World Tuna Day

World Tuna Day History

World Tuna Day seeks to raise awareness about the importance of tuna to the world's oceans, as well as to the people and communities that depend on it for food and livelihoods. This day also highlights the need for sustainable management practices to ensure the long-term health of tuna populations and the ocean ecosystem.

The history of World Tuna Day in Canada dates back to 2016, when the United Nations General Assembly declared May 2 as World Tuna Day. This decision was made to recognize the important role that tuna plays in global food security and as a source of income for many coastal communities. Canada has since joined other international community members in observing this day as a way of demonstrating support for sustainable tuna fishing, scientific research, and responsible management of tuna stocks.

Canada has a significant role to play in the global tuna market, with Atlantic bluefin tuna being a highly valuable species that is subject to both commercial and recreational fishing in Canadian waters. As such, it is important for Canada to participate in efforts to ensure sustainable tuna fishing practices, in order to conserve tuna populations for future generations. World Tuna Day in Canada serves as a reminder of this crucial need for responsible management and conservation efforts.

Top 7 Facts for 2026 World Tuna Day in Canada

• Canada’s historical connection to the species remains a major point of interest, as the largest Atlantic bluefin tuna ever recorded—a massive 1,496-pound specimen—was caught off the coast of Aulds Cove, Nova Scotia, in 1979 by the legendary angler Ken Fraser.
• Recent scientific findings published in the journal Fish and Fisheries titled Navigating Future Waters: The Resilience of the Atlantic Bluefin Tuna Under Climate Change suggest that warming ocean temperatures will cause these iconic fish to shift their feeding grounds progressively further north into Canadian waters over the coming years.
• According to the first-ever MSC Canada Tuna Report, Canada has become a global leader in sustainable seafood, now ranking fifth in the world for the volume of Marine Stewardship Council certified tuna sold, following a staggering 582% increase in consumer demand since 2021.
• For health-conscious shoppers, Pacific albacore tuna harvested in British Columbia is frequently highlighted by the Ocean Wise seafood program because these fish are typically younger and smaller than tropical varieties, resulting in significantly lower mercury accumulation.
• The International Commission for the Conservation of Atlantic Tunas recently approved a 13% increase in the total allowable catch for western Atlantic bluefin tuna for the 2026 through 2028 seasons, reflecting a positive trend in population recovery that directly affects the quotas for Atlantic Canadian harvesters.
• There is ongoing debate regarding the legal protections for these fish, as the Committee on the Status of Endangered Wildlife in Canada has previously recommended an endangered listing, yet the federal government continues to manage the species under the Fisheries Act rather than the Species at Risk Act to balance conservation with the socio-economic needs of coastal communities.
• This year's global observance follows the international theme Sustaining Tuna, Sustaining Nations, which emphasizes the critical role that migratory fish stocks play in the economic stability and food security of both coastal and inland regions.
