At least 6% of global fishing ‘probably illegal’ as ships turn off tracking devices

November 3, 2022 — Up to 6% of global fishing activity is hidden because commercial vessels disable their tracking systems, a practice that can be used to hide illegal fishing, according to a new study.

Ships use automatic identification systems (AIS), tracking beacons that enable them to be located on global shipping maps. Researchers applied a machine learning algorithm to a dataset of fishing vessel activity compiled by the non-profit Global Fishing Watch, which included more than 3.7bn AIS messages from fishing vessels between 2017 and 2019.

They discovered geographical hotspots for ships disabling their trackers, including west Africa, the coast of Argentina and the north-west Pacific – suggesting these are locations where illegal, unreported and unregulated (IUU) fishing is likely to be taking place.

Huffman, Graves get AIS provision included in Coast Guard bill

March 4, 2022 — Two U.S. representatives who have worked across the aisle to combat illegal fishing practices succeeded on Wednesday, 2 March, in amending a Coast Guard funding bill to include a requirement for more fishing vessels to install tracking systems.

U.S. Reps. Jared Huffman (D-California) and Garret Graves (R-Louisiana) say requiring boats that are at least 65 feet in length to have automatic identification systems (AIS) technology on board. A grant program that includes USD 5 million (EUR 4.5 million) would be made available to help boat owners purchase the equipment.

Scientists pen letter to Congress urging SIMP expansion

December 16, 2021 — More than 100 scientists signed a letter sent to Congress on Monday, 13 December, urging lawmakers to ensure that all seafood products imported into the United States are caught using legal means.

Illegal, unreported, and unregulated (IUU) fishing is often associated with human trafficking and other human rights abuses, and distant-water fishing forces vessel owners and operators to extend trips to “achieve a sizeable catch,” the university professors, research fellows, and scientists claimed in the two-page letter. In order to get that kind of catch, some operators will use forced labor and harvest fishing stocks beyond allowable limits, they alleged.

US Representative Jared Huffman defends AIS requirement in IUU bill that fishing industry finds redundant

September 30, 2021 — Nearly 130 members of the U.S. fishing industry signed a letter sent earlier this month to the top members of the U.S. House of Representatives subcommittee that oversees fishing policies, expressing concerns about a bill they said would create technological redundancies, add to their costs, and raise privacy concerns.

The industry members told U.S. Reps. Jared Huffman (D-California) and Cliff Bentz (R-Oregon), in the 14 September letter they oppose a proposed requirement in H.R. 3075, also known as the Illegal Fishing and Forced Labor Prevention Act, that would mandate automatic identification systems (AIS) be used to track fishing activities in both U.S. waters and the open seas.

129 Fishing Industry Representatives Ask Congress to Oppose ‘Duplicative’ New Vessel Monitoring Requirements

September 27, 2021 — 129 fishing industry representatives have written to Congress asking them to reconsider a bill that would require all fishing vessels to use Automatic Identification Systems (AIS) in U.S. waters and on the high seas, citing redundancy with other monitoring systems, cost and privacy concerns.

The letter, organized by the Saving Seafood Coalition and delivered to the House Subcommittee on Water, Oceans, and Wildlife, concerns H.R. 3075, the Illegal Fishing and Forced Labor Prevention Act. This legislation would require commercial fishing vessels to install AIS systems; however, most vessels already use Vessel Monitoring Systems (VMS) to track their locations. The letter notes several reasons why vessel operators prefer VMS to AIS, specifically privacy concerns associated with adopting AIS.

Current VMS hardware, unlike AIS, is based on secured end-to-end transmissions. AIS relies on VHF radio signals, which are susceptible to interception and risk being spoofed. Additionally, AIS data can be seen by other vessels and competitors, undermining privacy and data security that up until now has been an important part of NOAA’s vessel monitoring and data collection policies.

“We were concerned by the viewpoint expressed by Rep. Ed Case [D-HI], a

cosponsor of the bill, that no one ‘fishing in [United States] waters has an inherent right to privacy’ and that VMS data should not be considered proprietary,” the letter states. “That viewpoint is contrary to twenty-seven years of agency policy set forth by NOAA Administrative Order 216-100, which created a strict regime of controls to protect the privacy of data collected by the agency for purposes including the regulation and conservation of our fisheries.”

As noted in the letter, this position is shared by Janet Coit, who was recently confirmed as Assistant Administrator for NOAA Fisheries. In earlier written testimony, she stated:

“[Section 501 of H.R. 3075] is duplicative of existing Vessel Monitoring System (VMS) requirements since it would require those vessels already equipped with VMS to carry AIS without significant benefits. AIS is primarily a collision avoidance system, but VMS are more effective for tracking fishing vessel movement and effort, are less susceptible to tampering, and have better tools for two-way communications with vessels.”

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.

Satellite location data helps fight illegal fishing, even as vessels still evade detection

April 12, 2018 — At least every 30 seconds, more than 70,000 fishing vessels responsible for most of the world’s catch broadcast automatic identification systems (AIS) signaling their identity, location, and speed.

The AIS systems were originally designed to help large vessels avoid collisions on the open ocean, but in recent years, conservation groups and fisheries enforcement have used those signals for a new purpose: spotting vessels that might be fishing illegally.

But this technique is far from watertight. Oceana, a conservation group, has documented millions of instances since 2012 of vessels going dark by turning off public trackers.

“Vessels disabling their public tracker is a common occurrence and is happening in all corners of the world — we are just now beginning to understand how widespread the practice is,” Beth Lowell, senior campaign director for illegal fishing and seafood fraud at Oceana, told SeafoodSource.

Vessels might turn off tracking for multiple reasons, many of them legitimate, such as evading pirates. But when a vessel turns off location broadcasting near marine reserves and other areas where fishing is limited or illegal, it raises questions, Lowell said.

For instance, Oceana documented a Panamanian vessel on the west side of the Galapagos Marine Reserve that seemed to disappear for 15 days before reappearing on the east side. Meanwhile, an Australian vessel’s AIS signals were shut off near Heard Island and the McDonald Islands Marine Reserve 10 times in one year, and a Spanish vessel went dark near The Gambia’s national waters repeatedly.

Ray Hilborn: New study provides no new information on global fishing footprint

March 7, 2018 — University of Washington fisheries researcher Ray Hilborn said that a new study using satellite data from industrial fishing vessels to map global fishing effort fails to provide any new insight, despite media reports indicating otherwise.

The study, published in Science in February, used messages transmitted between 2012 and 2016 from the automatic identification systems (AIS) of more than 70,000 industrial fishing vessels to create a global footprint, concluding that “industrial fishing occurs in over 55 percent of ocean area,” according to the abstract.

But Hilborn said the vessels monitored for the study were in large part tuna boats over 100 feet, which have been monitored for decades.

“Most of the footprint data they have is from high-seas tuna fishing, because that’s really the only thing that goes on on the high seas. Maps of the tuna long-lining and seining distribution have been distributed as part of the standard operating procedure by the tuna RFMOs [regional fisheries management organizations] for decades. I remember looking at them 30 or 40 years ago. There’s nothing new about this – that tuna fishing goes on across much of tropical oceans and some of the temperate oceans,” Hilborn told SeafoodSource.

Not only is this not new information, Hilborn said, but it does little to measure the impact of trawling on certain ecosystems, which Hilborn said can be much more severe than high-seas fishing.

“A place that has had one long-line for albacore or big-eye tuna in five years is obviously not very heavily fished, he said. “But if you go to Southeast Asia, we can calculate how often the average piece of bottom is trawled a year. In the U.S., depending on where, it’s about once every three years. In Southeast Asia or India, they are trawled 10 to 20 times a year. That means the impact of fishing there is probably 1,000 times higher than it is on the high seas where someone once visited with a long-line boat.”

Furthermore, the trawling data provided in the new study, Hilborn said, overestimates the proportion of the sea-bed that is affected by 10 times. Hilborn and his team have just completed a five-year study that attempts to provide a finer-grained look at the impact of trawling by aggregating data from vessel-monitoring systems, logbooks, and on-board observations.

Media Fails Again on Fisheries Data; New Maps Don’t Show Intensification of Fishing – Hilborn

February 26, 2018 — SEAFOOD NEWS — The lead article in Science this week, picked up in numerous publications, highlighted data from the AIS vessel tracking system to show the global impact of industrial fishing.

The authors state that vessels are now fishing in 55% of the world’s oceans, which is an area four times larger than occupied by onshore agriculture.

The immediate popular conclusion was that this shows immense overfishing, and Oceana was quoted saying “That means we’re putting more pressure on fish populations.”

But that is not what the data show.  As pointed out consistently by Professor Ray Hilborn of the University of Washington, the comparison with agriculture is simply wrong.

Hilborn says “The comparison to agriculture fails to note that the 50 million square kilometers under agriculture have destroyed the natural ecosystem as the plow or new pasture eliminates the native plants.   The areas fished, particularly for tunas, have changed very little.”

Furthermore,  “Fishing does not impact the primary production (plants), and in very few cases does it impact the species that graze on the primary producers.  So the 50 million square kilometers of the earths’ surface that is used for agriculture is totally transformed,  most of the oceans that are being fished (high seas tuna)  have some changes in top predators abundance. “

Hilborn points out that “High seas fishing for tuna, which constitutes the majority of the “footprint” shown in the Science paper has been mapped for 40 years, and the widespread nature of high seas tuna fishing is well known.  The footprint of bottom trawlers has been mapped in much finer scale already in many places, and the Science paper overestimates the proportion of the seabed impacted by trawls by 10 fold.”

The AIS data is interesting, and allows for specific types of research that was not possible before.  However, the dataset does not give as accurate a picture of global fishing as does the comprehensive database on fish stock surveys and catch records.

Hilborn says “For most of the areas where there are data in this study,  fish stocks are actually increasing and tuna populations are well documented and globally stable.”

Hilborn is a longtime collaborator with Dr. Boris Worm, one of the authors of the paper.  Together they did a groundbreaking study of global fisheries databases, and helped create a standard dataset to measure fisheries catches and stock health.  Neither Worm nor the other authors are claiming that the AIS study shows increased fishing pressure on stocks, they are simply reporting that the tracking data provides a new visualization tool for global fisheries.
