Migrates across Oceans
Bluefin are the largest tuna and can live up to 40 years. They migrate across oceans and can dive more than 4,000 feet. Bluefin tuna are made for speed: built like torpedoes, have retractable fins and their eyes are set flush to their body. They are tremendous predators from the moment they hatch, seeking out schools of fish like herring, mackerel and even eels. They hunt by sight and have the sharpest vision of any bony fish. There are three species of bluefin: Atlantic (the largest and most endangered), Pacific, and Southern. Most catches of the Atlantic bluefin tuna are taken from the Mediterranean Sea, which is the most important bluefin tuna fishery in the world.
A new WWF report finds more than 85% of global fish stocks in our oceans are at significant risk of illegal, unreported and unregulated (IUU) fishing. Species affected by illegal fishing varies across the globe – from Bluefin tuna to mackerels, from snow crabs to shrimp, and hundreds of other species.
The Atlantic bluefin is a highly sought-after delicacy for sushi and sashimi in Asia—a single fish has sold for over $1.75 million! Driven by such high prices, fishermen use even more refined techniques to catch tuna. And the fish are disappearing as a result. Although tuna do provide food and livelihoods for people, they are more than just seafood. Tuna are a top predator in the marine food chain, maintaining a balance in the ocean environment.
