PNA data offers a better understanding of drifting FADs

October 10, 2019 — In recent years, concern has been growing about bycatch of juvenile bigeye tuna by purse-seiners setting nets on drifting fish aggregation devices (dFADs). The main target of the purse-seiners is the more plentiful skipjack tuna, but as bigeye inhabit the same tropical seas, they are often taken as well.

The devices typically consist of a raft or buoy trailing a length of disused netting tied into the shape of a string of sausages, used to attract tuna – which like to gather under floating objects. Modern dFADs are equipped with a solar-powered GPS device and a fish finder to report their location and the amount of fish gathered under them. Support vessels manage the deployment and retrieval of the dFADs, so that fishing vessels can concentrate on fishing.

Pacific fisheries ministers push for WCPFC reforms

June 11, 2019 — Fisheries ministers in the Pacific said while stocks of bigeye, yellowfin, albacore, and skipjack tuna are all to be in a healthy condition in the Western and Central Pacific Ocean, there should be no room for complacency on management measures as it could “lead to increased commercial pressure on those fisheries.”

The Parties to the Nauru Agreement is made up of the Federated States of Micronesia, Palau, the Marshall Islands, Kiribati, Tuvalu, Nauru, the Solomon Islands, Papua New Guinea, and Tokelau, which collectively maintain a purse-seine vessel day scheme (VDS). According to a communique signed by the ministers at the end of the annual PNA meeting in Palau on 30 May, all tuna stocks in the region are at healthy levels.

Scientists with the Pacific Community or SPC has earlier reported that Western and Central Pacific tuna stocks are healthy compared to other stocks in other oceanic regions due to the conservation measures implemented by PNA. The total annual tuna catch in PNA waters is around 1.6 million metric tons, including about 50 percent of the world’s supply of skipjack tuna. About half of the total tuna catch from PNA waters, or about 790,000 metric tons, is certified by the Marine Stewardship Council.

“Ministers welcomed the scientific advice that all major tuna stocks in PNA waters were reported as healthy and none were assessed as overfished or subject to overfishing,” the announcement stated.

However, the PNA statement said maintaining healthy tuna stocks is only possible with a continued effort to strengthen regional management of the fisheries.

ISSF Sponsors Global Contest to Reward Marine Science Scholars’ Innovative Ideas for Sustainable Tuna Fishing

March 13, 2019 — The following was published by The International Seafood Sustainability Foundation:

Marine-science graduate students and postdoctoral researchers interested in helping to pioneer the next generation of sustainable tuna fishing initiatives — especially to reduce bycatch and protect ocean ecosystems — are invited to submit their ideas to the first-ever International Seafood Sustainability Foundation (ISSF) Seafood Sustainability Contest.

The contest opens today to eligible individuals and teams worldwide, who have until midnight December 31, 2019, to submit online entries. Competition judges will announce one $45,000 Grand Prize winner and one $10,000 Runner-Up Prize winner on February 28, 2020. The Grand Prize includes a trip (airfare and travel expenses paid for) for the winning individual or team representative to attend a major tuna sustainability conference or event selected by ISSF with the potential to present the winning idea to diverse stakeholders. Watch a video about the contest.

Tuna species provide a critical source of food and nutrition, economic benefits, and employment opportunities throughout the globe. Tuna comprise a massive 5 percent of the total worldwide fish trade and help contribute to a value chain estimated to be worth $42 billion, making it among the world’s most valuable fish. Commercial tuna fishing, regardless of the fishing method, must be practiced and managed as sustainably as possible to prevent overfishing and to protect other marine species and ocean ecosystems that can be impacted by commercial fishing practices.

Contest Launches 10th Anniversary Celebration

The ISSF Seafood Sustainability Contest inaugurates the commemoration of ISSF’s first “decade of discovery” (2009-2019), which has been marked by productive partnerships with marine scientists, seafood companies, vessels, Regional Fisheries Management Organizations (RFMOs), charitable foundations, retailers, and fellow NGOs. “Ten years ago, ISSF formed out of a shared vision and commitment that more could be done — and needed to be done — for the protection and long-term sustainable use of tuna stocks,” said ISSF President Susan Jackson. “A great deal has been accomplished over that time period, and we’re proud of the legacy we’ve built as ambassadors for science and as collaborators with the diverse collection of NGOs, foundations, retailers, and fishers working in this space. Our tenth-anniversary Seafood Sustainability Contest will allow us to tap into a talented pool of up-and-coming marine science students. We can’t wait to dive into their ideas, and are eager to support potential solutions that result from it.” To complement and enrich ISSF’s scientific program — which encompasses at-sea research, skippers workshops, and technical reports, for example — the Seafood Sustainability Contest seeks innovative proposals for achieving one or more of these goals in tropical tuna purse-seine fisheries that use Fish Aggregating Devices (FADs), which harvest most of the world’s tuna

A panel of five judges composed of experts drawn from academia and the fishing industry will determine the winners based on the originality of the idea, conservation impact, impact on skipjack catches, the degree to which idea has been tested, the feasibility of industry-wide implementation, and cost-effectiveness.

Before preparing and submitting entries to the Contest, participants must read the official rules. (No purchase necessary. Void where prohibited.)

A Decade of Discovery

In 2009, acclaimed scientists, leaders in the industry, and environmental champions launched the International Seafood Sustainability Foundation (ISSF) based on shared concerns about the future of global tuna fisheries and a desire to do something about it — together.

ISSF has worked for the long-term conservation and sustainable use of global tuna fisheries through its three pillars of Science, Influence, and Verification:

· Tuna Conservation: Through regular status of the Stocks Reports, ISSF creates a window into tuna-stock assessments on a global scale for management, science, and conservation interests.

· Bycatch Mitigation: Through-sea research, ISSF-supported scientists uncover new lessons, develop ideas and solutions, and implement strategies and tactics for bycatch mitigation. ISSF develops and disseminates their discoveries and best practices through globalSkippers Workshops.

· Seafood Company Compliance: ISSF evaluates participating company compliance with all ISSF Conservation Measures – including an emphasis on traceability from product to processing facility to fishery to vessel – and communicates those results publicly to promote transparency.

· Advocacy: Along with NGO partners and other allies, ISSF regularly advocates for critical new RFMO measures to improve global conditions around IUU fishing, deployment of monitoring, control and surveillance technology, harvest control rules, increased observer coverage, and improved data collection.

· ProActive Vessel Register: Through the ProActive Vessel Register(PVR), ISSF manages and updates a publicly accessible database of 1,000+ vessels, across all gear types, committed to transparency in their adherence to science-backed and auditable fishing practices. ISSF launched a new 5-year Strategic Plan in 2018, which formalized support for fisheries improvement activities. Visit the Strategic Plan microsite to learn more.

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.

Bumble Bee: Trump’s tuna tariffs ‘devastating’ for firm

September 21, 2018 — US tuna canning company Bumble Bee Foods warned the US Trade Representative (USTR) in a letter that the now-confirmed tariffs against imports of Chinese tuna would be “devastating” for the firm.

The tariffs — which will come into play on Sept. 24 at 10%, and then go to 25% on Jan. 1, 2019 — will hit US imports of yellowfin, skipjack, and albacore tuna loins, all of which are required by Bumble Bee’s Santa Fe Springs, California factory, wrote CEO Jan Tharp.

The tariffs, which were initially proposed by USTR on July 10, will hike the cost of raw materials, which in turn will “certainly lead to higher prices for US consumers”, Bumble Bee’s leader said.

“We are very concerned with the proposed tariff on tuna loins and the impact that these tariffs will have on our supply chain, global competitiveness, and US operations,” Tharp said. “The proposed tariff on tuna loins will have a devastating effect on Bumble Bee given that our business model is to import tuna loins for further processing and canning in the US by American workers.”

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.

PNA Tuna Fishery Receives MSC Recertification After IPNLF Objections

March 29, 2018 — SEAFOOD NEWS — The PNA tuna fishery has received their MSC recertification following concerns raised by the International Pole and Line Foundation (IPNLF).

As we reported earlier this month, an independent adjudicator confirmed that the PNA skipjack tuna fishery continued to meet the Marine Stewardship Council’s (MSC) standard for sustainable fishing. This inspection came after IPNLF presented 24 objections against the sustainable fishery, including that the fishery was involved in shark finning, a practice that the MSC had banned in 2013.

“This highlights the strength of the MSC process,” MSC Science and Standards Director Dr. David Agnew said in a press release following the Independent Adjudicator’s findings. “As a result of this objection, more information is now in the public domain about the PNA fishery, adding to the information in the published assessment report, and improving the transparency of the fishery’s management. This confirms that the PNA skipjack tuna fishery is a sustainable and well-managed fishery that has made considerable improvements over the course of its first MSC certificate. People buying labeled PNA tuna can be confident that their purchase is making a positive difference to the sustainability of our oceans.”

The MSC certificate is good for five years and confirms that the PNA free-school fishery meets the “robust criteria of the MSC.” In addition, free-school tuna caught in the Exclusive Economic Zone off Tokelau is now eligible for MSC certification under the new MSC certificate.

State of Tuna Stocks Worldwide Assessed in Comprehensive ISSF Report

Global tuna catch stays at 78% healthy level

March 8, 2018 — WASHINGTON — The following was released by the International Seafood Sustainability Foundation:

Of the total tuna catch in 2016, 78% came from stocks at “healthy” levels, unchanged since last reported, according to a February 2018 International Seafood Sustainability Foundation (ISSF) Status of the Stocks report. Skipjack tuna stocks — at healthy levels in all ocean regions — constituted more than one-half of the 2016 total catch.

One notable change in stock status in the February 2018 Status report is for Southern bluefin tuna, a stock that has moved from orange to yellow in abundance ratings. Stock abundance is low, about 13% of the unfished level. However, the stock is rebuilding continuously as a result of the implementation of a robust Management Procedure (a Harvest Strategy) by the Commission for the Conservation of Southern Bluefin Tuna, the regional organization in charge of managing the stock. In contrast, the Pacific bluefin stock, along with the Indian Ocean yellowfin stock and the Atlantic Ocean bigeye stock remain overfished. See Tables 1 and 2 in the report for specific rating changes.

There were no dramatic changes in tuna stock status since the previous November 2017 Status report; the updated report reflects new data made available at late 2017 tuna Regional Fisheries Management Organization (RFMO) meetings.

Updated several times per year, Status of the Stocks assigns color ratings (green, yellow or orange) on stock heath, stock management, and ecosystem impact. The report ranks the 23 stocks of major commercial tunas around the world using a consistent methodology.

Key Statistics in the Report

Total catch: In 2016, the total major commercial tuna catch was 4.9 million tonnes, a 2% increase from 2015. More than half of the total catch (57%) was skipjack tuna, followed by yellowfin (30%), bigeye (8%) and albacore (4%). Bluefin tunas (3 species) accounted for only 1% of the global catch. These percentages changed only slightly from the Nov. 2017 reporting period.
Abundance or “spawning biomass” levels: Globally, 57% of the 23 stocks are at a healthy level of abundance, 13% are overfished, and 30% are at an intermediate level.
Stocks receiving orange scores, indicating overfished status, include Atlantic Ocean bigeye, Pacific Ocean bluefin and Indian Ocean yellowfin.
Fishing mortality levels: 65% of the 23 stocks are experiencing a well-managed fishing mortality rate, and 13% are experiencing overfishing (with no change from the previous report).
Largest catches by stock: The three largest catches in tonnes are Western Pacific Ocean skipjack, Western Pacific Ocean yellowfin, and Indian Ocean skipjack.
Tuna production by ocean region: Most (53%) of the world’s tuna is harvested from the Western and Central Pacific Ocean, followed by the Indian Ocean (20%), Eastern Pacific Ocean (13%), and Atlantic Ocean (10%).
Tuna production by fishing gear: 65% of the catch is made by purse seining, followed by longline (12%), pole-and-line (8%), gillnets (3%) and miscellaneous gears (12%). These percentages changed only slightly from the Nov. 2017 reporting period.

About the Report

ISSF produces two reports annually that seek to provide clarity about where we stand — and how much more needs to be done — to ensure the long-term sustainability of tuna stocks: the Status of the Stocks provides a comprehensive analysis of tuna stocks by species, and the Evaluation of the Sustainability of Global Tuna Stocks Relative to Marine Stewardship Council Criteria (MSC) provides scores for the stocks and RFMOs based on MSC assessment criteria. The MSC-certified fisheries list (Appendix 2) in Status 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.

MSC: Ocean Naturals and Kraft Heinz Offer Sustainable, Traceable Tuna from Ocean to Plate

March 6, 2018 — SEATTLE — The following was released by the Marine Stewardship Council:

Food service restaurants who serve Ocean Naturals brand tuna from Kraft Heinz are serving seafood that supports the fishermen and fisherwomen who are working hard to meet the world’s most rigorous standard for sustainable fishing. Kraft Heinz has achieved Marine Stewardship Council (MSC) Chain of Custody (CoC) certification for their skipjack and albacore tuna, which is sold to food service operators in the United States for tuna sandwiches and tuna salads.

Kraft Heinz has obtained Chain of Custody (CoC) certification demonstrating their commitment to the sustainability of the fishery. With CoC certification, they can provide restaurant operators with confidence in the sustainability credentials of the Ocean Naturals tuna supplied by The Tuna Store, a part of the Tri Marine Group, that they use in their sandwich and salad recipes.

“This is tuna with not only great sustainability credentials but also a very rich and compelling story about tuna dependent island communities catching and producing quality tuna products for the U.S. market, ” according to Joe Hamby CEO of The Tuna Store.

The MSC is an international non-profit organization, established to safeguard seafood supplies for the future. Recognized as the world’s leading certification program for sustainable, wild-caught seafood, the MSC works with leaders within the fishing industry and seafood sector to create a more sustainable seafood market.

All tuna served at dining institutions in the U.S. market that use Ocean Naturals tuna is sourced from a sustainable and well-managed fishery. Ocean Naturals Skipjack tuna now comes from the Solomon Islands and island cannery Sol Tuna while the Albacore is sourced from the Cook Islands fishery. Roughly 13 percent of the annual global harvest of wild-capture fisheries are MSC certified.

“We congratulate Kraft Heinz on attaining MSC Chain of Custody certification and joining The Tuna Store in providing sustainable tuna options in the U.S.” said Brian Perkins, MSC regional director, Americas. “The MSC sets robust and credible requirements for organizations handling MSC certified seafood, and we’re proud that The Tuna Store and Kraft Heinz are among those taking the lead in seafood sustainability.”

Because Ocean Naturals tuna is offered in food service establishments (i.e. – delis, cafeterias, food service restaurants, etc.), consumers may not be aware that they’re eating certified, sustainable seafood. Kraft Heinz intends on focusing on chefs, food operators, and buyers who can feel good about serving MSC-certified tuna and in turn passing the benefit on to the consumer.

About the MSC

The Marine Stewardship Council (MSC) is an international non-profit organization. Our vision is for the world’s oceans to be teeming with life, and seafood supplies safeguarded for this and future generations. Our ecolabel and certification program recognises and rewards sustainable fishing practices and is helping create a more sustainable seafood market.

The MSC ecolabel on a seafood product means that:

It comes from a wild-catch fishery which has been independently certified to the MSC’s science-based standard for environmentally sustainable fishing.
It’s fully traceable to a sustainable source.

More than 300 fisheries in over 34 countries are certified to the MSC’s Standard. These fisheries have a combined annual seafood production of almost nine million metric tonnes, representing 12% of global marine catch. More than 25,000 seafood products worldwide carry the MSC label. For more information visit www.msc.org

Independent Adjudicator Finds No Shark Finning Issue in PNA Tuna Fishery

March 2, 2018 — SEAFOOD NEWS — Following concerns brought up by the International Pole and Line Foundation, an Independent Adjudicator has confirmed that the PNA skipjack tuna fishery “continues to meet the Marine Stewardship Council’s (MSC) standard for sustainable fishing.

Although the International Pole and Line Foundation raised a “number of concerns,” one of the bigger issues revolved around the group’s claim that the PNA skipjack tuna fishery is involved in shark finning. MSC had banned the practice of shark finning in 2013, and a ban was also put in place by the PNA governments. According to the MSC, shark finning now only occurs in “isolated cases.” The Independent Adjudicator dismissed the claims of shark finning in the fishery, saying that it is “unrealistic” to make a fishery ineligible for certification based on a single incident. An auditor has recommended that the PNA continue to prosecute shark finning offenders and maintain enforcement actions.

“This highlights the strength of the MSC process,” MSC Science and Standards Director Dr. David Agnew said in a press release. “As a result of this objection, more information is now in the public domain about the PNA fishery, adding to the information in the published assessment report, and improving the transparency of the fishery’s management. This confirms that the PNA skipjack tuna fishery is a sustainable and well-managed fishery that has made considerable improvements over the course of its first MSC certificate. People buying MSC labelled PNA tuna can be confident that their purchase is making a positive difference to the sustainability of our oceans.”
