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.
A 257-ton increase is made to Japan’s Atlantic bluefin tuna quota for 2022.
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.
How much bluefin tuna is still available?
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.”
How much bluefin tuna is still present in the world?
One of the most valuable fish in the world, the Pacific bluefin tuna is still severely overfished, according to the most recent stock assessment.
A fresh stock assessment, which reveals the population is only 3.3% of its unfished level, was published this week by the experts that monitor the health of Pacific bluefin tuna, one of the most recognizable and expensive fish species in the world. This demonstrates the continuous need for more efficient management of the fishery and verifies the species’ severely reduced status.
Despite the assessment’s finding that the population has marginally increased over the previous two years from a low of 2.6% of its unfished size, the precarious situation the species is in as a result of years of overfishing, which continues today, cannot be hidden.
According to the evaluation by the International Scientific Committee for Tuna and Tuna-Like Species in the North Pacific Ocean, juvenile fish, or fish too young to reproduce, made up the majority of the most recent catch. Fish populations are not likely to thrive if they are removed from the water before they can breed.
Furthermore, despite the stock’s severe depletion, the global catch increased between 2015 and 2016 as four of the world’s top five fishing nations exceeded their quotas.
Despite being more than twice as many as in 2015, the report notes that the number of Pacific bluefin spawned in 2016 was just marginally above the average over the previous 50 years. Even more concerning, the forecasts of present and future growth are primarily based on this one data item. Because the numbers have not been validated by other sources and are therefore highly questionable, basing management choices on a single estimate is extremely dangerous.
What should you remember most about this evaluation? Pacific bluefin needs to be rebuilt, but considerable work remains. The Inter-American Tropical Tuna Commission (IATTC) and the Western and Central Pacific Fisheries Commission jointly monitor the species due to its migrations across the Pacific Ocean from Japan to the United States and Mexico (WCPFC). Even while the species is still in the early stages of rebuilding, those organizations shouldn’t exploit this slight rise in abundance as an excuse to boost fishing, presuming the assessment is accurate. To confirm that the population is in fact on the road to recovery, IATTC and WCPFC managers must adopt a science-based approach and settle on a Pacific-wide harvest strategy that includes precautionary aims and previously agreed-upon criteria for regulating the fishery.
The leading fishing nations for this species—Japan, Mexico, South Korea, Taiwan, Province of China, and the United States—must demonstrate that they take the rebuilding effort seriously and take steps to make sure that their fishermen do not continue to exceed catch limits. This goes along with stricter, proactive approaches to Pacific bluefin management at the WCPFC and IATTC. Quota overages jeopardize the success of any rebuilding strategy and the species’ long-term survival.
The evaluation calculates that the abundance of Pacific bluefin has increased by less than 1%, which is well within the study’s margin of error. The species is still badly overfished by any standard, and any rash or unwarranted rise in catch will reverse recent progress.
Prioritizing compliance and fulfilling their promise to the Pacific bluefin’s recovery in the interim, fisheries managers should wait for additional assessments before raising catch limits.
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.
Do bluefin tuna populations grow over time?
The International Seafood Sustainability Foundation (ISSF) reports that numerous tuna stocks are currently overfished, which means that adult fish are being grabbed more quickly than they can reproduce and repopulate the population. The Atlantic bigeye and the Indian Ocean yellowfin tuna are being overfished with recent increases in catch levels, while the Pacific bluefin tuna is severely overfished. Even though the skipjack tuna is fairly hardy, if overfishing is not adequately controlled, it might quickly become vulnerable.
Bigeye tuna is favored for sashimi in Asia and is available fresh and frozen in other countries. Pressure on bigeye fisheries is rising as bluefin tuna populations decline globally. Overfishing and illegal fishing have significantly reduced bluefin tuna stocks over the past few decades, affecting not only Pacific bluefin tuna but also Atlantic and Southern bluefin tuna. The demand for this fish in high-end sushi markets has been a major factor in population decreases, and their fates are uncertain.
Can you catch any bluefin tuna?
The daily retention cap for large, medium, or gigantic bluefin tuna is currently three fish per vessel, each day (measuring 73″ or greater).

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 deadliest of the lot, 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.
