March 11, 2021 — Global Fishing Watch data has shown a significant drop in fishing effort last year, apparently correlated to global COVID-19 lockdowns.
Founded in 2015, Global Fishing Watch is a partnership between Google and the advocacy groups Oceana and SkyTruth that collects vessel location data from satellite images and tracking systems.
December 22, 2020 — A tracking system designed to help ships avoid crashing into each other has become an important tool for spotting bad behavior on the high seas. Researchers can now put a spotlight on corporations that dominate fishing in unregulated international waters where it’s easier to get away with overfishing. And it’s giving us a better idea of how widespread slave labor could be on fishing vessels.
Two recently published papers use this technology, the maritime Automatic Identification System (AIS), to make high-seas fishing a little less mysterious. The first study, published in the journal One Earth on December 18th, traces the origins of thousands of high-seas fishing vessels back to big-time corporations that keep store shelves stocked with seafood. Other researchers use AIS to reveal telltale markers of forced labor on fishing boats, which were published today in the journal Proceedings of the National Academy of Sciences (PNAS). That all makes it easier to make companies answer for any abuses they commit at sea.
The technology, the maritime Automatic Identification System (AIS), has actually been around for about two decades. Basically, vessels carry around a box that sends out radio signals that anyone else can pick up on. Those radio signals share information about the ship, an identifying number, and other things like its size, course, and speed. That’s supposed to help vessels spot each other so they don’t get in each other’s way.
December 1, 2020 — On Aug. 5, 2017, China complied with a United Nations decision and formally imposed sanctions on North Korea, including a ban on seafood exports. Seafood, particularly squid, is one of North Korea’s few significant foreign-exchange earners, and the sanctions were expected to increase the pressure on the regime.
But just a few weeks after the ban came into effect, hundreds of squid-fishing vessels left Chinese waters and rounded the southern tip of South Korea. They entered North Korea’s 200 nautical-mile exclusive economic zone (EEZ), nearly doubling the number of Chinese fishing vessels operating there from 557 to 907, according a recent Global Fishing Watch report that tracked data from four different satellite systems. Even as China publicly claimed that is was complying with sanctions, many of the Chinese vessels continued to make trips to North Korea and back, including several round trips each year during both 2018 and 2019, said Jaeyoon Park, one of the report’s lead authors.
The Chinese fleet, made up of squid jiggers and pair trawlers, scooped up a staggering amount of squid—equal to almost as much as the entire squid catch in Japanese and South Korean waters combined over the same period, the report estimated. The Chinese decimated the squid population off North Korea to such a degree that Japanese and South Korean fishers saw their own take of the usually plentiful, migratory species plummet.
October 5, 2020 — In August, the world turned its attention towards the tiny Galápagos archipelago when nearly 300 Chinese-flagged vessels were found fishing near the Ecuadorian EEZ that encompasses the biologically-significant islands, raising concerns about illegal and unregulated fishing. A new report by environmental non-profit Oceana claims that the vessels, now moving south through Peru, may be purposefully turning off their satellite trackers to avoid detection.
Prompted to investigate by past illegal fishing in the same area in 2017, Oceana analyzed data from satellite transponders on the squid-fishing vessels over a one-month period to track vessel movements and map fishing activity.
Automatic Identification Systems
Automatic Identification Systems (AIS) on commercial vessels were originally used by ships to avoid collisions. A vessel’s identity, speed and location are automatically transmitted to satellite and terrestrial receivers at regular intervals. This publicly-available information is used by Global Fishing Watch, a public mapping tool developed by Oceana in collaboration with Google and SkyTruth, to visualize where vessels stop to fish, allowing for more scrutiny of potentially-illegal fishing activity.
July 30, 2020 — Global Fishing Watch has launched a public web portal to track the activity of at-sea transshipment, and has also signed an agreement with the government of Costa Rica to give it access to its vessel-tracking data.
Global Fishing Watch is a partnership between Google and the advocacy groups Oceana and SkyTruth founded in 2015. The new portal, hosted on Global Fishing Watch’s platform, aims to reveal the breadth of transshipment activity worldwide, with the goal of raising awareness among fish suppliers and consumers of the commonality of transshipment and improve transparency. The Pew Charitable Trusts contributed to the development of the portal to guide its effectiveness and application, according to Global Fishing Watch CEO Tony Long.
July 23, 2020 — Orbital observations have revealed extensive illegal fishing of Pacific flying squid (Todarodes pacificus) in the Pacific Ocean around Russia, Japan and North and South Korea in 2017 and 2018, a new study reports.
In fact, “extensive” may not be a strong enough word. More than 900 vessels of Chinese origin probably violated United Nations sanctions by fishing in North Korean waters in 2017, and another 700 did the same in 2018, the study found.
These scofflaw ships likely hauled in more than 176,000 tons (160,000 metric tons) of Pacific flying squid over those two years, a catch worth about US $440 million, study team members said. That’s nearly equivalent to the combined T. pacificus catch of Japan and South Korea over the same span.
“The scale of the fleet involved in this illegal fishing is about one-third the size of China’s entire distant-water fishing fleet,” said study co-lead author Jaeyoon Park, a senior data scientist at Global Fishing Watch, an international nonprofit organization dedicated to increasing ocean sustainability via greater transparency.
July 23, 2020 — Chinese “dark fleets” illegally fished a $440 million haul of the squid species Todarodes pacificus in North Korean waters during 2017 and 2018, according to a study published today in the journal Science Advances.
The study used a novel set of satellite images to track fishing vessels operating off the northeast coast of the Korean peninsula, including satellite synthetic aperture radar (SAR), visible infrared imaging radiometer suite sensors (VIIRS), high-resolution optical imagery, and identification beacon data from some of the vessels themselves. Its authors say that this is one of the first times those technologies have been combined to map illicit fishing at such a large scale over a years-long period.
“We believe that this study marks the beginning of a new era in fisheries management, transparency, and monitoring,” said Jaeyoon Park, senior data scientist at Global Fishing Watch and a co-lead author of the paper.
Park and his colleagues used data collected from Planet Labs, an Earth-imaging company that has also been instrumental in tracking deforestation caused by hard-to-track illegal gold mining, to map the movement of fishing boats in contested waters around the Korean peninsula. They found that in 2017, more than 900 Chinese fishing boats traveled to an area in North Korea’s exclusive economic zone, followed by another 700 in 2018.
July 22, 2020 — Oceana has released a new online tool that allows anyone to track ship speeds in speed zones designed to protect North Atlantic Right Whales along the east coast of the U.S. and Canada.
Using Global Fishing Watch data, which is a component of the new tool called Ship Speed Watch, Oceana Canada tracked ship speeds in the Cabot Strait from April 28 to June 15, 2020.
During the 49-day period, Transport Canada asked vessels longer than 13 meters to slow down to 10 knots.
Only a few complied, with 67 percent of the ships (464 out of 697) traveling faster than the 10-knot limit, and some traveling 20 knots or faster.
May 12, 2020 — Global commercial fishing activity for 2020 fell by around 1 million hours as of end-April, a 6.5% decline over the two previous years, the result of plummeting demand caused by coronavirus lockdowns, according to Global Fishing Watch.
Fishing fleets spent 14.4 million hours on the water for the year so far to April 28, a decline from an average of 15.4 million hours for the same year-to-date periods of 2018 and 2019, according to the nonprofit organization that tracks fishing operation worldwide.
Global Fishing Watch collects and analyses data from onboard identification systems known as AIS, which is used by large ships to broadcast their position and avoid collisions.
The closures of many hotels and restaurants – a large market sector for fisheries – and the logistical challenge of accessing necessary port services contributed to declining prices and plummeting demand, said Tyler Clavelle, a data scientist at Global Fishing Watch.
Much of the drop can be traced to China. While China’s industrial fleet started January more active than years past, there was a large drop after the Lunar New Year holiday in late January. For the two months to March 25, China’s fishing activities fell by 1.2 million hours, a 40% percent drop from the average for the same period the previous two years.
January 2, 2020 — In 2016, the Leonardo DiCaprio Foundation joined with Google, Oceana and Environmental Defense, and other funding partners to create a mapping and data platform called, Global Fishing Watch. The system currently tracks over 65,000 fishing vessels worldwide. In November 2019, the United Nation’s Food and Agriculture Organization (FAO) released the “Global Atlas of AIS-based Fishing Activity,” utilizing the data.
“With the data Global Fishing Watch provides, governments, fishery management organizations, researchers and the fishing industry can work together to rebuild fisheries and protect critical marine habitats,” De Caprio says, on the GFW website. It appears the FAO agrees.
Global Fishing Watch uses AIS and other tracking systems, such as government run vessels monitoring systems to follow the activities of large fishing vessels in near real time, and the UN is using that data in its report. At the start, the technology was intended to help nations to stop illegal fishing off their coasts, assist in certification of sustainably harvested seafood, and keep vessels out of marine protected areas.
