How Many Bigeye Tuna Are Left?

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 is taking place in both the Eastern and Western Pacific Oceans, according to data gathered by the Scientific Advisory Committee of the International Seafood Sustainability Foundation (ISSF).

New Information Also Provides Catch Records for Skipjack

New evaluations of tuna populations in the western and central Pacific Ocean have been made by scientists, and the findings have various unsettling implications for the largest tuna fishing grounds in the world.

The Western and Central Pacific Fisheries Commission’s (WCPFC) Scientific Committee presented data in late July that put the entire 2013 tuna catch at above 2.6 million metric tons. In addition, several tuna species are losing their ability to breed, sometimes to dangerously low levels.

Less than 20% of the bigeye tuna population is still there, according to the most recent estimate of the species in the area.

This is an important breakthrough because, as scientist John Hampton, who is in charge of the team that carried out the assessments, was cited as saying by the Pacific News Center, “fishing nations have agreed that a population level this low “represents an intolerable risk” to the stock.” And while bigeye catch on longlines fell to its lowest level since 1996, catch on purse seines rose to its highest level.

In addition to luring young bigeye tuna, purse seine boats also use floating toys to attract and ultimately catch skipjack tuna with their huge nets. To minimize the catch of young bigeye, WCPFC member nations have agreed to a seasonal restriction of the FAD fishery. However, scientists have long warned that this approach will not restore the population to healthy levels.

According to Nickson, “the most recent science dispels any doubt as to the urgent need for fishing nations to limit levels of FAD fishing.” It is crucial that the nations that make up the Commission accept a plan for restocking bigeye tuna that is supported by research and has a good chance of being successful.

The Pacific bluefin tuna population was only 4% of its pre-fishing size in April, according to scientists, and the species’ survival is in jeopardy due to the unreasonably high juvenile capture.

Scientists claim that yellowfin and skipjack tuna populations in the western and central Pacific are at safe levels, but there is concern that catches shouldn’t be permitted to rise. The continued presence of huge vessels in the fishing is especially alarming.

In 2013, there were 297 purse seine vessels actively pursuing tropical tuna, according to a paper distributed during the Scientific Committee meeting in August. The overall fishing effort was likewise at its peak.

When the commission meets in December in Apia, Samoa, management decisions will be based on the report of the WCPFC Scientific Committee meeting.

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 great demand from sushi restaurants throughout the world, who prize this species for its light red meat to ingest that stays moist when cooked or frozen, the Bluefin population has been severely endangered.

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.

What are the threats to tuna?

The species has experienced a particularly spectacular collapse as a result of widespread overfishing, especially of bluefin tuna.

Even while there is more awareness of the dire situation facing bluefin tuna, there is still little prospect of a long-term recovery for this species, and there are worries that bigeye and yellowfin tuna will also meet a similar end.

  • Anchovies, herring, mackerel, flying fish, and other small schooling fish
  • Eels, squid, and crustaceans

Tuna is consumed by:

  • larger species of tuna
  • Billfish
  • Sharks
  • Humans
  • Avoid purchasing tuna since it is seriously threatened by overfishing. When making a purchase, make sure the product was sourced responsibly and look for the MSC seal of approval. For more details, consult the WWF’s sustainable seafood guide.

The bigeye tuna is extinct; why?

The major risks to both endangered bluefin tuna populations and the species related to them include things like bycatch (when tuna are mistakenly grabbed by fisherman), overfishing, and climate change.

Where may bigeye tuna be caught?

Their residence. Bigeye tuna can be found in the waters around southern California and the U.S. Pacific Islands as well as the Pacific, Atlantic, and Indian oceans.

Does bigeye tuna have a future?

Because it is legally caught in accordance with American standards and is sustainably managed, wild Atlantic bigeye tuna from the United States is a wise seafood choice.

In 2020, how many bluefin tuna are there still in the world?

This population is strong, according to Nickson. In other words, the population will probably increase provided the fish are allowed to live and breed. Additionally crucial, she adds, is that the rebuilding aim will still permit some fishing activity. That’s crucial to preserving the tuna fleet while stocks refill.

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.”

Do you prefer bigeye tuna to yellowfin tuna?

There are two different varieties of Ahi tuna species: yellowfin and bigeye. The word “ahi” is derived from the Hawaiian word for fire and refers to the smoke that is produced when a fish is ready to be caught as the fishing line crosses the boat swiftly. Although these fish are prized for their excellent flavor, they are also known as sport fish. They can be fished all year round, but they are typically caught in the summer. Cubed tuna that has been marinated and is typically used to make poke bowls is typically served over rice.

The dorsal, anal, and finlet fins make it simple to distinguish between a yellowfin tuna and a bigeye tuna. A yellowfin tuna will have it, hence the name. A bigeye has a plumper body, a larger head, and obvious-looking large eyes, whereas a yellowfin has a narrower body.

Additionally, there is a taste difference. Bigeye tuna is discovered to swim in cooler seas and has more fat than yellowfin, giving it a lovely buttery flavor and making it ideal for grilling because it won’t dry out as quickly. Both of the tunas taste wonderful in sashimi and sushi. Yellowfin is well recognized for being thinly sliced and used for sashimi. It is known for having a milder flavor and a firmer texture.

Ahi is regarded by experts as a particularly healthy fish that is very slender. Both bigeye and yellowfin tuna are low in salt and saturated fat. They also contain high levels of phosphorous, B6, and B12 vitamins. If you are seeking for a natural supply of omega-3 fatty acids and some magnesium, these two are fantastic selections as the healthful advantages to your heart.

Bigeye and bluefin tuna are they the same fish?

Bigeye tuna are typically smaller than bluefin and similar in size to yellowfin. They have long, streamlined bodies, top sides and backs that are a dark metallic blue, and lower sides and belly that are almost white. They have a 15-year life span. Bigeye are found throughout the subtropical and tropical regions of the Atlantic, Indian, and Pacific Oceans (though not in the Mediterranean).

What dishes call for bigeye tuna?

For sashimi, bigeye tuna are highly regarded. They have a deeper flavor than Yellowfin, a high fat content with marbling towards the skin, and a somewhat pronounced flavor. Like other tuna, it has a firm, “meaty” texture and big flakes. It tastes best when cooked rare to medium-rare or when presented as sushi. Tuna that has been overcooked is “dog chow,” harsh and flavorless like eating cardboard.

These are the tuna grades: The best fish is No. 1 “Sashimi-grade,” which is the freshest and contains the most fat. Next best is “Grill-grade” No. 2. The quality of Nos. 3 and 4 is inferior.

Which tuna was ever captured at its largest?

The largest bluefin tuna ever caught set a world record in 1979 in Nova Scotia, Canada. According to the International Game Fish Association, the fish was 1,496 pounds.

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. The sushi industry keeps prices for tuna high — a single tuna sold for $177,000 in a fish market in 2010 — and encourages illicit and undocumented 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 sorely 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. Consumers must now reduce demand since international regulators have failed to impose fishing quotas to conserve bluefin. 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.
