Saving Seafood

The Surprising Story of Swordfish You May Not Know

May 1, 2019 —  The following was published by NOAA Fisheries:

Today’s North Atlantic swordfish population is a great fishery rebuilding story.

Twenty years ago, this predatory fish was in trouble. Their population had dropped to 65 percent of the target level. This means there wasn’t enough North Atlantic swordfish in the water to maintain their population in the face of fishing by the many countries who share the resource.

Fast forward to 2009 and the international commission that manages species like swordfish declared the Northern Atlantic stock fully rebuilt. That announcement came a year ahead of the 2010 target date set in the International Commission for the Conservation of Atlantic Tuna’s (ICCAT) 10-year rebuilding plan.

“If it’s U.S.-harvested swordfish, consumers can feel confident it’s a smart seafood choice,” said Rick Pearson, NOAA Fisheries fishery management specialist. “We should reward our sustainable stewardship practices at the seafood counter.”

Rebuilding an Important Population

Efforts to restore a dwindling population of North Atlantic swordfish date back to 1985 when NOAA Fisheries implemented the first U.S. Atlantic Swordfish Fishery Management Plan. This plan reduced the harvest of small swordfish, set permitting and monitoring requirements, and launched scientific research on the swordfish stock. Minimum size limits and enforcement processes came shortly after when ICCAT issued its first recommendation on swordfish in 1990.

Despite these and other management strategies implemented over the next eight years, the stock continued to suffer. By the late 1990s, the average weight of swordfish caught in U.S. waters had fallen to 90 pounds, a drop from the 250-pound average fishermen enjoyed in the 1960s. This was in part because the population decline meant fishermen were catching younger fish.

What ultimately reversed their downward course was the broad suite of actions built up by the beginning of the 21st century.

“There is no one measure that could have brought this population back from the decline,” said Pearson. “Sustainable fishery management requires a comprehensive science-based approach that considers the biological needs of the fish population, the health of fisheries, the fishing industry, and coastal communities.”

In the United States today:

  • A limited number of vessels can target swordfish commercially with longline gear.

  • All fishermen must abide by minimum size limits, and many must also abide by retention limits.

  • Closures prevent pelagic longline fishing in waters with historically high levels of bycatch species, including undersized swordfish.

  • Satellite tracking systems are mandatory on some vessels that target swordfish.

  • The use of circle hooks is required in commercial fisheries to increase the survival of sea turtles and other animals caught accidentally.

  • Commercial fishermen must attend workshops where they learn to properly handle and release bycatch, including undersized swordfish.

  • Observer programs provide fishery scientists and managers with needed data.

Leading the International Community

Some of these measures can be traced back to the ICCAT rebuilding plan, but many are the result of U.S.-led efforts to protect swordfish, reduce bycatch of other species, and sustainably manage fisheries that interact with swordfish.

Pearson and others also point to the key role the U.S. commercial fishing industry played in helping to establish these domestic efforts and supporting greater international collaboration.

“The United States led the charge internationally to adopt measures to recover North Atlantic swordfish,” said Christopher Rogers, director of International Fisheries. “We pressed our international partners to adopt measures U.S. fishermen were already practicing, such as catch limits, minimum sizes, recording and reducing dead discards, and appropriate observer coverage. Strong U.S. leadership helped ensure the international community shared the burden for rebuilding this iconic species.”

Support for a Valuable U.S. Fishery

In the decade since ICCAT first declared that North Atlantic swordfish are not being overfished, the United States has seen a fall in its total annual catch. In 2017, U.S. fishermen caught just 14 percent of the total swordfish catch reported to ICCAT.

There are several reasons for this decline, says Pearson, including rising fuel prices, an aging commercial fleet, and competition from often lower-quality imported frozen products.

To help more U.S. fishermen take advantage of our national ICCAT-allotted quota, NOAA Fisheries has made several changes in the last decade to commercial and recreational restrictions, such as:

  • Removing vessel size and horsepower restrictions on pelagic longline permits.

  • Increasing retention limits on some permits.

  • Launching a hand gear permit, allowing fishermen to participate in the fishery without spending more to buy a longline permit from another vessel.

  • Making it easier for fishermen to get and renew permits.

But there is more work to be done to ensure our regulatory program is effective in both maintaining swordfish populations and supporting the fishing industry. We are currently examining whether some area-based and gear management measures that affect swordfish fisheries could be modified in light of the success of a program that has reduced bluefin tuna bycatch.

“The U.S. fishery management process is a dynamic process,” said Pearson. “Protecting the North Atlantic swordfish population from overfishing while ensuring fishing opportunities for our recreational and commercial fishermen requires the best available science and responsive management.”

Environmental group sues U.S. for material on endangered status for bluefin tuna

February 15, 2019 — The Center for Biological Diversity on Wednesday sued the U.S. government for not releasing public records on why it denied protections for Pacific bluefin tuna, a sushi delicacy, under the Endangered Species Act.

In 2016, CBD petitioned the National Marine Fisheries Service to list the Pacific bluefin tuna as threatened or endangered under the ESA and to designate critical habitat concurrently with its listing.

ISSF Report Shows Many Tuna Stocks Not Meeting Criteria for Marine Stewardship Council (MSC) Sustainability Standard

January 25, 2019 — The following was released by the International Seafood Sustainability Foundation:

Only five out of 19 major commercial tuna stocks are being managed to avoid overfishing and restore depleted fish populations — and have earned a passing score for Marine Stewardship Council (MSC) Principle 1 — according to independent scientists in a report published by the International Seafood Sustainability Foundation (ISSF).

ISSF 2019-02: An Evaluation of the Sustainability of Global Tuna Stocks Relative to Marine Stewardship Council Criteria attributes this failure to poor stock status, the lack of well-defined harvest control rules (HCRs), and the lack of effective tools to control harvest. Only three of the stocks have well-defined harvest control rules from Regional Fisheries Management Organizations (RFMOs), which continue progressing slowly in this area.

The January 2018 version of the report had found that six out of 19 stocks were being managed to avoid overfishing, meaning the situation has not improved in the last year. While South Pacific albacore Principle 1 score has improved thanks to further progress by WCPFC on this stock’s harvest strategy workplan, two other stocks have seen their overall Principle 1 scores worsen: eastern Pacific bigeye due mostly to uncertainties in its latest stock assessment, and Atlantic yellowfin tuna due to weak tools in place to control exploitation that may be hindering its rebuilding plan.

About the Report

An Evaluation of the Sustainability of Global Tuna Stocks takes a consistent, comprehensive approach to scoring tuna stocks against certain components of the Marine Stewardship Council (MSC) standard. The MSC is a global certification program for fisheries.

The report — updated four times since first published in 2013, and organized by individual tuna stock and tuna RFMO — is designed to:

  • Provide a basis for comparing between stock scores and tuna RFMO scores as assessed by the same experts.
  • Become a useful source document for future tuna certifications or in the establishment of tuna Fishery Improvement Projects (FIPs).
  • Prioritize ISSF projects and advocacy efforts against initiatives that will improve low performance indicator scores.

The scores in the report focus on stock status (MSC Principle 1) and the international management aspects relevant to RFMOs (part of MSC Principle 3) and are based on publicly available fishery and RFMO data. Each of these Principles is evaluated in relationship to Performance Indicators (PIs) within each Principle. The Evaluation report also includes detailed remarks on each stock, evaluations of the four RFMOs, and comprehensive reference citations.

The report does not address bluefin tuna stocks.​

MSC Principle 1

The MSC Principle 1 states: “A fishery must operate in a manner that does not lead to overfishing or depletion of the exploited populations and, for those populations that are depleted, the fishery must be conducted in a manner that demonstrably leads to their recovery.”

Regarding stocks receiving passing scores:

  • Among seven tuna stocks in the Atlantic Ocean, one received an overall principle-level passing score: Northern albacore.
  • Among eight tuna stocks in the Pacific Ocean, three received overall principle-level passing scores: Western skipjack, Eastern yellowfin and Southern albacore.
  • Among four stocks in the Indian Ocean, one received an overall principle-level passing score: skipjack.

Regarding stocks receiving failing scores:

  • In the Pacific, five stocks received overall principle-level failing scores: Western yellowfin, Northern albacore, Eastern bigeye, Eastern skipjack and Western bigeye.
  • In the Indian Ocean, yellowfin, bigeye and albacore all received overall principle-level failing scores.
  • In the Atlantic, yellowfin, bigeye, Western skipjack, Eastern skipjack, Southern albacore and Mediterranean albacore all received principle-level failing scores.
  • Stocks that require rebuilding include Atlantic yellowfin, Atlantic bigeye and Indian Ocean yellowfin.

See a graphic showing MSC Principle 1 averages from February 2013-January 2019.

MSC Principle 3

The MSC Principle 3 states: “The fishery is subject to an effective management system that respects local, national and international laws and standards and incorporates institutional and operational frameworks that require use of the resource to be responsible and sustainable.”

  • One RFMO —IATTC — received passing scores for all seven performance indicators under Principle 3.
  • All four RFMOs received overall principle-level passing scores from the authors.

See a graphic showing MSC Principle 3 averages from December 2013-January 2019.

While the report focuses on tuna stock status and sustainability as well as on RFMO policies, it does not address national or bilateral fishing jurisdictions, gear- or fleet-specific ecosystem impacts, or specific fisheries’ ecosystems — all of which are also considered within the MSC assessment methodology.

Since 2011, ISSF has been an active stakeholder in MSC tuna fishery assessments and certifications. ISSF’s strategic objective is to develop and implement verifiable, science-based practices, commitments and international management measures to help all tuna fisheries become capable of meeting the MSC certification standard without conditions.

Japan’s ‘King of Tuna’ Pays Record $3 Million for Bluefin at New Tokyo Fish Market

January 7, 2018 — The first tuna auction of the year at Tokyo’s new fish market set a high bar on Saturday after a restaurant chain paid a record price — more than $3 million — for a giant bluefin tuna.

The city’s famed Tsukiji fish market was relocated to the new space, in the Toyosu neighborhood, late last year to make way for the 2020 Olympics. The market was well known for its pre-dawn tuna auctions, a tradition that is continuing at the new location.

On Saturday, dozens of buyers walked along row after row of giant tuna, examining the fish before making their bids. The $5.3 billion enclosed, air-conditioned facility at Toyosu is a far cry from the grime and grit of Tsukiji, which served as the city’s main fish market for 83 years.

Sailors for the Sea takes new approach to seafood sustainability in Japan

December 5, 2018 — Ryan Bigelow, the senior program manager for Monterey Bay Aquarium’s Seafood Watch, sees Japan as a country ripe for seafood sustainability ratings like those his program provides.

Japan’s population consumes a vast amount of seafood – collectively, the country has one of the largest seafood consumption footprints in the world (third behind China and the European Union) – and because of that, an improvement in the overall sustainability of the seafood sold and eaten in Japan can have a major impact.

Seafood Watch’s Buyers Guide, which gives seafood either a “best choice,” a “good alternative”, or “avoid” recommendation to seafood commonly found in supermarkets, is well-known in the United States. (Its ratings are color-coded green, yellow, and red, similar to the colors found in traffic signals.)

The guide is tailored to each U.S. state in order to give recommendations relevant to the seafood available there. They can be downloaded in PDF form on a single page and easily folded into a wallet or pocketbook.

But Bigelow openly acknowledges that Japanese consumers are not familiar with Seafood Watch’s guides.

“We don’t promote our program there,” he told SeafoodSource.

Still, for the fourth consecutive year, Bigelow attended the Tokyo Sustainable Seafood Symposium, which took place at Iino Hall and Conference Center on 1 November. Initiated in 2015, the annual event brings together Japanese professionals involved in the seafood industry to discuss issues surrounding smarter management of global fisheries resources. The all-day program featured a wide range of speakers and panelists.

“We attend the symposium to share our experiences advocating for more sustainable seafood in North America, both our successes and our failures,” Bigelow said. “Hopefully, that knowledge allows the sustainable seafood movement in Japan to grow more quickly and avoid some of the issues we encountered over the last 20 years.”

According to Bigelow, the closest parallel to the Seafood Watch Buyers Guide in Japan is the Sailors for the Sea Blue Seafood Guide.

A new way to fish

November 15, 2018 — For several years, biotech companies have been promising “clean” meat, “cell-based” meat, “cultured” meat — whatever you want to call it — as a way to enjoy the taste of chicken, pork and beef without the brutality of animal slaughter or the environmental damage of big agriculture. But what about fish? What about something as prized as buttery bluefin tuna, a delicacy that has become the forbidden fruit of the sea because of the many threats that have landed the fish on threatened and endangered species lists?

Where are the Silicon Valley start-ups promising to free us from the guilt of gobbling down a finger of otoro sushi, the rich bluefin belly meat, without contributing to the decline of the fish or the decline of our own health via mercury that accumulates in the flesh of this apex predator?

Well, there is at least one scientific pilgrim: Brian Wyrwas is the co-founder and chief science officer for Finless Foods, a Bay Area biotech dedicated to growing bluefin tuna in a lab. He can tell you all about the difficulties of his task, starting with the bone-weary process of securing bluefin tuna samples, the pristine source material for much of the science that follows in this field known as cellular agriculture.

Big bluefin tuna make comeback after 80-year hiatus off California coast

October 18, 2018 — Large Pacific bluefin tuna not seen in California waters for decades have reappeared, to the delight of fishing enthusiasts and scientists, as global conservation efforts have proven effective for one of the ocean’s priciest and most sought-after fish.

Overfishing of bluefin tuna spurred by a growing global appetite for sushi resulted in a critical decline in stocks over decades. But measures by the United States, Japan, Mexico and others to limit their take have led to population growth, though tuna populations are still below historic levels.

Gerard DiNardo, director of the Fisheries Resources Division at Southwest Fisheries Science Center, a division of the U.S. National Oceanic and Atmospheric Administration (NOAA) in La Jolla, California, said there has been an increase in population as well as size of the bluefin because of those efforts.

“This is management and effective management and it actually is working'” said DiNardo.

The Center for Biological Diversity said in August 2017 that the Pacific bluefin had been overfished to less than 3 percent of its historic population. The National Marine Fisheries Service announced in October 2016 that it was considering listing the Pacific bluefin, but it subsequently concluded that protections were not warranted.

Australian fisheries declared free from overfishing

October 1, 2018 — Commonwealth fisheries in Australia, the Southern Ocean and the south Pacific managed by Australian Fisheries Management Authority (AFMA) have been assessed as not subject to overfishing.

It is the fifth year in a row the fisheries, which include fisheries for southern bluefin tuna, toothfish, skipjack tuna, billfish, scale fish, squid and shark, have been been declared free from overfishing.

The assessments reported by Australian Bureau of Agricultural and Resource Economics and Sciences (ABARES) in its status reports 2018, assessed 95 species that are either solely or jointly managed by AFMA.

AFMA’s CEO, James Findlay, said the result is a credit to the Australian seafood industry, scientists and fisheries managers.

Japanese proposal for bluefin catch increase rejected

September 14, 2018 — Japan’s proposal for increasing the catch quota of Pacific bluefin tuna by about 15 percent from 2019 has been rejected.

Japan made its request at the committee meeting of the Western and Central Pacific Fisheries Commission (WCPFC) in Fukuoka, Japan, which took place 3 to 7 September. Japan pushed for the quota increase after scientific data showed a recovery in the stock.

The WCPFC has set a mid-term target of increasing stocks of adult Pacific bluefin tuna (those weighing 30 kilograms or more) from the latest estimate of the current 21,000 metric tons (MT) to 43,000 MT in 2024. The scientific committee of the commission announced in mid-July that the probability of achieving the target would be 74 percent if the total catch, including both fish weighing less than 30 kilograms and those over, were to increase by 15 percent from 2019.

Some Good News for Pacific Bluefin Tuna

September 6, 2018 — Although the Pacific bluefin tuna numbers continue to be low, there are signs the population is recovering and rebuilding targets set forth by international agreement are on track to be met. In July 2018, The International Scientific Committee for Tuna and Tuna-Like Species in the North Pacific Ocean (ISC) released the most recent assessment of Pacific bluefin tuna (Thunnus orientalis) and evaluated the likelihood of reaching internationally established rebuilding targets. The bluefin spawning stock biomass (SSB) was estimated to be 3.3% in 2016 relative to their unfished SSB, up from 3.0% in 2014. Unfished spawning stock biomass is the theoretical amount of fish there would be had there never been fishing. The amount and rate of bluefin harvested continues to be high with the greatest catches (and thus impact) on juveniles in the western Pacific Ocean. NOAA Fisheries scientists participate in these assessments and since 2013 the agency has listed Pacific bluefin tuna as overfished and subject to overfishing.

The assessment also projected the stock’s performance based on its status in 2016, management measures in place now, as well as other harvest scenarios. Overall, the analyses indicate that the stock biomass is expected to reach the initial biomass rebuilding target adopted by the Western and Central Pacific Fisheries Commission (WCPFC) by 2024 with a 98% probability, and the second biomass rebuilding target by 10 years after reaching the initial rebuilding target or by 2034, whichever is earlier, with a 96% probability. Experts have not yet determined the amount of biomass that would indicate the population is recovered or rebuilt.

See the 2018 stock assessment and projections

The Inter-American Tropical Tuna Commission is expected to adopt catch limits for 2019 and possibly beyond at its annual meeting in August 2018. Given the projections for achieving the rebuilding targets are optimistic, the WCPFC may consider increasing catches when it meets in December 2018.

The best way to ensure the long-term sustainability of Pacific bluefin tuna is through international cooperation. NOAA Fisheries recognizes concerns about low numbers of Pacific bluefin tuna, and the United States has taken several steps to control the impact of U.S. harvests and has led international action to reduce fishing mortality, rebuild the species, and monitor status.

ISC also assessed the shortfin mako shark and Western and Central Pacific swordfish populations this year and noted no concerns about these stocks.
