A Single Specimen of Fish Was Auctioned for an Impressive US$ 3.1 Million, Becoming the Most Expensive in the World. Discover Why This Fish Is Worth So Much!
The bluefin tuna, internationally known as bluefin (Thunnus thynnus), is widely recognized as the most expensive fish in the world. This title is due not only to its exceptional quality meat but also to its rarity and the prestige associated with its consumption, especially in Japanese cuisine.
The bluefin tuna is the largest among tuna species, capable of reaching up to 3 meters in length and weighing over 600 kg.
Its meat is highly valued for its tender texture and high fat content, features that provide a rich flavor and a buttery mouthfeel. These qualities make bluefin especially desired for sushi and sashimi dishes.

A large part of the Netherlands lies below sea level and remains dry only because an invisible machine of dikes, pumps, and giant gates works nonstop, a system born from the tragedy of 1953, when the North Sea invaded the country and killed 1,836 people.

Weighing as much as nine nuclear aircraft carriers, the Pioneering Spirit is the largest ship ever built and was made for a single task that no other machine in the world can accomplish: removing entire oil platforms from the seabed of the North Sea in one go.
Record Prices
In 2019, a bluefin tuna weighing 278 kg was auctioned at the Tokyo fish market for an impressive US$ 3.1 million (around 11 thousand dollars per kilogram), setting a world record.
More recently, in January 2025, another bluefin tuna weighing 275.7 kg was sold for US$ 1.3 million at the traditional Toyosu Market auction, also in Tokyo. These events highlight the exorbitant value that this fish can reach in specialized markets.
Availability and Consumption in Brazil
In Brazil, the consumption of bluefin tuna is limited due to its high cost and the need for importation. Restaurants specializing in Japanese cuisine often join forces to acquire the fish, sharing the import costs.
The purchase price varies between R$ 500 and R$ 800 per kilogram, depending on the cut. For the end consumer, a pair of sushi with bluefin tuna can cost up to R$ 160.
Overfishing of bluefin tuna has led to significant concerns about the sustainability of the species.
In 2017, Japan and other fishing countries agreed to impose strict quotas on bluefin tuna fishing, after overfishing had reduced its population to less than 3% of historical levels. Thanks to conservation measures and the implementation of fishing quotas, bluefin tuna populations have shown signs of recovery.
In 2022, the International Seafood Sustainability Foundation reported that the bluefin tuna population had recovered to nearly 25% of its unfished levels, exceeding the 20% target set for 2034.
