September 5, 2018 — Thanks to Global Fishing Watch, a new partnership between Oceana, SkyAtlas, and Google, scientists may be getting closer to figuring out how much of the world’s ocean is fished—but discrepancies in the scale of data are producing wildly different answers.
Models may help reduce bycatch from longline fishing
August 10, 2018 — Hundreds of thousands of sharks, sea birds and other marine species are accidentally killed each year after they become snagged or entangled in longline fishing gear.
New models developed by a Duke University-led team may help reduce this threat by giving regulatory agencies a powerful new tool to predict the month-by-month movements of longline fishing fleets on the high seas. The predictions should help determine where and when the boats will enter waters where by-catch risks are greatest.
“By comparing our models with data showing where by-catch species are likely to be each month, ship captains, national agencies and regional fisheries management organizations can pinpoint potential hotspots they may want to temporarily avoid or place off-limits,” said Guillermo Ortuño Crespo, a doctoral candidate in the Marine Geospatial Ecology Lab at Duke’s Nicholas School of the Environment.
“This represents a movement away from a reactive approach to fisheries management — where we only know about problems as or after they occur — to a more proactive approach that helps us stay one step ahead of the game,” he said.
Ortuño Crespo and his colleagues describe their new models in a peer-reviewed paper August 8 in Science Advances.
To devise the models, they collaborated with Global Fishing Watch to collect geospatial information from individual boats’ automatic identification system (AIS) signals. AIS data shows the movements and distribution of longline fishing fleets operating in the high seas in 2015 and 2016.
Then they statistically correlated each ship’s fishing efforts to 14 environmental variables — such as sea surface temperatures or distance to the nearest seamount — that influence a region’s seasonal suitability as a habitat for species targeted by longliners. This allowed them to create highly accurate models that predict where the fishing fleets will be each month of the year.
The new models track data for fleets from Japan, South Korea, Taiwan, China and Spain, which accounts for most of the longline fishing currently taking place in the open ocean beyond national jurisdictions. Future models could include fleets from other nations and offer expanded functionality that will allow regulatory agencies to view the data within a global context or break it down by individual nation, region or fleet.
Researchers map hot spots of transfer of fish catch at sea
July 26, 2018 — It could be considered the global CSI for high seas fisheries. In two new groundbreaking studies, researchers from Dalhousie University, Global Fishing Watch and SkyTruth have applied cutting-edge technology to map exactly where fishing boats may be transferring their catch to cargo vessels at sea.
Known as transshipment, the practice increases the efficiency of fishing by eliminating trips back to port for fishing vessels. However, as it often occurs out of sight and over the horizon, it creates major challenges, including enabling illegal, unreported and unregulated (IUU) fishing.
“Because catches from different boats are mixed up during transshipment, we often have no idea what was caught legally and what wasn’t,” said Kristina Boerder, a Ph.D. student in Dalhousie University’s Department of Biology and lead author on the Science Advances paper, published this week.
Transshipment can also facilitate human rights abuses and has been implicated in other crimes such as weapons and drug trafficking. It often occurs in the high seas, beyond the reach of any nation’s jurisdiction, and where policy-makers and enforcement agencies may be slow to act against an issue they cannot see. By applying machine learning techniques to vessel tracking data, researchers are bringing unprecedented transparency to the practice.
“So far, this practise was out of sight out of mind, but now that we can track it using satellites, we can begin to know where our fish truly comes from,” says Dr. Boris Worm, a Marine Biology Professor in Dalhousie’s Faculty of Science, and co-author of the Science Advances paper.

Oceana report claims Italy ignoring IUU
July 13, 2018 — Oceana released a report on 12 July that suggests multiple European governments, particularly Italy, are turning a blind eye to illegal, unreported, and unregulated (IUU) fishing in the Mediterranean Sea.
The report, which used data from Automatic Identification Systems (AIS) tracking from Global Fishing Watch (GFW), found suspected cases of bottom trawlers operating in Fisheries Restricted Areas (FRA) and foreign vessels active in waters that potentially qualify as IUU. The biggest offender, Italy, was found to have more than 10,000 hours of illegal fishing activity from Italian-flagged bottom trawler-equipped vessels in the FRA established in the Strait of Sicily.
The area in the Strait of Sicily is designed to protect young hake populations where the stock is already overfished. Trawling in the area is prohibited.
The IUU vessels were discovered using GFW’s fishing detection algorithms. According to Oceana, the actual amount of IUU may be even higher, as some vessels could have either “lacked AIS equipment or have turned off AIS broadcasting.”
The findings were discussed at two governmental meetings of the General Fisheries Commission for the Mediterranean. According to Oceana, the countries “failed to provide clarification on whether any vessel has been fined or if any punishable action will be taken” during that meeting.
“While Mediterranean governments and their leaders are committing globally to fight pirate fishing under the UN Sustainable Development Goals, the very same governments are turning a blind eye to potential cases in their own Mediterranean Sea,” said Lasse Gustavsson, executive director of Oceana Europe. “Information gathered by Oceana indicates that fishing vessels that can easily be identified are blatantly violating the law in fisheries-restricted areas. They’re doing nothing to uphold the law.”
IUU vessel tracker calls on more countries to share Indonesia’s lead, share data
June 22, 2018 — Indonesia is a model that other countries should follow, according to a leading campaigner advocating for the sharing of fishing data to reduce illegal, unreported and unregulated (IUU) fishing.
By making its vessel monitoring system (VMS) data publicly available, the country has increased transparency, said Tony Long, CEO of Global Fishing Watch, who was speaking at the 2018 SeaWeb Seafood Summit. The Indonesian fisheries ministry, which has been battling illegal fishing in its waters, moved to share its VMS data in 2017.
Not enough countries exchange data, said Long, who wants countries to “bring data out into the open” so that vessels’ movements can be tracked and illegal fishing operators exposed. “Global Fishing Watch will take and share any tracking system,” he said.
More transparency is key to forcing vessel operators into more responsible behavior, argued Long.
“Why not reward the compliant operators when you can track them?” he said. “The worst actors will stand out by their lack of information and therefore appropriate punishments can be put in place.”
Global Fishing Watch leverages tracking systems like Oceana, Skytruth and Google as well as national systems to map global movement of vessels.
Long’s organization has also recently partnered with the US National Oceanic & Atmospheric Administration (NOAA) to track vessels using satellites the monitor lights at night. A screen grab from one such monitoring off the coast of Oman showed that AIS data is underreporting the number of vessels in the waters: The data based on the number of lights in the night sky suggested a far larger fleet at work.
The ‘dark fleet’: Global Fishing Watch shines a light on illegal catches
June 11, 2018 — New data is being used to expose fleets of previously unmonitored fishing vessels on the high seas, in what campaigners hope will lead to the eradication of illegal, unregulated and unreported fishing.
Global Fishing Watch (GFW) has turned low light imaging data collected by the US National Oceanic and Atmospheric Administration (NOAA) into the first publicly available real-time map showing the location and identity of thousands of vessels operating at night in waters that lie beyond national jurisdiction.
More than 85% of the “dark fleet” detections include smaller vessels that are not fitted with transponders and larger ones that have switched off their tracking systems to avoid detection, according to GFW, which launched the map on Friday to mark World Oceans Day.
The data, collected by the NOAA’s visible infrared imaging radiometer suite, is being used to track a fleet of about 200 mostly Chinese vessels at the edge of Peru’s economic exclusion zone.
The monitoring, conducted by GFW, a non-profit organisation campaigning for greater transparency in the fishing industry, and the conservation group Oceana, reveals that about 20% of the Chinese vessels are not broadcasting via automatic tracking systems, raising suspicions they are operating illegally.
The report on the high seas activity coincides with the launch by GFW of the first ever real-time view of transshipment, which enables fishing boats to transfer their catch to refrigerated cargo vessels and remain at sea for months, or even years, at a time but still get their catch to the market.
Study on economics of fishing on the high seas
June 7, 2018 — As much as 54 percent of the high seas fishing industry would be unprofitable at its current scale without large government subsidies, according to a new study by researchers from the National Geographic Society; the University of California, Santa Barbara; Global Fishing Watch; the Sea Around Us project at the University of British Columbia; and the University of Western Australia. The research, published today in the open-access journal Science Advances, found that the global cost of fishing in the high seas ranged between $6.2 billion and $8 billion USD in 2014. Profits from this activity range between a loss of $364 million and a profit of $1.4 billion USD.
The high seas—marine waters beyond national jurisdiction—cover 64 percent of the ocean’s surface and are dominated by a small number of fishing countries, which reap most of the benefits of fishing this internationally shared area. While the environmental impacts of fishing on the high seas are well studied, a high level of secrecy around distant-water fishing had previously precluded reliable estimates of the economic costs and benefits of high seas fishing. However, newly compiled satellite data and machine learning have revealed a far more accurate picture of fishing effort across the globe at the level of individual vessels.
“The reason most fleets continue to operate in the high seas is that they receive government subsidies. Without subsidies and the forced labor some of them are known for, fishing would be unprofitable in over half of the high seas fishing grounds,” said Enric Sala, National Geographic Explorer-in-Residence and lead author of the study.
Using Automatic Identification Systems (AIS) and Vessel Monitoring Systems (VMS), the researchers were able to track the individual behavior, fishing activity and other characteristics of 3,620 vessels in near-real time. Combining this information with the global catch data from the University of British Columbia’s Sea Around Us project, the team was then able to determine how much effort the vessels expended, how large their catch was, and how much profit the catch generated.
Global Fishing Watch and Costa Rica sign agreement
May 18, 2018 — Global Fishing Watch, a transparency platform established by Google, Oceana, and Skytruth to map the location of all commercial fishing vessels anywhere in the world, has just signed an agreement with Costa Rica.
The agreement between the Costa Rican government and Global Fishing Watch (GFW) provides for mapping and analysis of activities at sea and fishing activities in the country’s Exclusive Economic Zone, a report in El Nuevo Diario said.
“The collaboration agreement with Global Fishing Watch is a step forward in strengthening the capabilities of our ministry for effective protection of fishery resources and surveillance of our maritime territory through state-of-the-art technology,” Gustavo Mata, the minister of public security said in a statement.

Global Fishing Watch responds to Ray Hilborn’s critiques of its study
March 27, 2018 — Global Fishing Watch welcomes Dr. Ray Hilborn’s recent statement in Seafood Source expressing his desire to work together to strengthen our collective insights into commercial fishing activity.
Furthering innovation and collaboration with the scientific community is at the heart of Global Fishing Watch’s mission to advance responsible stewardship of our oceans through increased transparency. Our Research Partners program, an interdisciplinary collaboration with some of the world’s leading marine science institutes, strives to improve fisheries management and science through the sharing of data, new research and cooperation.
Our recent study published in Science was produced with partners at the University of California, University of Santa Barbara, National Geographic Society’s Pristine Seas project, SkyTruth, Dalhousie University, Stanford University, and Google. This research has produced the first-ever dataset of global fishing activities, as captured by satellites using automatic identification system (AIS) positions. Global Fishing Watch’s algorithm processed 22 billion AIS messages to identify more than 70,000 commercial fishing vessels, the sizes of and engine powers of these vessels, what type of fishing they engaged in, and where and when they fished down to the hour and kilometer.
The study and associated maps also depict global fishing activity with an unprecedented resolution – the fishing effort footprint is two to three orders of magnitude higher in spatial and temporal resolution than previous datasets – and reveals that industrial fishing covers more than 55 percent of the ocean’s surface – over four times the area covered by agriculture. This new high-definition global view of fishing would not have been possible without recent advances in computing power, an increase of satellites in orbit, and improved machine learning algorithms.
Importantly, by making all of the data in this study public and freely available, we aim to increase transparency in the commercial fishing industry and improve opportunities for sustainable management and informed decision making. We have also grown the data available within our transparency platform, including adding more AIS data, and through our government and research partners, including vessel monitoring system (VMS) and Visible Infrared Imaging Radiometer Suite (VIIRS) data.
Dr. Hilborn says that vessels monitored for the study were largely tuna boats over 100 feet in length. Technically, these tuna boats are only a fraction of the 70,000 vessels monitored in our study. By far, the vast majority of vessels we observe are Chinese vessels operating in Chinese waters.
For the study, we also only track vessels that have AIS devices, and the fraction of fishing vessels with AIS varies considerably between regions of the ocean. In some regions, such as in Europe, almost all sizeable fishing vessels broadcast their locations. Similarly, in the high seas, we can capture most of the fishing activity, as a high fraction of high seas fishing vessels carry AIS. By contrast, in many developing countries, only a small number do. This fact makes our dataset incomplete, but it is still far more comprehensive than previous global datasets of fishing effort.

Shark bill could resolve debate over domestic fin market
March 20, 2018 — It’s fair to say that if the press release is coming from Oceana, it’s not going to have anything nice to say about the fishing industry. This is an outfit that seems to glory in perpetuating the misconception that reports on global fisheries apply equally to U.S. fishermen, fleets and practices as they do to foreign industry players.
That’s why when I saw Oceana had collaborated in the launch of Global Fishing Watch, I knew something outside of the worthy mission of combating IUU fishing was likely to come of it. We saw that in late February with the release of an article in Science that based its data on Global Fishing Watch.
Granted, if you look at the maps of aggregate data, you’ll see that U.S. coastal waters are not covered with the traffic Oceana deems damning. But not many average readers have time to dig that far or ask these kinds of questions about data sets. They see the headlines and condemn all fishing en masse.
The misconception that our fishing industry is just a small part of a globally mismanaged fishing industry is a perpetual grind against our highly regulated U.S. fleets.
Fishing is the seventh most regulated industry in the country, just barely outranking fishing is commercial air travel. And right behind it? Oil and gas extraction.
“I fish in North Carolina, and I’m regulated by the South Atlantic council, the Mid-Atlantic council, NMFS, the Atlantic States [Marine Fisheries Commission] and the state of North Carolina,” said Dewey Hemilright, a 2012 NF Highliner from Wanchese, N.C., and a supporter of a new bill that would preserve U.S. shark fishing.
The Sustainable Shark Fisheries and Trade Act of 2018 (H.R. 524) is a bipartisan bill that aims to create a formal and transparent certification program for countries seeking to import shark products into the United States. Foreign nations would apply for certification from the U.S. Secretary of Commerce confirming that they have an effective prohibition on shark finning and have shark management policies comparable to ours.
