Although Overfishing disrupts a vast number of different species and marine habitats, in particular tuna populations have severely declined due to overfishing and illegal overfishing. Although tuna does provide food and livelihoods for many people, they are more than just seafood. Tuna are a top predator in the marine food chain, maintaining a balance in the ocean environment.
Here’s why Tuna populations are most endangered due to overfishing:
Tuna are among the most commercially valuable fish on the planet. The Atlantic bluefin is a highly sought-after delicacy for sushi and sashimi in Asia—a single fish has sold for over $700,000! Driven by such high prices, fishermen use even more refined techniques to catch tuna. And the fish are disappearing as a result.
- Southern BlueFish TunaBeing one of Sydney’s most popular fish to eat, the Australian southern bluefin tuna industry is worth over $122 million annually. (2014 figure) Classified as ‘critically endangered’ on the IUCN’s Red List of threatened species means that population levels are down to around 5% of original levels, yet overfishing continues.
- Bigeye TunaBigeye tuna are an important commercial fish, especially prized in Asia, they are usually marketed as fresh or frozen.As bluefin tuna populations shrink around the world, pressure on bigeye fisheries is increasing. They are also classified as ‘vulnerable’ and overfishing continues in the Eastern and Western Pacific Oceans.
- Yellowfin TunaAccording to the ISSF Scientific Advisory Committee, Yellowfin are overfishing and are classified as ‘nearly threatened.’ They are also increasingly susceptible to by-catch as juvenile yellowfin school with adult skipjack. They are an important commercial tuna species, particularly for the raw sashimi market.
- Albacore Tuna
This species are smaller and extremely commercially important, as they are one of the two main canned tuna species (along with skipjack), and labeled as ‘solid white’ tuna. They are mainly overfished in the Northern and Southern Atlantic Oceans.
Greenpeace have a canned tuna guide that you can refer to when purchasing Tuna.
