How Many Bluefin Tuna Are Left In The World?

This population is strong, according to Nickson. In other words, the population will probably increase if the fish are allowed to live and reproduce. She continues by pointing out how crucial it is that the rebuilding aim will still permit some fishing activity. That is essential to preserving the tuna fleet as stocks restock.

The announcement follows this week’s shutdown of the U.S. commercial Pacific bluefin fishery by the National Marine Fisheries Service for the remaining four months of the year due to fishermen exceeding the 425 metric tons quota for that year.

Last month, the US federal government rejected a plea to declare Pacific bluefin tuna as an endangered species, disappointing environmental groups.

There is a separate standard when reviewing for the preservation of endangered species, according to Chris Yates, assistant regional administrator for NOAA Fisheries West Coast Region. According to him, “We need to establish that the species is likely to go extinct or is likely to become endangered of going extinct in the near future.”

There are currently 145,000 reproducing adults among the 1.6 million Pacific bluefin tuna in the ocean. So even though there are a lot fewer bluefin tuna than is ideal, Yates explains, “there are still a lot of them out there.”

Facts

The biggest tunas are bluefin, which have a lifespan of up to 40 years. They can dive more than 3,000 feet and move throughout all oceans. Bluefin tuna are shaped like torpedoes, have retractable fins, and their eyes are level with their bodies. They are designed for speed. From the minute they hatch, they are fierce predators, going after schools of fish like herring, mackerel, and even eels. They are the only bony fish with the best visual acuity for sight hunting. The largest and most endangered of the three bluefin species is the Atlantic, followed by the Pacific and the Southern. The most significant bluefin tuna fishery in the world, the Mediterranean Sea, produces the majority of the Atlantic bluefin tuna catches.

Tuna from the Pacific

As was already mentioned, only 2.6% of the 1950 stock size of Pacific bluefin tuna is still present today.

Here, scientists have really produced reliable figures that fairly depict the quantity of bluefin tuna still existing in the Pacific.

There were 1.6 million bluefin tuna left in the Pacific in 2017. 145.000 of these were reportedly reproducing adults.

In other words, the Pacific bluefin is the species of tuna that is most in danger of going extinct and should be evaluated accordingly.

The recovery of the tuna species from the verge of extinction is good news for the ocean.

The Atlantic and Southern bluefin tuna, which you are accustomed to seeing in supermarkets, has good news. These three species, along with two others, are beginning to rebound from overfishing.

Commercial fishing firms have been hunting them for decades, but there is now hope that they may not become extinct as was formerly feared.

The International Union for Conservation of Nature (IUCN), which recently updated its Red List, provided the news.

This list illustrates the global extinction risk of thousands of species. Although more than 38,000 species currently face the threat of extinction, some showed hints of improvement.

The majority of tuna species were regarded as being in grave danger of going extinct in 2011. These fish are among the most valuable in the world in terms of commerce, with 6 million tonnes estimated to have been captured in 2019.

Four of the seven regularly fished tuna species had encouraging news when their status was reevaluated in this update.

The Southern bluefin became Endangered rather than Critically Endangered, and the Atlantic bluefin went from Endangered to Least Concern. From being Near Threatened to Least Concern, albacore and yellowfin tunas also underwent this change.

According to Dr. Bruce B. Collette, chair of the IUCN SSC Tuna and Billfish Specialist Group, “These Red List evaluations provide evidence that sustainable fisheries practices work, with huge long-term benefits for livelihoods and biodiversity.”

We must keep up the enforcement of sustainable fishing quotas and strict sanctions against unlawful fishing.

The home of bluefin tuna.

The majority of the bluefin tuna’s life is spent in the open ocean, and they may be found in most of the world’s oceans. In the Atlantic, Pacific, and Southern oceans, there are different stocks that don’t mix.

The East Atlantic bluefin stock is what we observe off the British coast. They breed in the Mediterranean Sea and migrate through the Atlantic Ocean southward to West Africa and northward to the UK and Norway. They are not inhabitants, but rather frequent guests.

The West Atlantic bluefin stock migrates from Ecuador to Norway by way of the North Atlantic after spawning in the Gulf of Mexico. Similar to salmon, Atlantic bluefin are devoted to their breeding grounds and frequently visit them to lay their eggs.

The northern Pacific waters, particularly between the shores of Japan and China and the western coast of North America, are home to Pacific bluefin tuna. This stock of bluefin tuna typically prefers temperate waters, and they spawn in the Sea of Japan and the northwestern Philippine Sea. In contrast to the Atlantic, all tuna in the Pacific are from the same stock.

Typically, Southern Hemisphere waters, from the tropics to the sub-Antarctic, are home to southern bluefin tuna. They undertake yearly spawning journeys to the southeast of Java. They primarily inhabit the southern and eastern Indian Oceans as well as the southwest Pacific.

Why Is Bluefin Tuna Endangered?

The exquisite flavor and suppleness of bluefin tuna make it one of the most expensive fish in the world. Commercial fisheries pursue bluefin tuna all throughout the world, but they are in danger of being extinct.

  • Unknown, but probably in the hundreds of thousands, the estimated number of remaining animals in the wild.

Due to overfishing, the tuna’s population has decreased by 90% since the 1950s, making it an endangered species.

There are currently only a few thousand surviving in the globe after the first commercial catch was made in 1908. The bluefin tuna has a maximum length of 10 feet and a maximum weight of 1,500 pounds.

Due to the high demand from sushi restaurants around the world, who prize this species for its light red meat to consume that stays moist when cooked or frozen, the Bluefin population has been severely depleted.

One of the priciest seafood in the world, bluefin tuna sashimi may cost as much as $24 per piece in Tokyo.

The Bluefin is especially well-liked by sushi enthusiasts because it is exceptionally delicate and fatty. Avoiding Bluefin tuna products would be a simple method to prevent the extinction of this species of fish.

In 2021, how many bluefin tuna are there still in the world?

Where can you find bluefin? The Atlantic, Pacific, and Indian oceans are all home to bluefin. How many bluefin tunas are still present on Earth? More over a million Bluefin Tunas exist.

How much bluefin tuna is there still in existence?

On the east coast, a local bluefin will cost between $20 and $40 a pound. For bluefin from Japan, you might have to fork over more than $200 per pound.

In 2022, how many bluefin tuna are there still in the world?

According to an intergovernmental fishery organization’s resolution, Japan’s 2022 Atlantic bluefin tuna quota would rise by 257 tons from the previous year to a total of 3,483 tons, the nation’s Fisheries Agency announced on Wednesday.

Assuming that all tuna stocks are recovering, the International Commission for the Conservation of Atlantic Tunas resolved during a recent online meeting to increase the overall catch limit for nations like Japan.

Will bluefin tuna reappear?

The fishery for bluefin tuna in the General category will end at 11:30 p.m. on August 4, 2021. On September 1, 2021, the fishery will reopen with a daily retention restriction of one fish per vessel.

Bluefin tuna: Can it be saved?

For more than ten years, WWF has worked to save Atlantic bluefin tuna in the Mediterranean. Our goal is to halt overfishing and ensure the Eastern Atlantic and Mediterranean stock recovers. The International Commission for the Conservation of Atlantic Tunas (ICCAT), the organization that oversees fisheries, has relied heavily on WWF for most of its judgments.

Will there be no more bluefin tuna?

Ocean-dwelling bluefin tuna can reach lengths of up to 10 feet and weights of 1,200 pounds. Bluefin tuna are warm-blooded and have the ability to control their body temperature, which aids them during their arduous trips across the Atlantic. Top ocean predators, bluefin tuna occasionally engage in cooperative hunting similar to wolves. Bluefin tuna can sprint through the water at up to 50 mph and can cover oceans in just a few weeks thanks to their streamlined bodies and retractable fins.

Due to years of overfishing, bluefin are prized as a high-end dish at sushi restaurants and are in danger of being extinct. On its “Red List” of vulnerable species, the International Union for Conservation of Nature categorizes the Atlantic and Southern bluefin as either critically endangered or endangered. The National Marine Fisheries Service reports that although the Pacific bluefin tuna is now being overfished. Regrettably, bluefin still appears on certain menus. A single tuna sold for $177,000 in a fish market in 2010 due to high tuna prices maintained by the sushi industry, which also promotes illicit and unreported fishing.

When BP’s oil leak in the Gulf of Mexico contaminated important spawning grounds in spring 2010, the situation for Atlantic bluefin was significantly worsened. According to scientists, the leak destroyed 20% of the juvenile tuna in the region. Since 1970, the bluefin stock in the western Atlantic has decreased by more than 80%. Between 1957 and 2007, the stock of fish in the eastern Atlantic shrank by 74%.

1. Legal protections are desperately needed for this species. The Atlantic bluefin is a species that has been requested for protection under the Endangered Species Act by the Center for Biological Diversity. The decision on that petition is now pending.

2. As a result of international authorities’ rejection of fishing quotas to safeguard bluefin, it is now up to consumers to reduce demand. The Center has started a bluefin boycott, asking customers to promise to stay away from the fish and eateries that offer it. Restaurants and chefs are also invited to sign a pledge promising not to purchase or serve this endangered species.

Bluefin tuna can be saved. Sign the Center’s boycott pledge right away, share it with your loved ones, post it on Facebook and other social media platforms, and let your neighborhood sushi joints know about this initiative. We can reduce fishing and conserve thousands of bluefin by reducing the market demand for this species.

Declare your support for the Endangered Species Act’s protection of bluefin tuna. Inform your congressional representative and the Fisheries Service that bluefin need immediate protection. You should also write a letter to the editor of your local newspaper.

Who or what consumes bluefin tuna?

Even though the canned goods section of the grocery store may be where most Americans have first encountered a school of tuna, the species is one of the most intriguing fish found in the oceans.

The largest and baddest of the bunch, the Atlantic bluefin tuna, can weigh up to 1,400 pounds and bulks up by consuming small fish like sardines, herring, and mackerel as well as gourmet foods like crab, lobster, and squid.

The bluefin tuna inhabits some of the world’s most arctic waters in the Atlantic and Mediterranean Seas. Conservationists fear that the BP oil spill may have affected these fish because they breed in the Gulf of Mexico from April to May.

Bluefin tuna have just a few natural predators, such as killer whales, sharks, and a small number of other large fish, and are able to live up to 20 years in the wild. However, a startling 74% of eastern Atlantic and Mediterranean bluefins have vanished over the previous 50 years. Overfishing, according to scientists, is to blame.

In Japanese sushi restaurants, a tiny piece of bluefin can cost up to $20 when it is served raw. In 2009, a 440-pound bluefin caught a market record offer of $220,000.

Earlier this year, international efforts to outlaw the commercial trade in Atlantic bluefin tuna failed. Therefore, the critically endangered delicacy’s darkest days are yet ahead unless it is taken off the menu soon.
