A new report on the value of global tuna fisheries has found that despite an increase in catch each year, the end value of the fish has decreased.
The Pew Charitable Trusts' report called "Netting Billions 2020: A Global Tuna Valuation," is not the first to warn of the threat that over-fishing tuna stocks poses.
But it explains that as well as threatening marine ecosystems, ever-growing tuna fishing is inefficient and costly for industries and communities that depend on them.
This is especially significant in the Pacific which is home to the world's largest tuna fishery.
Pew's Director of International Fisheries, Amanda Nickson, spoke about the report's findings to Moera Tuilaepa-Taylor.
