March 9, 2021 — Marcel Kroese is WWF’s global tuna lead and has been involved in marine conservation as a researcher and professional since 1992, with working experience in East and West Africa, the Pacific, and Central America.
Picture a tuna. No, not a can. A fish. It is sleek and strong. Its scales flash as it dives like a torpedo to depths of 1,000 meters. If it were a car, James Bond would drive it. If it were a cat, it would be a cheetah. Yet these spectacular, athletic sea creatures are not afforded the same awe and wonder by humans as the big cats. We value tuna as a luxury food or a more humble “shelf-stable protein,” which is handy when stocking up for a pandemic. Either way, they are just food.
Certainly, tuna have fed countless generations throughout human history. From the palm-fringed islands of the Pacific to the diverse nations of the Mediterranean, tuna have been part of the diet and part of the culture. But before they make it to the plate, they played a vital role in the functioning of the ocean ecosystem – because fish don’t just inhabit the ocean. They fuel it.
