Boston on the Pacific: Ahi and Yellowfin Tuna

Updated: Jan 29


Bluefin or Yellowfin?

There it is, second-mention in our very own name, Boston Sword & Tuna, where you can buy fresh tuna fish online. And, coincidentally, tuna ranks second on the list of the most-consumed seafood in North America, trailing only shrimp for quantity and – arguably – popularity. As your best fresh seafood market online, we like to think of tuna ranking first, because it actually looks like a fish. A very big fish. Shrimp, delicious though they are, we see as kind of their own deal.

So, if tuna’s tops in fish, what’s the best kind of tuna? Well if you measure by quantity, then bluefin tuna is likely the leader. Bluefin is richer in oils at some times of year, and it has a higher fat content overall than yellowfin. Somebody drew a pretty good analogy with your choice of steaks: Bluefin tuna is like a finely-marbled Kansas City strip, or even prime rib, while yellowfin is like the tuna version of filet mignon. The structure of the meat, and the flavor, too, make this an unusually good comparison, even for your sea to home online fish market.

Then what about ahi? Well, at your own fresh seafood company, we can tell you that ahi is just what our Hawaiian friends and fisheries call tuna. Because of where it’s commonly caught, yellowfin is what people usually mean when they say ahi, although, in Hawaii, they call the related bigeye tuna “ahi,” too. For most of us, when we hear ahi, it means yellowfin, and because yellowfin is caught in tropical and subtropical waters, that’s what connected the ahi name to it even in North America.
