This fish has a good reputation because it gives a very high price at the auction. For example, in 2019, CNN reported that Kiyoshi Kimura, a self-proclaimed Japanese “Tuna King,” paid $ 3.1 million or 25 billion to break the record of 276 kilograms of bluefin tuna. The price is quite fantastic not for a tuna. Now what we need to know is that the Tuna is a different species from the Bluefin Tuna, the species cannot be too big and also the Tuna growth is very fast so the fish is easier to get in the sea.
While bluefin tuna is the only tuna that can grow large, for its own growth to the size of hundreds of kilograms takes quite a long time. Then the price sold by the fishermen was very expensive.
The actual price is relatively dependent on the weight of the tuna but adult bluefin tuna can reach 204 kilograms.
In Indonesia alone, many tuna fish are encountered in the waters of southern Java to the east. Tuna migration is in Indonesia from the south of the island of Java to East Nusa Tenggara.
What makes bluefin tuna so popular, and so valuable? We all know that preparing sushi and sashimi is a high art form in Japan, so there must be a complicated and quality reason for the supremacy of bluefin tuna, right?
Limited supply and export costs drive up prices
One factor that makes bluefin tuna so expensive is the law of supply and demand. Japan as the biggest consumer of bluefin has faced international criticism because of the capture of bluefin.
Experts say the demand for Pacific bluefin has caused overfishing, causing fish stocks to drop to only 2.6 percent of their historical numbers.
Conservation groups blame demand from the sushi and sashimi industry for a rapid population decline. Japan consumes 80 percent of the world’s bluefin tuna. Along with countries including Mexico, Korea and the United States, they have exceeded fishing quotas in recent years.
The International Union for Conservation and Nature has listed Pacific bluefin tuna as “vulnerable,” which means that a species is likely to be endangered unless circumstances threaten changes in its survival.
Atlantic bluefin tuna, a close relative of the Pacific bluefin, are listed as endangered animals. Recovery efforts for bluefin tuna populations have been made but the number of fish populations is still declining. Another relative, the southern blue fin, is also endangered.
The two groups responsible for managing Pacific bluefin tuna agreed in 2017 to work to restore fish populations by up to 20 percent by 2034. If the West and Central Pacific Fisheries Commission and the Inter-American Tropical Tuna Commission succeed in their objectives, then the bluefin tuna population projected to increase seven times the current level.
