Is Tuna Expensive?

The price of Tuna can vary depending on several factors, including the type of Tuna, the cut, the location, and the season. Generally, Bluefin Tuna is considered the most expensive type of Tuna, especially if it is caught and sold fresh. This is due to the high demand, particularly in sushi and sashimi dishes.

In addition, specific cuts of Tuna, such as the fatty belly section known as toro, can be expensive due to their unique flavor and texture. As a result, fresh Tuna is generally more expensive than canned Tuna, and the price may also vary depending on the country of origin and the level of sustainability.

The world’s most expensive Tuna

The most expensive Tuna ever sold was a bluefin Tuna caught off Japan’s coast in 2019. The Tuna weighed 278 kilograms (612 pounds). They were sold at the famous Tsukiji fish market in Tokyo for a record-breaking 333.6 million yen, approximately $3.1 million. The buyer of the Tuna was a Japanese sushi chain owner who paid a high price to secure the most elevated quality Tuna for his restaurants. This price set a new world record for the highest price ever paid for a single fish, surpassing the previous record of $1.8 million, which was also for a Bluefin Tuna sold at the Tsukiji fish market in 2013.

The Different Cuts Of Tuna

Tuna can be cut into several different types of cuts, depending on the part of the fish and the intended use. Here are some common cuts of Tuna:

  1. Tuna steaks: Tuna steaks are thick slices of Tuna that are typically cut from the loin. They are popular for grilling, pan-searing, or roasting and can be served with various sauces and seasonings.
  2. Tuna loin: The Tuna loin is the large, cylindrical portion of the fish that runs along the backbone. It is typically the highest quality and most expensive part of the fish. It is often used for sashimi or sushi.
  3. Tuna belly: The Tuna belly is the fatty, flavorful portion of the fish located beneath the skin along the belly. It is highly prized for its rich flavor and is often used in sushi and sashimi.
  4. Tuna tail: The Tuna tail is the portion of the fish that includes the tail fin and adjacent meat. It is typically less expensive than other cuts. It is often used for making canned Tuna or ground Tuna burgers.
  5. Tuna cubes: Tuna cubes are small, bite-sized pieces of Tuna that are typically used for making poke bowls or other dishes that call for diced Tuna.

By understanding the different cuts of Tuna, you can choose the best cut for your intended use and ensure that you’re getting the most out of this delicious fish.

What Is The Most Expensive Tuna Cut?

The most expensive cut of Tuna is the fatty and flavorful belly section, known as “toro” in Japanese. Specifically, the most costly part of the toro is the o-toro, which comes from the fatty part of the Tuna belly closest to the head. This is because it is the most tender and has the highest fat content, which gives it a rich, buttery flavor and a melt-in-your-mouth texture.

In high-end sushi restaurants, o-toro can be extremely expensive, ranging from several hundred to thousands of dollars per pound, depending on the quality and availability. However, it’s important to note that o-toro is a luxury item and should be consumed in moderation as part of a balanced diet.

Cheap Cans vs. Expensive Fresh Tuna

Here are several factors that contribute to the difference in price between canned Tuna and fresh Tuna:

  1. Processing: Canned Tuna is typically processed and canned soon after it is caught, which allows it to be stored and transported easily. This reduces the cost of handling and shipping, lowering consumers’ prices. On the other hand, fresh Tuna needs to be transported quickly and carefully to ensure it stays fresh, which can be costly.
  2. Availability: Canned Tuna is available year-round and is often made from less expensive species of Tuna, such as Skipjack or Albacore. Fresh Tuna, especially high-quality species like Bluefin or Yellowfin, can be more challenging to source and may only be available during certain seasons or in specific locations.
  3. Quality: Fresh Tuna is generally considered higher quality than canned Tuna, as it is fresher and has a better texture and flavor. This higher quality is reflected in the price.
  4. Market demand: There is a high demand for canned Tuna due to its convenience and affordability, which drives the price down. Fresh Tuna, especially high-quality species, is in greater demand by high-end restaurants and sushi bars, which can cause the price to go up.

Overall, the lower cost of processing and shipping and the use of less expensive species of Tuna make canned Tuna a more affordable option than fresh Tuna. However, it’s important to note that fresh Tuna is generally considered to be of higher quality and is prized for its flavor and texture.
