Celebrated annually on May 2nd, World Tuna Day serves as a global reminder of the urgent need to protect and sustainably manage tuna stocks. With the 2025 theme “Our Ocean, Our Tuna, Our Future,” the focus is on the deep connection between healthy oceans and thriving tuna populations. It calls on individuals, communities, organizations, and governments to unite in safeguarding this essential resource.
Why World Tuna Day Matters
Tuna is more than a popular seafood — it’s a lifeline for millions. It provides vital nutrition, supports livelihoods, and drives economies, particularly in small island developing states. However, overfishing threatens its survival. World Tuna Day raises awareness of the need for sustainable fishing practices to protect tuna populations and preserve marine biodiversity.
A Brief History
World Tuna Day was officially established by the United Nations in 2016, following initial discussions by the Western and Central Pacific Fisheries Commission in 2011. The day reflects a global commitment to conserving tuna stocks and ensuring their long-term sustainability.
