Study shows how local fishers respond to climate challenges

February 22, 2024 — When it comes to protecting a crucial resource in the face of changing conditions, it’s important to know how the humans reliant on that resource have organized themselves. Especially if there isn’t a lot of government supervision.

A new study of small-scale fisheries in Mexico’s Gulf of California has found that the fishers’ response to a changing climate can be strongly influenced by what they fish for and how they’re organized. The work appears in the January 2024 issue of Global Environmental Change.

“When we study climate change adaptation, we haven’t paid nearly enough attention to how those fishers, these farmers, these water irrigators are organized,” said Xavier Basurto, the Truman and Nellie Semans/Alex Brown & Sons Professor of sustainability science at the Duke Marine Lab and senior Co-Principal Investigator of this research project.

Their organization, or self-governance, turns out to be key.

Scientists Record 4 Collapses in Sardine Population in the Gulf of California

May 10, 2021 — In the last 30 years, overfishing and alterations caused by Climate Change decimated the number of individuals and their fishing fell from 300 thousand tons per year to only 10 thousand

Sardine capture in the Gulf of California has fallen from 300,000 tons per year to just 10,000 tons per year, in four different cycles since 1991. An international scientific study published last Tuesday in the Canadian Journal of Fisheries and Aquatic Sciences concluded that radical population declines in sardines, called collapses, are caused by the combination of overfishing and alterations caused by climate change.

Researchers: Gulf Of California Sardine Fishery In Trouble

May 5, 2021 — The gulf’s sardine fishery has collapsed four times in the past 30 years, and researchers in California worry about the future of the sardine industry.

Alfredo Giron of Stanford University and Octavio Aburto of the Scripps Institution of Oceanography looked at how sardines are faring.

The study shows that there are natural boom-bust cycles where the small fish are plentiful and then scarce.

U.S. bans more Mexico seafood imports to protect vaquita porpoises

March 11, 2020 — Almost all Mexican shrimp and fish caught from the northern Gulf of California was barred from U.S. trade March 4, as NMFS invoked the Marine Mammal Protection Act in a bid to stop use of gillnets blamed for entangling endangered vaquita porpoises.

The porpoises’ population had already plunged from an estimated 560 animals in the 1990s to 30 surviving by 2017, when the Mexican government officials banned most gillnets in the area.

But the rule was poorly enforced, and the NMFS import ban puts more pressure on the government to carry out blanket prohibition and enforcement that environmental groups and marine scientists say are the only chance for saving the porpoises.

“Mexico has no choice but to eliminate the destructive fishing taking place in the northern Gulf of California that is driving the vaquita to extinction,” said Zak Smith, a senior attorney with the Natural Resources Defense Council. “It’s the only hope the vaquita has for survival, and it is required if Mexico wants to resume exporting these products to the United States.”

US to enforce ban on shrimp, other fish caught in Mexico’s Gulf of California

March 6, 2020 — US importers of Mexican shrimp and other seafood should soon be prepared to present documentation certifying that any of the products they are bringing over the border do not match a list of roughly five species caught in the upper Gulf of California using multiple gear types.

The US’ National Marine Fisheries Service (NMFS) announced Wednesday that it will ban the import of virtually all Mexican shrimp and other fish caught in that region of the country over concerns about the endangered vaquita porpoise. An effective date has not yet been set, but it is expected to be within a month and require importers to maintain a “certification of admissibility” that is signed by a Mexican government official establishing that the products being shipped are not from the upper Gulf of California’s:

shrimp trawl fishery, for both small and large vessels;
shrimp suripera fishery;
sierra purse seine fishery;
sierra hook and line fishery;
chano trawl fishery, for small vessels;
curvina purse seine fishery; or
sardine/curvina purse seine fishery, for both small and large vessels.

Latest surveys show vaquita porpoise population at less than 19 individuals

August 6, 2019 — A new survey published in Royal Society Open Science has dire news for the survival of the vaquita porpoise – a small porpoise that lives in an area of the Mexican coast in the Gulf of California.

Using passive acoustic survey devices – which detect the vaquita due to the species’ use of echolocating “clicks” – the report determined that fewer than 19 individual vaquitas remained as of autumn 2018. The acoustic surveys, which started in 2011, have shown a 99 percent decline in the detection rate of the animals.

Population of Critically Endangered Vaquita Porpoises Now Less Than 19 Individuals

August 1, 2019 — There are now less than 19 individual vaquita porpoises left in the wild, according to an alarming new survey. Scientists say immediate measures are now required to save this enigmatic species from extinction.

If fishing nets continue to be used illegally off the coast of Mexico, vaquita porpoises (Phocoena sinus) will likely become extinct within a year, according to new research published today in Royal Society Open Science. This species, which lives exclusively in the upper Gulf of California, is listed by the IUCN as Critically Endangered. As the new research shows, and despite measures taken by the Mexican government in 2015 to crack down on the use of illegal nets, the population of vaquita porpoises continues to decline.

Vaquita porpoises are the world’s smallest cetacean. On average, females measure around 140 centimeters (55 inches) in length, while males are slightly shorter at 135 centimeters (53 inches) long. Vaquitas, which translates to “small cow” in Spanish, have a gray or white complexion, a tall dorsal fin, dark eye rings, and long flippers.

Seafood importers backing groups in protecting vaquita

March 18, 2019 — The following was released by the Sustainable Fisheries Partnership:

Sustainable Fisheries Partnership (SFP) is pleased to announce eight US importers of Mexican seafood—Aquastar, Artisan Catch (Orca Foods LLC), Del Pacifico, Inland Seafood, Meridian Products, Ocean Garden Products, Santa Monica Seafood, and Seattle Fish Company—have joined together to donate $12,000 to VaquitaCPR to fund removal of illegal fishing gear from the upper Gulf of California.

All eight companies participate in a Mexican Seafood Supply Chain Roundtable (SR) facilitated by SFP for managing ongoing sustainability improvement efforts.

The vaquita porpoise in the upper Gulf of California is critically endangered. The most recent population estimate (2018) indicates, at most, only 22 individuals. Though gillnets were banned from the upper Gulf of California throughout the vaquita’s native range in 2017, illegal use of gillnets by totoaba poachers and shrimp fishermen has continued and is threatening the existence of the vaquita.

“Unless this decline can be stopped by eliminating mortality in illegal gillnets, the vaquita will be extinct in a few years,” said the authors of a 2017 report from the 10th meeting of the Comité Internacional para la Recuperación de la Vaquita.

Through VaquitaCPR, conservation organizations such as Museo de la Ballena and the World Wildlife Fund are working with the Mexican Ministry of Environment and Mexican Navy as well as local fishermen to remove the illegal gillnets from the water on a continuing basis. This gear removal program is critical to the survival of the remaining vaquita.

“The seafood community has a long history of supporting the environmental and social needs of our community. None of these needs have been more important than the conservation, protection, and recovery needs of the vaquita porpoise,” said Lance Leonard, President/CEO of Ocean Garden Products, Inc. “The industry stands united in working with government, NGOs, and environmental groups to identify ways to save this unique mammal. We support the activity of VaquitaCPR and hope to bring attention to the cause with our customers and consumers.”

These companies, along with a number of other Mexican Seafood SR participants, have also sent a letter of support for alternative gear development to the Mexican government and upper Gulf of California shrimp fishermen. In this letter, they request that the Mexican government improve enforcement of the gillnet ban, but also expedite the processes necessary to develop and approve a viable alternative gear for small-scale shrimp fishermen.

“We would like to further express our willingness to collaborate in this important effort through the purchase, distribution, and marketing of the shrimp captures resulting from the adoption of fishing gears other than gillnets and or entanglement nets, which do not represent risk of bycatch to the vaquita marina,” participants wrote in the letter.

The importers are pledging future support to develop a market in the U.S. for “vaquita-safe” shrimp, once it becomes available. The letter was sent to the Secretary of Agriculture and Rural Development, Secretary of Environment and Natural Resources, National Commissioner of Aquaculture and Fisheries, and the National Commissioner of Natural Protected Areas, as well as shrimp producer cooperatives in the upper Gulf region.

According to Megan Westmeyer, SFP Senior Improvements and Strategy Manager, “When the permanent gillnet ban went into effect without a viable alternative gear for the artisanal shrimp fishery, the supply chain lost the ability to use its purchasing power to affect change. Fortunately, these suppliers are determined to see that the upper Gulf of California can be home to both the vaquita porpoise and a sustainable artisanal shrimp fishery, and are taking action to ensure this vision becomes reality.”

Appeals court blocks another US gov’t effort to overcome Mexico gillnet import ban

November 30, 2018 — The US Court of Appeals for the Federal Circuit on Wednesday shot down an effort by the US National Marine Fisheries Service (NMFS) and other federal agencies to end a four-month-old ban on the import of Mexican shrimp and other seafood caught in the country with the use of gillnets.

The decision to reject a “stay of the order” request backs a US Court of International Trade (CIT) ruling, issued in July, that was sought by the Natural Resources Defense Council (NRDC), Center for Biological Diversity and Animal Welfare Institute as part of an effort to protect the endangered vaquita porpoise in the northern Gulf of California from being driven into extinction by pressuring the Mexican government.

Widely decimated by the use of gillnets in pursuit of the totoaba — another endangered fish sought for its swim bladder due to black market demand in China — there are believed to be a little more than a dozen vaquita remaining.

To save the world’s rarest marine mammal, conservationists seek ban on Mexican seafood imports

July 12, 2018 — A decade of rescue crusades by conservation groups, hard-core eco-activists and the U.S. Navy have failed to prevent the world’s rarest porpoise from becoming fatally entangled in gill nets set for seafood in Mexico’s northern Gulf of California.

Now, with less than 20 vaquita left in the wild, the prospect of the species’ extinction within two years has prompted a last-ditch effort with significant economic and political consequences for the United States and Mexico.

Conservationists on Tuesday asked an international trade court judge in New York for a preliminary injunction banning imports of an estimated $16 million worth of fish and shrimp harvested with gill nets in an area of the gulf roughly a third the size of Los Angeles County and just three hours south of the border.

U.S. Court of International Trade Judge Gary Katzmann said he would rule within two weeks. His decision may hinge, in part, on whether the costs of implementing an embargo to save the species are greater than the costs of its disappearance.
