Red Snapper in the Gulf show signs of stress after Gulf oil spill

March 12, 2021 — Nearly 100 percent of the red snapper sampled in the Gulf of Mexico over a six-year period by University of South Florida (USF) marine scientists showed evidence of liver damage, according to a study reported in Aquatic Toxicology.

The study is the first to correlate the concentration of crude oil found in the workhorses of the digestive system — the liver, gall bladder, and bile — with microscopic indicators of disease, such as inflammation, degenerative lesions, and the presence of parasites. The team sampled nearly 570 fish from 72 Gulf locations between 2011 to 2017 in the wake of the historic 2010 Deepwater Horizon oil spill.

“The results add to the list of other species we’ve analyzed indicating early warning signs of a compromised ecosystem,” said Erin Pulster, PhD, first author of the study and researcher at the USF College of Marine Science.

Pulster and the team of researchers studying oil pollution in Gulf of Mexico fishes have previously reported high levels of oil exposure in yellowfin tuna, golden tilefish, and red drum as well.

The Gulf of Mexico not only experiences hundreds of annual oil spills with long-lasting effects such as the historic Deepwater Horizon spill in 2010 but is routinely subject to intense shipping traffic and collects pollutants from faraway places that flow in from coastlines and rivers like the Mighty Mississippi and the Rio Grande.

In this study Pulster and the team looked specifically at the most toxic component of crude oil called polycyclic aromatic compounds, or PAHs. PAH sources include old oil and gas rigs, fuel from boats and airplanes, and natural oil seeps, which are fractures on the seafloor that can add millions of barrels of oil to the Gulf every year.

IOTC delays yellowfin decision, WWF declares decision “lost opportunity”

March 12, 2021 — A special session of the Indian Ocean Tuna Commission (IOTC) ended on Friday, 12 March, with the regulatory organization punting on any decision to further reduce limits on yellowfin tuna fishing.

According to environmental non-governmental organization WWF, IOTC member-states failed to agree on a proposal that would have implemented a 20 percent cut in regional yellowfin tuna catches compared to 2014 levels.

ISSF Statement on IOTC March 2021 Special Session – Indian Ocean Fisheries Managers Fail to Act for the Protection of Yellowfin Tuna Stocks

March 12, 2021 — The following was released by the International Seafood Sustainability Foundation:

ISSF and its stakeholders called for immediate action by the Indian Ocean Tuna Commission (IOTC) at its Special Session held virtually from March 8-12 to conserve the region’s overfished yellowfin stock.

Regrettably, this IOTC Special Session failed in its one goal — to agree on a science-based and enforceable rebuilding plan to ensure the long-term sustainable management of the overfished yellowfin tuna stock. The IOTC Scientific Committee’s advice on what was needed to prevent further declines in this overfished stock went unheeded.

We are disappointed that, once again, the Parties to the IOTC could not agree on a measure for managing such a critical resource. Delaying action until the June 2021 Commission Meeting risks further stock declines at a time when some nations already have exceeded existing inadequate yellowfin catch limits — and other parties are exempted from catch limits altogether.

ISSF calls on IOTC Parties to work collaboratively between now and June to develop a robust, science-based and enforceable conservation measure to rebuild the Indian Ocean yellowfin stock in two generations.

ISSF recognizes that the impacts of COVID-19 continue to challenge RFMOs in conducting their meetings but finds no reason that needed management action cannot be agreed to virtually.

ISSF will continue to pursue all opportunities to help guide IOTC and all tuna RFMOs, member governments, industry, vessels, FIPs and NGOs on the complex issues we must navigate together for sustainable global tuna stocks and their ecosystems.

MARCEL KROUSE: IOTC should approve yellowfin tuna catch cap

March 9, 2021 — Marcel Kroese is WWF’s global tuna lead and has been involved in marine conservation as a researcher and professional since 1992, with working experience in East and West Africa, the Pacific, and Central America.

Picture a tuna. No, not a can. A fish. It is sleek and strong. Its scales flash as it dives like a torpedo to depths of 1,000 meters. If it were a car, James Bond would drive it. If it were a cat, it would be a cheetah. Yet these spectacular, athletic sea creatures are not afforded the same awe and wonder by humans as the big cats. We value tuna as a luxury food or a more humble “shelf-stable protein,” which is handy when stocking up for a pandemic. Either way, they are just food.

Certainly, tuna have fed countless generations throughout human history. From the palm-fringed islands of the Pacific to the diverse nations of the Mediterranean, tuna have been part of the diet and part of the culture. But before they make it to the plate, they played a vital role in the functioning of the ocean ecosystem – because fish don’t just inhabit the ocean. They fuel it.

Pressure builds for IOTC ahead of special session, with several groups calling for urgent action

March 5, 2021 — Many seafood supply chain players and industry stakeholders are calling on the Indian Ocean Tuna Commission (IOTC) for reforms as concerns surrounding heavy fishing in the region reach a boiling point in advance of the commission’s next meeting, set to run from 8 to 12 March, 2021.

The Global Tuna Alliance, the Tuna Protection Alliance, and several seafood companies are urging the inter-governmental organization – which is responsible for the management of Indian Ocean tuna fisheries – to impose an overall 20 percent cut in regional yellowfin tuna catch compared to 2014 levels.

Concerns emerge over IOTC delay of yellowfin tuna conservation plan

February 8, 2021 — The Indian Ocean Tuna Commission (IOTC) will maintain the status quo for the current yellowfin tuna conservation measures, barely three months after the organization had scheduled an emergency meeting for March 2021 to review its conservation plan.

In November 2020, the IOTC said its March 2021 meeting would focus on emerging trends of overfishing of yellowfin tuna, which delayed the stock’s rebuilding plan. However, advice issued 29 January by the IOTC’s scientific committee called on IOTC member-states to maintain the status quo until a new stock assessment is completed, likely to occur later this year.

IOTC publishes 2021 yellowfin tuna catch limits

January 8, 2021 — The Indian Ocean Tuna Commission (IOTC) has published a new list of yellowfin tuna catch limit allocations for 2021.

A statement by IOTC Executive Secretary Christopher O’Brien said the commission is focused on the rebuilding of the Indian Ocean yellowfin tuna stock, hence the annual allocation of catch limits for affiliated members under the organization’s Resolution 19/01.

IATTC agrees to rollover tropical tuna quotas to 2021

December 22, 2020 — The Inter-American Tropical Tuna Commission (IATTC) agreed at a special session on 22 December to a rollover of its existing quotas for tropical tuna in the eastern Pacific for 2021.

The tropical tuna fishery – which includes bigeye, yellowfin, and skipjack tuna stocks – brings in billions of dollars’ worth of fish annually. At its annual meeting earlier this month, the commission failed to reach a consensus on the management of tropical tunas by one vote – with Colombia opposing the resolution – leaving tuna fisheries without any rules of governance starting on 1 January.

WCPFC secures consensus to continue tropical tuna measure

December 16, 2020 — The 27 members of the Western and Central Pacific Fisheries Commission (WCPFC) have approved the rollover of the tropical tuna measure for bigeye, skipjack, and yellowfin tuna, which without a consensus would have expired in February 2021.

The move by the WCPFC is in contrast with the Inter-American Tropical Tuna Commission (IATTC), which failed to reach a consensus on regulations, leaving the fishery unmanaged beginning 1 January, 2021. The renewal by the WCPFC is considered a victory, but the Pacific Islands Forum’s Fisheries Forum Agency (FFA) said much work remains left to be tackled at next year’s tuna commission.

MSC calls for sustainable management of tropical tuna in Eastern Pacific

December 16, 2020 — The following was released by the Marine Stewardship Council:

From 1 January there could be no restrictions for tropical tuna fishing in nearly half of the Pacific Ocean, increasing the risk of overfishing of commercially important skipjack, yellowfin and bigeye tunas, the Marine Stewardship Council warns, unless all the member governments reach an agreement on how to manage these stocks in 2021.

The MSC standard requires fisheries certified to its globally recognised standard to limit their catch within sustainable limits. Robust management is one of the fundamental principles of sustainable fisheries, especially for those catching highly migratory species such as tuna, as it prevents overfishing.

However, the body responsible in international law[i] for agreeing how much tuna is safe to catch is yet to reach a consensus on important measures to restrict tuna catch in the Eastern Pacific Ocean in 2021. Scientific advice recommended to carry over the rules set for 2020 into 2021.

After the Inter-American Tropical Tuna Commission (IATTC) failed to reach an agreement at their meeting earlier this month, the Chair of IATTC has called an extraordinary meeting of the delegations on 22 December, recommending carrying over the 2020 management measures into 2021 and holding a series of further meetings in 2021 to develop the way tuna stocks are managed in the Eastern Pacific Ocean.

IATTC had previously agreed management measures for skipjack, yellowfin and bigeye in the Eastern Pacific Ocean. Having such measures in place even when stocks are perceived as healthy enables fisheries to act quickly when needed.

With increased demand for tuna globally comes increased pressure on tuna stocks and associated ecosystems. At present 17.5 % of the world’s tuna fisheries are overfished.

The Marine Stewardship Council’s Chief Science and Standards Officer, Dr Rohan Currey, said:

“We welcome IATTC’s decision to convene an extraordinary meeting, reflecting the critical importance of maintaining the conservation measures for tropical tuna stocks.  The nations involved must find a way to reach a consensus that will protect the future health of these economically important stocks, that reflects scientific advice and is grounded in a robust long-term management plan.

“Nations have a duty to come together to manage fisheries and their impact on the oceans. If the IATTC cannot agree on how to manage this tropical tuna fishery, it will have effectively abandoned this duty, putting the future of the stocks at risk. We join with others in expressing deep concern about this and urge the delegates to reach a speedy decision on this at their extraordinary meeting on 22 December.”
