From the Trader Joe's Catalogue:
Yellowfin Tuna in Oil (aka, Can of Tuna fish)
About 99% of tuna eaten comes from a can. It's a pantry staple icon. And there are a lot of options in the market, so why choose Trader Joe's Yellowfin Tuna in Oil? There are a plethora of reasons, but here are a few pointed ones. We work closely with a prominent, sustainable-focused fishery to procure our Yellowfin tuna. Recognized for their yellow-tipped fins, large size (they can reach up to 400 lbs and 90 inches, fully grown), and fast swimming speeds, their flesh is tender, light and pale pink. We pack our tuna in olive oil with a touch of salt (that's it!) to preserve its delicate, meaty flavor and firm, flaky texture. It's a premium catch for a pocket-friendly price -- $1.99 for a five ounce can. That's why.
