New research partnership formed to investigate illegal fishing in North Pacific

September 17, 2018 — Japan’s Fisheries Research and Education Agency (FRA) will help Global Fishing Watch and the Australian National Center for Ocean Resources and Security (ANCORS) at the University of Wollongong, in New South Wales, with their investigation of illegal, unreported and unregulated (IUU) fishing.

Following a memorandum of understanding signed on Sept. 3, the groups have agreed to share “relevant open public data and analytical methodologies, including vessel movement data, catch data and satellite imagery; collaborate on relevant research activities, and publish research outcomes to advance international understanding on IUU fishing and its impacts,” according to a press release.

They intend to analyze night-time satellite imagery, the groups say, as squid jigging most often takes place at night, using bright overhead lights to attract the squid.

Is a Splashy Fishing Statistic Misleading?

September 10, 2018 — How much of the world’s oceans are affected by fishing? In February, a team of scientists led by David Kroodsma from the Global Fishing Watch published a paper that put the figure at 55 percent—an area four times larger than that covered by land-based agriculture. The paper was widely covered, with several outlets leading with the eye-popping stat that “half the world’s oceans [are] now fished industrially.”

Ricardo Amoroso from the University of Washington had also been trying to track global fishing activity and when he saw the headlines, he felt that the 55 percent figure was wildly off. He and his colleagues re-analyzed the data that the Global Fishing Watch had made freely available. And in their own paper, published two weeks ago, they claim that industrial fishing occurs over just 4 percent of the ocean.

How could two groups have produced such wildly different answers using the same set of data? At its core, this is a simple academic disagreement about scale. But it’s also a more subtle debate that hinges on how we think about the act of fishing, and how to measure humanity’s influence on the planet. “I think this discussion really shows how little we know about the world’s oceans and why making data publicly available is so important for stimulating research,” says Kroodsma.

As ships traverse the oceans, many of them continuously transmit their position, speed, and identity to satellites. This automatic identification system was originally developed to prevent collisions, but by training Google’s machine-learning tools on the data, the Global Fishing Watch (GFW)—an initiative led by the nonprofits Oceana and SkyTruth—can identify different kinds of fishing vessels, and work out where they’re dropping their lines and nets.

What is the Global Footprint of Fishing?

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.

Global Fishing Watch launched in 2016 as a way to track fishing boats around the world. The core data comes from boats’ automatic identification system (AIS), a GPS system that pings out its location every 30 seconds to satellites. Most large boats around the world (not just fishing boats) are required to have AIS onboard for monitoring purposes and safety. Global Fishing Watch collects AIS data on all boats around the world to “determine the type of ship (e.g., cargo, tug, sail, fishing), its size, what kind of fishing gear (e.g. longline, purse seine, trawl) it’s using, and where and when it’s fishing based on its movement patterns.” It is an impressive way to collect fishing data and shows some promise for curbing illegal fishing. You can read more about it here.

One of the first major publications to come out of these AIS data attempted to map the ‘global footprint’ of fishing. It concluded that 55% of the global ocean was fished. However a recent paper, using the exact same data, concluded that only 4% of the global ocean is fished. An order of magnitude difference! What is going on here?

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  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.
