Saving Seafood

The information age is starting to transform fishing worldwide

April 14, 2022 — People in the world’s developed nations live in a post-industrial era, working mainly in service or knowledge industries. Manufacturers increasingly rely on sensors, robots, artificial intelligence and machine learning to replace human labor or make it more efficient. Farmers can monitor crop health via satellite and apply pesticides and fertilizers with drones.

Commercial fishing, one of the oldest industries in the world, is a stark exception. Industrial fishing, with factory ships and deep-sea trawlers that land thousands of tons of fish at a time, are still the dominant hunting mode in much of the world.

Fishing with data

Changes in behavior, technology and policy are occurring throughout the fishing industry. Here are some examples:

  • Global Fishing Watch, an international nonprofit, monitors and creates open-access visualizations of global fishing activity on the internet with a 72-hour delay. This transparency breakthrough has led to the arrest and conviction of owners and captains of boats fishing illegally.
  • The Global Dialogue on Seafood Traceability, an international business-to-business initiative, creates voluntary industry standards for seafood traceability. These standards are designed to help harmonize various systems that track seafood through the supply chain, so they all collect the same key information and rely on the same data sources. This information lets buyers know where their seafood comes from and whether it was produced sustainably.
  • Fishing boats in New Bedford, Massachusetts – the top U.S. fishing port, based on total catch value – are rigged with sensors to develop a Marine Data Bank that will give fishermen data on ocean temperature, salinity and oxygen levels. Linking this data to actual stock behavior and catch levels is expected to help fishermen target certain species and avoid unintentional bycatch.

The ocean’s restorative power

There is no shortage of gloomy information about how overfishing, along with other stresses like climate change, is affecting the world’s oceans. Nonetheless, I believe it bears emphasizing that over 78% of current marine fish landings come from biologically sustainable stocks, according to the United Nations. And overharvested fisheries often can rebound with smart management.

For example, the U.S. east coast scallop fishery, which was essentially defunct in the mid-1990s, is now a sustainable US$570 million a year industry.

FAO, NGOs push for guidelines on transshipment

January 31, 2022 — A campaign to develop, publicize, and enforce guidelines setting standards for the responsible management of transferring catch between vessels at sea is gaining momentum.

The Food and Agriculture Organization is leading an effort to close loopholes allowing for transshipment of catch on the high seas, a practice the United Nations organization said encourages illegal, unreported, and unregulated (IUU) fishing.

IUU vessel-tracker shows possible widespread abuse of AIS switch-off capability

June 22, 2021 — A newly launched map of the locations of fishing vessels involved in illegal, unreported, and unregulated (IUU) fishing has one big problem: there’s not much to show.

The new tool, the IUU Vessel Tracker, was launched Wednesday, 16 June, by non-governmental organization Oceana. It uses Global Fishing Watch tracking data cross-indexed with a list of vessels linked to IUU compiled by regional fishery management organizations and Norway-based nonprofit Trygg Mat Tracking. But Oceana said the tool, which allows anyone in the world to track the activities of these vessels in near real-time, is currently tracking just two of 168 vessels on the list. The two vessels visible, the Phoenix and the Nadhodka, are flagged to the Seychelles and Russia, respectively.

Oceana reports Chinese, Spanish squid vessels ‘going dark’ off Argentina

June 4, 2021 — A South Atlantic shortfin squid fishery is dominated by distant-water fleets off Argentina, primarily Chinese vessels that account for an estimated 69 percent of fishing activity, according to a new report by the environmental group Oceana.

From Jan. 1, 2018 to April 25, 2021, the group documented more than 800 foreign-flag vessels logging more than 900,000 hours of apparent fishing activity, based on analysis of Automatic Identification System (AIS) data.

That analysis also showed vessels regularly “went dark” – apparently turning off their AIS transponders – effectively dropping out of sight for 600,000 hours in all. Some 66 percent of those outages involved Chinese vessels, raising the possibility of masked illegal fishing, such as intruding into Argentina’s exclusive economic zone, according to Oceana researchers.

Global Fishing Watch opens doors on new MPA management portal, transshipment data

May 27, 2021 — Global Fishing Watch, an international nonprofit organization dedicated to advancing the sustainability of our ocean through increased transparency of human activity at sea, is seeking to improve science-based management of marine protected areas with a new digital tool aiming to “revolutionize [the] ability to dynamically monitor and conserve marine ecosystems.”

On 27 May, it formally launched its Global Fishing Watch Marine Manager, a technology portal that will allow regulatory authorities and researchers to monitor vessels involved in commercial fishing and other activities, such as vessels involved in tourism, oil drilling, and shipping. Vessel information can be overlaid with other datasets in the portal, including environmental such as salinity and sea surface temperatures, according to Global Fishing Watch CEO Tony Long.

Slavery and overfishing on the high seas can’t hide from these researchers

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.

China’s Monster Fishing Fleet

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.

New Oceana Report Suggests Shady Fishing Practices By Large Fleet Near Galápagos

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.
