A 440-pound Pacific bluefin tuna sold for $117,000, which equals about $265 per pound. The new owner of this overpriced fish is Kiyoshi Kimura, who runs a popular chain of sushi restaurants and has been known to splurge at the first auction of the new year.

Kimura bought a similar sized tuna in 2013 for 15 times what he paid this year — $1.8 million for a 490-pound fishAccording to The Washington Post, Kimura "got into a vicious bidding war with the owner of [a] rival sushi chain."

But the popularity of bluefin tuna has left the species on the brink of extinction. According to a conservation organization, the number of Pacific bluefin tuna has dropped nearly 96 percent, and rising auction prices aren't helping.

Environmentalists are calling for Japan, the largest consumer of bluefin tuna in the world, to implement science-based catch limits on both sides of the Pacific Ocean.
