Saving Seafood

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.

Japan to Propose Bluefin Tuna Catch Quota Increase At WCPFC Meeting

August 2, 2018 — SEAFOOD NEWS — The government plans to propose raising catch quotas for Pacific bluefin tuna — a popular component of high-grade sushi — in September, following an international body’s recent estimate that it is feasible to increase catches by up to about 15 percent from 2019, thanks to a recovery in the stock.

Overfishing has drastically declined bluefin stock to about 10 percent of its peak level of 168,125 tons in 1961. Since 2015, the Western and Central Pacific Fisheries Commission has set caps on catches to strengthen the management of the resource. The commission has 26 member countries and regions, including Japan and the United States.

The WCPFC has set a mid-term target of increasing stocks of adult Pacific bluefin tuna weighing 30 kilograms or more, from the latest estimate of about 21,000 tons to 43,000 tons in 2024. At the same time, the commission has adopted a policy of allowing higher catch quotas once the probability of achieving the target reaches 70 percent or more.

An international organization comprising experts in such fields as fishery survey announced in mid-July that the probability of achieving the target would be 74 percent if total catches — which combine small-sized fish weighing less than 30 kilograms and large ones of 30 kilograms or larger — increase by 15 percent from 2019.

This has led Tokyo to plan to propose increasing catch quotas at a September committee meeting of the WCPFC in Fukuoka Prefecture, in the hope of obtaining understanding from respective countries and regions. The government is working out details of the proposal, such as a specific increase in catch quotas for both small and adult fish.

Bluefin tuna caught in the Pacific Ocean accounts for 60 percent of the Japan market. The nation’s catch quota is set at 4,007 tons for small fish — about half of the average in previous years — and 4,882 tons for adult fish, which is equivalent to this category’s average.

Atlantic bluefin tuna stocks have also plunged due to overfishing, but strict regulations — such as prohibiting fishing small ones in principle — have subsequently been successful, resulting in a decision to raise catch quotas.

Conservation groups disagree with NOAA decision on Western Atlantic bluefin

May 22, 2018 — The decision by NOAA Fisheries to remove Western Atlantic bluefin tuna is not sitting well with conservationists.

Last week, the agency released its Status of U.S. Fisheries report for 2017. In it, officials announced that the number of stocks on the overfished list had dropped to 35, an all-time low. The Western Atlantic bluefin was among six stocks removed from the overfished list. NOAA, in a press release, said “significant scientific uncertainty” about the stock after last year’s assessment led to the ruling.

To be placed on the overfished list, NOAA officials must determine the stock’s population is too small. That differs from the overfishing list, where stocks with an excessive catch rate land. Overfished stocks may not necessarily be subject to overfishing currently, however, the stock cannot produce a maximum sustainable yield in its present condition. Other factors, such as environmental changes, also may put a stock on the overfished list.

ISSF Releases Interactive “Status of the Stocks Tool”

April 5, 2018 — WASHINGTON — The following was released by the International Seafood Sustainability Foundation:

The International Seafood Sustainability Foundation (ISSF) has developed a new data-visualization tool based on its long-running and widely followed Status of the Stocks report. The “Status of the Stocks Tool” is located on the ISSF website and accessible through the Status of the Stocks overview page; users can easily toggle through tuna stock health indicators and filter by location, species and other key stock health and catch factors.

The tool, which requires no additional applications or access to use, offers fisheries managers, fishers, RFMOs, scientists, and other stakeholders a convenient and intuitive resource for visualizing the state of tuna stocks worldwide, covering 23 tuna stocks — including ones that have been or are overfished, as well as those at healthy levels. Offering the most current data available, it also pulls information from previous years of ISSF Status of the Stocks reports, which compile key stock health and catch data from the Regional Fisheries Management Organizations (RFMOs).

“As part of our ongoing efforts to bring improved technology into understanding fisheries management, we developed this resource to offer a clearer picture of trends in global tuna stock health over time,” said ISSF President Susan Jackson. “Not only does a data visualization tool such as this allow users a customized look at the tuna stocks they are most interested in, it also offers a meaningful understanding of the impact of changes in RFMO management on those tuna stocks over time.”

For example, the number of stocks well-managed in terms of fishing mortality has increased from 8 (35%) in 2012 to 15 (65%) in 2018, demonstrating the improvement of management measures put in place by the RFMOs. Improved management measures lead to stock rebuilding, as in the case of bluefin tuna stocks, where 100% of the catch came from overfished stocks in 2013, versus just 26.5% of the catch in 2018. The tool can also be used to monitor those stocks for which management has been effective and, therefore, resulted in maintained healthy levels of abundance over time (e.g., skipjack stocks).

The tool was developed by ISSF’s science and communications teams and was reviewed by the scientists on the ISSF Scientific Advisory Committee.

Interactive Tool Design

The tool, built using Tableau technology, features two tabs — one for visualizing tuna stock health trends since 2011, and another for visualizing the recent tuna catch by fishing method.

Users can generate a variety of customized and exportable graphics within the tool based on the parameters they choose in the checkboxes (such as “ocean location”) or buttons. By hovering or clicking on the graphics, users can see percentages and other details.

On the Stock Health tab, data can be filtered first by tuna species and ocean region. The user can choose between visualizing data relative to total catch or to number of stocks, and between ratings on stock abundance or on fishing mortality. As a result, the corresponding area graph is generated. Like the Status of the Stocks reports, the tool uses a color rating system: green (“healthy”), yellow (“intermediate”), and orange (“needs improvement”).

The Catch tab currently features data from 2016, the most recent year for which complete catch data are available. Gear type data can be filtered by ocean location to generate a bar chart.

ISSF’s “Status of the Stocks Tool” will be updated as new iterations of the Status of the Stocks Reportare released. To access the most recent Status of the Stocks report in full, click here.

About the ISSF Status of the Stocks Report

There are 23 stocks of major commercial tuna species worldwide – 6 albacore, 4 bigeye, 4 bluefin, 5 skipjack, and 4 yellowfin stocks. The Status of the Stocks summarizes the results of the most recent scientific assessments of these stocks, as well as the current management measures adopted by the RFMOs. This report ranks the status and management of the 23 stocks using a consistent methodology based on three factors: Abundance, Exploitation/Management (fishing mortality) and Environmental Impact (bycatch).

ISSF also produces a complementary report, the Evaluation of the Sustainability of Global Tuna Stocks Relative to Marine Stewardship Council Criteria (MSC) which provides scores for the stocks and RFMOs based on MSC assessment criteria. The MSC-certified fisheries list (Appendix 2) inStatus of the Stocks complements the Evaluation report.

Together, these tools help to define the continuous improvement achieved, as well as the areas and issues that require more attention. Access the newly updated ISSF stock status ratings here.

Climate change threatens coastal life as we know it

March 9, 2018 — The Gulf of Maine is getting warm — quick. From 2004–2013, sea temperatures there rose faster than almost any other location on Earth.

Why it matters: The Gulf is home to a number of endangered species, and the fisheries there bring in several billion dollars per year to the U.S. and Canada, but the Gulf’s future hangs in the balance. Researchers are scrambling to understand what the warming water means for the people and animals who rely on the ecosystem, particularly as the changes there provide a glimpse into the future of coastlines around the world.

Why it’s warming

The Gulf of Maine lies at the intersection of several major ocean currents, including the Atlantic meridional overturning circulation, which moves dense, cold water down and toward the equator. Fresh water from melting sea ice seems to be weakening this current, which could be causing the Gulf to warm faster than other regions.

A combination of cold winters, warm summers, and dramatic tides make the Gulf one of the most productive ecosystems in the ocean. It’s a critical habitat for right whales, seabirds like puffins, humpback whales, bluefin tuna and other species.
