World Tuna Day 2022: Rich in Omega-3, minerals, proteins, and vitamin B12, Tuna has various other advantages. But the super fish is a victim of its own amazing qualities and nutritional properties, threatened as it is by the overwhelming demand from the human population.   


According to the United Nations, latest data shows that 33.3 per cent of the stocks among the seven principal tuna species are estimated to be fished at biologically unsustainable levels.


To underline the importance of its conservation so systems can be put in place to prevent tuna stocks from crashing, the UN General Assembly in December 2016 voted to officially observe a World Tuna Day. And the date for this was chosen to be May 2. 


World Tuna Day History And Significance


According to the UN, many countries heavily depend on tuna resources for their food security and nutrition, besides economic development, employment, government revenue, livelihoods, and even recreation.


The UNGA in its December 2016 resolution designated May 2 as World Tuna Day as it recognised the importance of “sustainably managed stocks in achieving the 2030 Agenda for Sustainable Development”, noting the “integrated and indivisible nature” of the agenda.


The resolution noted that the oceans have thousands of tuna fishing vessels operating, and that tuna fishery capacity is still growing in the Indian and Pacific oceans.


Addressing the problem of overfishing and the resultant decline in tuna stocks, the UN Legal Counsel has emphasised that effective implementation of the international legal framework, as reflected in the UN Convention on the Law of the Sea (UNCLOS) is of critical importance.
