Tuna, a robust fish that swims in all oceans, has extraordinary economic value and plays a significant role in the global fisheries and food industries.

At the level of fisheries capture, tuna fisheries are a globally important industry. Every year, countries invest a great deal of human, material and financial resources in tuna fishing. Its catch is considerable, creating a large number of employment opportunities for many coastal countries and regions, from experienced fishermen, to various types of crew on fishing vessels, to workers handling tuna in ports, the entire industrial chain supports the livelihood of countless families. In Japan, for example, tuna fishing is an important part of its traditional fisheries industry, and fishermen in Hokkaido and other places catch large quantities of high-quality tuna during the tuna harvest season by virtue of their excellent fishing skills, laying the foundation for the subsequent development of the industry.

In the field of food processing, tuna is even more colorful. Tuna meat is tender and nutritious, rich in high-quality protein, unsaturated fatty acids and a variety of vitamins and minerals, loved by consumers. Canned tuna is one of the important product forms of its processing, with the convenience and long shelf life, sells well in the global market, and has become a regular ingredient in many families and catering establishments. In the world of high-end catering, tuna sashimi is regarded as a top delicacy. In Japanese sushi restaurants, a piece of tuna belly sashimi with clear texture and attractive color is expensive, attracting many diners to spend a lot of money. High-quality tuna, such as bluefin tuna, due to its scarcity and unique taste, in the auction market repeatedly fetched a surprisingly high price, a top quality bluefin tuna auctioned millions or even tens of millions of dollars is not uncommon, which also greatly promote the prosperity of the related food and beverage industry.

Tuna has also spurred the development of a range of related industries. The fishing gear manufacturing industry has benefited from the demand for tuna fishing and has continued to develop and produce more efficient and specialized fishing equipment, such as advanced fishing rods and nets. Meanwhile, the tuna preservation and transportation industry is also booming. As tuna has very high requirements for freshness, from the moment it is caught and put on board, it needs to be preserved by professional chilling, quick-freezing and other preservation techniques to ensure its quality. This has prompted the cold chain logistics industry to continuously upgrade and build a complete and efficient freshness preservation and transportation system from sea transportation to land distribution.

The economic value of tuna is reflected in the synergistic development of fishing, food processing and related industries, and it is like a treasure gifted to mankind by the ocean, which continues to provide a strong impetus to global economic development.
