awareness about tuna and marine conservation. Tuna are widely distributed, play an important role in ocean ecosystems, and provide food and livelihoods in many parts of the world. World Tuna Day is observed annually on May 2.

History of World Tuna Day

World Tuna Day was established in 2016 by the United Nations General Assembly. The observance was created to highlight the ecological and economic importance of tuna and to encourage long-term, sustainable management of tuna stocks worldwide.

Tuna are highly migratory fish that can travel long distances across oceans. Their physiology allows certain species to maintain body temperatures higher than the surrounding water, which supports movement through colder regions and contributes to their wide range.

As demand for tuna increased, advances in fishing technology made it easier to catch larger quantities. This contributed to overfishing in some areas and increased the need for international monitoring and cooperation. World Tuna Day emphasizes responsible fishing practices and ongoing conservation efforts to help protect tuna populations and the ecosystems that depend on them.
