Tracking the Chinese Squid Fleet in the South Pacific – Part 2: A City on the High Seas

Continued from Part 1: Voyage to the Galapagos.

As the Brigitte Bardot steamed west from the Galapagos we considered the sheer number of people we could expect to encounter when we reached this densely clustered fishing fleet 700 miles out to sea. The scale of fishing on the high seas has always been largely invisible to the seafood consuming public but our satellite tracking sources indicated an operation of truly remarkable size. From Automatic Identification System (AIS) data and radar we knew we were approaching a fleet of around 300 ships. These would be not only fishing vessels but a whole network of support vessels for refueling and transshipping catch from the fleet, as well as providing for an estimated 6,000 crewmen who would be at sea for several months at a time.

On the high seas in areas beyond national jurisdiction regulations are few and what oversight of fishing operations exists depends on Regional Fisheries Management Organizations (RFMOs). These RFMOs are established by international treaties to monitor and regulate fishing of particular species, although only some countries are signatories and there is a limited capacity for monitoring vast areas of open ocean. The region of the Eastern Pacific to which we were headed falls at the northern end of the area regulated by the South Pacific Regional Fisheries Management Organization (SPRFMO). The SPRFMO regulates fishing of non-tuna species and publishes a list of vessels authorized to fish in the area. However, beyond requiring countries to register their vessels and collecting the catch data they submit, no limits are set on squid catches.

We had our last sight of San Lorenzo Island the evening of September 19th and as we headed west into the open Pacific we expected a return of the rough weather we had seen on the voyage out. But by the next morning the seas were strangely still with fog obscuring our view much distance from the vessel. I sat below in the galley rechecking the latest set of AIS transmissions from the fleet against the SPRFMO’s authorization list. How a vessel is identified in the AIS system depends entirely on the information the vessel’s captain decides to input into his transmitter. Some operators conscientiously broadcast their full vessel name, callsign, International Maritime Organization (IMO) number, and flag. Others broadcast incomplete or outdated information via AIS and more than a few vessels give no identification at all or broadcast names that appear scrambled or don’t identify the vessel (“._NGDAYANG29” and “PS1” for instance). As a result, I had the challenge of trying to decipher as many of these vessel identifications as possible to determine if they were authorized to fish in the area.

In the afternoon I went up to the wheelhouse to stand watch. We continued through the fog, the Brigitte Bardot barely rocking on the calm seas. Jack, the Brigitte Bardot’s drone pilot taking a break from an action-packed stint on Sea Shepherd’s Milagro campaign in Mexico, explained the ship’s radar to me. We were limited in range by the relatively low height of the mast but our radar system had some useful options for locking and tracking targets and with a few adjustments we could even see the edge of an advancing rain front. But when Chris, the Brigitte Bardot‘s captain, joined us a few hours later there were still no blips on the radar screen. For the moment we appeared to have this vast stretch of the Pacific entirely to ourselves.

Despite the lack of vessels in the vicinity we expected to soon be reaching the edge of a huge fishing fleet and we needed to settle on a strategy. If there was illegal activity we would need to collect evidence before news of our arrival spread by radio through the fleet. I shared a list of potential targets with Chris and Jack. Unsatisfyingly all were ambiguous cases, vessels that didn’t give enough information in their AIS broadcasts for us to determine if they were SPRFMO authorized. We’d initially thought we’d have some clearly identified vessels that weren’t authorized to fish and had planned to arrive after nightfall (when squid fishing occurs) and collect evidence with a night vision camera. However with only ambiguous unidentified vessels as targets it made sense to arrive at the fleet during daylight hours when it would still be possible to easily read names and numbers painted on the vessel hull.

Chris called up the ship’s engineer Stefan. We could speed up to arrive at the fleet with a few hours of daylight but as Stefan explained this would be a trade-off with the extra fuel we burned ultimately limiting the ship’s range for this operation. After a brief discussion Stefan turned up the RPM on the Brigitte Bardot’s twin engines.

The calm weather continued through the next day as we sped west. Eloy, a Peruvian researcher who was finishing his thesis on tracking this fleet, sat out on deck reading through journal articles. If we had had any doubt that we were in squid fishing grounds this would have been dispelled by the dozens of squid which somehow made it onto the deck every night, when as Eloy explained, they rose to the surface to feed and possibly were attracted to the lights on the Brigitte Bardot. In fact this attraction to light is a critical part of squid fishing operations with the industrial fleet deploying lights on a massive scale to lure the squid in.

With the Brigitte Bardot’s crew gathered in the wheelhouse later in the afternoon there was a building sense of anticipation. The first vessel had appeared on the radar to the west an hour before and was quickly joined by half a dozen others. I checked these against satellite AIS, doing my best to guide the Brigitte Bardot towards a squid vessel broadcasting only the callsign BZZ5K, a callsign not registered to any vessel authorized to take squid. As we approached this first target Jack and Stefan passed back and forth a ridiculously large pair of pair of binoculars. Then on the port side the first vessel came into view.

Rust and soot on the hull seemed to obscure any identifying markings. Squid jigging gear projected out from either side below strings of giant bare bulbs hanging like oversized Christmas tree lights. A Chinese flag flew above the wheelhouse and at the stern of the vessel what appeared to be a tattered black sail. But on board all was quiet with a sea anchor keeping the vessel in place as the crew apparently waited below for the onset of nighttime fishing operations. This vessel was broadcasting AIS and we could faintly make out its name, which was on the SPRFMO authorization list, so we continued past it toward our target.

Reaching this first target, broadcasting callsign BZZ5K, was immediately anticlimactic. We could see a name and different callsign clearly painted on the hull, Hua Ying 819 with callsign BZV9K, an authorized vessel. The reason for the incorrect callsign on AIS was unclear but entirely legal since there are no regulations mandating correct identification on AIS. This is a frustrating situation for advocates of fisheries transparency since AIS is usually the only source of information the public has for tracking fleets out at sea. A simple requirement from flag states and authorities like the SPRFMO that vessels broadcasting AIS identify themselves correctly and broadcast continuously while operating, would dramatically improve the public’s ability to reliably monitor fleets on the high seas which are extracting a common global resource.

We sped on hoping to check a few more target vessels before dark. The fleet was now all around us, dozens of mostly still vessels extending out to the edge of radar reception. We’d expected that the arrival of the Brigitte Bardot would set off a flurry of chatter on the radio but the fleet was strangely silent as we set the radio to scan for broadcasts. We passed close to some vessels comparing their broadcast ID to identification painted on the hull and checking their authorization on the SPRFMO list. Once we noticed a few flashes of light through our wheelhouse’s starboard windows. Had someone tried to signal us with a mirror? Glancing back all seemed still on the boat we had passed.

We had soon spent the few hours of daylight we had gained by speeding westward. Though we’d managed to check off a number of the vessels with ambiguous AIS IDs on my target list we were finding that they all checked out once we were able to get identification from the vessel’s hull. As the sun sank below the horizon we halted to reassess the situation. So far just tracking down boats with bad AIS identification was not turning up any illegal activity. How about identifying vessels with no AIS broadcast at all? Consulting with Chris we decided to make a loose grid through the fleet checking the AIS broadcast of each boat as we approached.

The Brigitte Bardot now proceeded slowly to conserve fuel as we prepared to survey through the night. Suddenly out of the darkness a towering intense white light showed on the horizon. Soon it was followed by others all around us, mostly white but some an iridescent green and others with dimmer yellow light. Looking out from the wheelhouse we seemed no longer to be on the open ocean but in the edge of some great coastal metropolis.

The ships had now come alive. Squinting against the blinding lights we could see crewmen lined up behind the protruding jigging gear on either side of the vessel. Checking the AIS broadcasts of each vessel we were frustrated by what seemed to be severely limited reception range. Often we had to approach within a mile or two of a vessel before they appeared on our navigation plotter when it ought to have been possible to pick up vessels even 10 or 20 miles out. Around midnight when we judged the fishing operation to be well underway we roused Jack from below. It was time to take a closer look at what was actually happening on board these vessels.

Jack launched the drone, a phantom 4 quadcopter, from the bow of the Brigitte Bardot then stared intently at his control screen as he steered the drone in towards the fishing vessel. Navigating at night guided by only the vessel’s powerful fishing lights Jack brought the drone close over the deck avoiding the mast and cables strung high above the swaying vessel. Crewmen manned baited lines extending out from the ship in all directions. A few stopped and waved at the drone as it passed overhead. At one point the foreman on deck made an exasperated shooing motion with both hands. This fleet was on record for catching exclusively squid. Could something else be going on board? Large quantities of shark reached the coast of South America, mostly from longliners, with fins then shipped back to markets in China. Were sharks also caught on these vessels? Carefully examining the footage Jack would later notice a dozen fins protruding from the water around where the squid lines reached the ocean surface. But were these sharks being caught — or just hanging out where they might get some bait? The mechanics of landing a shark with the gear being used seemed difficult and on the vessels we could observe no sharks were seen on deck or on the fishing lines.

With the drone back on board we continued a slow survey through the fleet. Checking about 50 ships just one vessel we approached appeared not to be broadcasting AIS and all we identified had a valid authorization to fish. Eloy noted a clear distinction between vessels with strings of blinding LED lights (the total luminosity of these vessels is said to rival European soccer stadiums) and boats with somewhat dimmer yellow incandescent bulbs. We identified a number of vessels in these two categories so we could check later if this distinction also appeared in our data from NASA’s Visible Infrared Imaging Radiometer Suite (VIIRS). Hearing from Eloy that the satellite with the VIIRS instrument (NASA’s Soumi NPP) would be passing overhead at about 1:30 am, we also noted the positions of nearby vessels from the ship’s radar at precisely that time to compare with the vessel locations NOAA derived from the satellite’s imagery. I headed down for some sleep soon afterwards leaving the bridge in the hands of Simon, a professional photographer and veteran of Sea Shepherd’s Antarctic missions.

After getting a few inadequate hours of sleep I scrambled back up to the wheelhouse to look out at the fleet, now mostly quiet in the clear morning light. Jack and Chris were eager to show video captured the night before and as we looked at the latest satellite AIS data we could see one of the squid vessels alongside a reefer (refrigerated cargo ship). Was catch being transshipped just a few miles away? Today we would have a rare chance to document this activity and face a critical choice for continuing our investigation of fishing on the high seas.

New Milestones for Fisheries Transparency in Indonesia and Peru

Global Fishing Watch and SkyTruth team members at the Our Oceans conference in Bali, Indonesia.

Until recently public tracking of fishing activity has been almost entirely dependent on AIS (Automatic Identification System) data, an open system for vessel tracking and collision avoidance. It’s exciting to see this changing with the success of Global Fishing Watch’s Transparency Program. This program began when Indonesia’s fisheries minister Susi Pudjiastuti took the unprecedented step of sharing the country’s Vessel Monitoring System (VMS) tracking data publicly on Global Fishing Watch. VMS had traditionally been a closed monitoring system accessed only by government authorities. Public VMS made thousands of smaller Indonesian fishing vessels trackable in an region with little AIS coverage and established a new policy of total transparency to reinforce Minister Susi’s overhaul of a fisheries sector previously plagued by illegal fishing and labor abuses.

The Our Oceans conference last week in Bali, Indonesia was a chance to showcase the great work of our Indonesian team, recently including analysis of VIIRS (Visible Infrared Imaging Radiometer Suite) nighttime satellite imagery for detecting possible illegal activity in Indonesian waters and developing a process for validation of fishing effort predicted from VMS tracks along with Indonesian researchers. It’s also exciting to see that Indonesia has started a trend in choosing transparency in fisheries monitoring. Peruvian VMS tracking data now appears on the Global Fishing Watch map dramatically increasing our coverage of fishing in the eastern Pacific.

Here in Lima it has been great to see the Peru program take shape beginning with the commitment last year to publicly share VMS with Global Fishing Watch. Since then we have held workshops and training sessions with Peru’s Marine Research Institute and vessel monitoring authorities. I also recently had a chance to attend Peru’s biannual marine sciences conference (CONCIMAR) where along with Oceana Peru we put on a workshop for Peruvian students and announced the release of Peruvian data on the Global Fishing Watch map.

Both here in Peru and in Indonesia we are excited to see the beginning of a new era of transparency in monitoring and managing fishing resources. New tools and data sources developed by Global Fishing Watch and SkyTruth are being made available to local students, researchers, and government regulators. We are particularly pleased to see so much local interest from the countries that have chosen to share their tracking data publicly. And this is just the beginning. Global Fishing Watch has big plans for supporting fisheries transparency in the future as we aim to work with 20 countries in making their fishing fleets publicly trackable in the next five years.

Tracking the Chinese Squid Fleet in the South Pacific – Part 1: Voyage to the Galapagos

When monitoring vessel activity on the vast scale of the world’s oceans at SkyTruth we know we’re almost always dealing with incomplete information. For example, only some vessels transmit their locations at sea via the Automatic Identification System (AIS), while others may only come up in a particular government’s private Vessel Monitoring System (VMS) or we may just see them as blips on a radar screen. So I was excited to hear that I was invited to accompany a vessel actually going out to investigate one of the fleets we have been monitoring with AIS and night imagery. The ship I would board is the M/V Brigitte Bardot, a 35 meter former racing vessel now run by Sea Shepherd, an international non-profit dedicated to taking direct action for marine conservation. In 2016 Sea Shepherd was able to track down some unusual vessel activity that we spotted in the Indian Ocean with spectacular results.  This time we would be tracking a much larger fleet fishing for squid in international waters 700 miles west of the Galapagos.

Squid doesn’t come to mind when you consider the targets of the world’s largest fishing fleets. However, over the past few years the magnitude and global scale of squid fishing fleets have become apparent. Due to powerful fishing lights used to attract squid to the surface these fleets appear on NASA’s night imagery like cities floating hundreds of miles offshore. Recent analysis of vessel movements shows that they are interconnected with hundreds of predominantly Chinese flagged vessels moving between fleets along the Peruvian Exclusive Economic Zone (EEZ) boundary, the South Atlantic, the northwest Pacific, and even the northern Arabian Sea.

We’ve been monitoring the squid fleet fishing at the Peruvian EEZ boundary for some time. We noticed a handful of vessels in the fleet broadcasting false AIS locations. Then in 2017, we were puzzled when the entire fleet suddenly picked up and relocated 3,000 miles to the northwest of the EEZ boundary, to a remote area west of the Galapagos. So as I boarded Sea Shepherd’s Brigitte Bardot, I was really curious to find out the real size of the fleet and why so many vessels appeared concentrated at this remote location.

On September 12th, we set off from Panama City with some of us suffering from the rough seas as we steamed southwest towards the Galapagos. I was able to meet the very enthusiastic crew on the Brigitte Bardot, including a professional photographer, a drone pilot, and a fantastic vegan cook. We were also fortunate to be accompanied by Eloy Aroni, a Peruvian researcher who was just completing his thesis on tracking the squid fleet with nighttime satellite imagery from NASA’s Visible Infrared Imaging Radiometer Suite (VIIRS). After three days, we crossed into the Southern Hemisphere with the ship’s engineer taking a celebratory swim across the Equator. Later that afternoon, we sighted the desolate coast of San Cristobal Island, and after rounding the sheer rock cliffs of Sleeping Lion Rock, we entered the island’s main port.

We were held up in San Cristobal for a few days dealing with customs and inspections. This delay gave me a chance a to see bit of the island’s interior and review the latest information I had on the fleet we were tracking. Our data came from three sources, vessel AIS broadcasts, VIIRS night imagery, and interestingly two synthetic aperture radar (SAR) images of the fleet provided by Kongsberg Satellite Services (KSAT) as we were heading out. While SAR imagery is acquired routinely by the European Space Agency’s Sentinel-1 system over land and coastal areas it’s unusual to have imagery over the open ocean. So we were lucky to have access to a few shots of the fleet provided by KSAT from Canada’s Radarsat-2 satellite. This allowed us to make a comparison to our usual tracking sources for the fleet, AIS and VIIRS night imagery.

Those vessel detections outlined in green were found by KSAT to align closely with AIS broadcasts. Detections outlined in red could not be identified confidently with AIS. The inset on the lower right shows at larger scale the detection of the squid jigger Hsiang Man Ching. The large number of unidentified (red) detections was likely due to limited satellite AIS reception and does not necessarily indicate that the vessels were not broadcasting AIS.

AIS gives vessel locations and (usually) vessel identities. VIIRS gives us an approximate count of the number of vessels with their fishing lights lit up on a particular night. However, with no law requiring AIS use and the fact that VIIRS imagery is relatively low resolution (and still untested against this particular fleet), we suspected that these data sources might be giving us an incomplete picture of the total fleet activity. For these reasons, it was useful to make a comparison with the two SAR images since they should pick up every vessel present in the area, provided they are metal and above a certain size. Ultimately, comparison between the SAR vessel detections and total AIS broadcasts showed that despite a number of SAR vessel detections that could not be identified with AIS (outlined in red in the figure from KSAT above) the total number vessels detected by both systems was approximately the same, indicating high AIS use for the fleet, but also with a few clusters of radar detected vessels not associated with AIS.

After refueling on Baltra, a barren island with a former US military base, and installing a new satellite communications system, we set off on September 19th. In the evening we rounded the north cape of Santa Isabela Island and headed west into a vast stretch of the open Pacific. Ahead of us the nearest land was 3,000 nautical miles away in the Marquesas Islands of Polynesia. We would be venturing across some of the most remote surface of our planet on a voyage that would launch Operation Mamacocha, Sea Shepherd’s newest campaign fittingly named after the Incan sea goddess.

Global Fishing Watch Provides Training to Peru’s Vessel Surveillance Group

[Originally posted on the Global Fishing Watch blog, Aug. 15, 2018.]

We were very pleased to complete a three day training session this month in Lima with the Peruvian Ministry of Production’s vessel surveillance division. It was an opportunity for us to share the latest developments on the Global Fishing Watch mapping platform and to get expert feedback from professionals in Peru’s fisheries sector.

Since Peru’s public commitment in 2017 to show fishing activity from their Vessel Monitoring System (VMS) tracking data on our map we have engaged with local researchers and regulators to review and improve our data and analysis in the region. This began with a workshop with Peru’s Instituto del Mar de Peru (IMARPE) last December and now continues with Peruvian regulators directly responsible for daily monitoring of one of the world’s largest fisheries (Peruvian anchoveta).

In our most recent training session we highlighted the benefits of being able to view and compare multiple data sources on the Global Fishing Watch map including the new night lights and encounters layers launched in June this year. Many large fishing vessels on the Peruvian coast are covered both by AIS and the Peruvian VMS system. In training, we compared the tracking data from both systems for the same vessel showing how one system may cover a gap in the other.

The new night lights layer also has the potential to be very useful to regulators in combination with tracking data. A fleet of hundreds of Chinese vessels fishing for squid is expected to soon return to the Peruvian EEZ boundary. Individual fishing locations can be seen precisely due to the powerful lights they use to attract squid to the surface. However, to identify the fishing vessels, the night light information has to be combined with tracking and identity information from AIS. In training we identified a number of vessels in the Chinese squid fleet and followed their AIS tracks into port in Peru or to rendezvous with reefers (refrigerated cargo ships) where their catch is likely being transshipped.

As we work to develop new tools and data sources for the Global Fishing Watch map it’s valuable to get the insights of fisheries regulators on how they would like to be able to apply our map. So it was great to be able to wrap up the training with a discussion on features that it would be useful to enable in the future. These included being able to select an area on the map with the mouse and display a list of vessels inside and downloading reports of past activity for individual vessels as they come into port.

A special thanks to José Luis Herrera and Nilton Yarmas for coordinating the training. We also benefited greatly from the assistance of Eloy Aroni Sulca of Oceana’s Lima office who demonstrated many interesting potential applications of Global Fishing Watch in Peru. We look forward to hearing more in the future from participants in our training course and collaborating with them for successful monitoring and management of Peru’s ocean resources.
