Golden Bigeye Tuna is apparently so rare that Sushi Taro chef/owner Nobu Yamazaki had never even heard of it.

But today, he’ll receive the fish—a 138-pound tuna line-caught off the coast of the Philippines—from distributor Samuels and Son Seafood. In a press release in honor of the lone fish, the distributor called it “one of the world’s most sought after tuna” and a “one in a million find.” This is the first time they’ve ever imported one.

“The last time a fish like this was caught was about five years ago,” says Samuels and Son Seafood VP Joseph Lasprogata in the release.  “Normally creatures which stand out in the ocean are eaten by predator early on. So to see a mature individual with such primitive color variation is highly unusual.”

Among the features of the Golden Bigeye Tuna are golden colored skin and red meat. While most bigeye tuna have black eyes, this one had white eyes (although they’ve darkened out of water now that the fish is dead). Yamazaki tells Y&H he’ll probably serve it as a sushi and sashimi special. “We’ll have to cut it and taste it,” he says. “I just don’t know what to expect.”

He says he’ll probably charge the same as other tuna on the menu, depending on the quality of the meat.  “If it’s just a rare tuna but it’s the same as the regular tuna, then we’re not going to charge anymore than we should,” he says.

But if you want to try it, you should probably head to Sushi Taro sooner rather than later. Depending on the popularity of the rare tuna, Yamazaki says the fish will likely be finished off by the end of the week.
