Fishing Boats ‘Going Dark’ Raise Suspicion Of Illegal Catches, Report Says

March 12, 2018 — A new report raises concerns that when fishing vessels “go dark” by switching off electronic tracking devices, in many cases they are doing so to mask the taking of illegal catches in protected marine parks and restricted national waters.

In the report released Monday by Oceana, an international conservation group, authors Lacey Malarky and Beth Lowell document incidents of fishing vessels that disappear from computer screens as they shut off collision-avoidance beacons near restricted areas, only to have them reappear days or weeks later back in legal fishing grounds.

“This practice of vessels going dark is really widespread on a global scale,” Malarky tells NPR.

Malarky and Lowell used Global Fishing Watch, which aggregates automatic identification system, or AIS, signals to give an unprecedented view of global fishing activity. AIS signals can be viewed by the public through such websites as Vesselfinder.com.

Yet another system, known as Vessel Management System, or VMS, is not available to the public but is used by countries to monitor their fishing fleets. However, “some countries can’t afford it — developing countries like those in West Africa,” Malarky says. “So, a lot of developing countries rely on AIS to monitor their fishing fleet.”

Can you hear me? NOAA studies boat noise and fish

January 8, 2018 — NOAA scientists studying sounds made by Atlantic cod and haddock at spawning sites in the Gulf of Maine have found that vessel traffic noise is reducing the distance over which these animals can communicate with each other.

As a result, daily behavior, feeding, mating, and socializing during critical biological periods for these commercially and ecologically important fish may be altered, according to a study published in Nature Scientific Reports.

Three sites in Massachusetts Bay included two inside Stellwagen Bank National Marine Sanctuary, a region well known to whale-watchers from the Cape because whales feed in the plankton-rich bank, and one inshore south of Cape Ann. All were monitored for three months by researchers at the Northeast Fisheries Science Center (NEFSC) laboratory in Woods Hole, and at the sanctuary offices in Scituate.

Vocalizations, such as Atlantic cod grunts and haddock knocks, were recorded by bottom-mounted instruments at each site during spawning in winter and spring.

“We looked at the hourly variation in ambient sound pressure levels and then estimated effective vocalization ranges at all three sites known to support spawning activity for Gulf of Maine cod and haddock stocks,” said Jenni Stanley, a marine research scientist in the passive acoustics group at the NEFSC and SBNMS and lead author of the study.

“Both fluctuated dramatically during the study. The sound levels appear to be largely driven by large vessel activity, and we found a signification positive correlation with the number of Automatic Identification System (AIS) tracked vessels at two of the three sites.”

AIS is an automatic tracking system, used on ships and by vessel traffic services. It provides information on a vessel, such as its unique identification number, position, course and speed, which can be displayed on a shipboard radar or electronic chart display.

Oceana claims four countries violated EU law by fishing illegally in African waters

September 14, 2017 — Environmental nonprofit Oceana is claiming vessels from the European Union’s distant-water fleet have been fishing unlawfully in the waters off the coasts of Equatorial Guinea and Gambia.

Using Automatic Identification System (AIS) data collected by satellite and terrestrial receivers tool Global Fishing Watch, Oceana said it tracked 19 vessels from Greece, Italy, Portugal, and Spain fishing unlawfully for more than 31,000 hours in African waters between April 2012 and August 2015.

The European Union has signed fisheries partnership agreements with several African countries, offering financial and technical support in exchange for fishing rights. However, its agreements with Gambia and Equatorial Guinea are “dormant,” signifying countries that signed fishing partnership agreements “without having a protocol into force, for structural or conjonctural reasons.” Under rules set by the European Commission, EU vessels are not allowed to fish in waters of countries with dormant agreements.

Satellite Tracking Spots Suspicious Activity from 12 Chinese Fishing Vessels in Peruvian Waters

October 17th, 2016 — At least a dozen Chinese vessels have illegally fished inside Peru’s national waters between January 2015 and September 2016, according to data analyzed by the satellite tracking platform Global Fishing Watch. This data suggests that over the course of the last year, Hong Pu5, Shung Feng 002 and several other vessels entered Peruvian waters at least once to fish in violation of international law.

Global Fishing Watch — a joint initiative of Oceana, SkyTruth and Google — uses navigation technology known as the Automatic Identification System (AIS) to track the movements of nearly 40,000 commercial fishing vessels around the world. AIS transmits a vessel’s identity, type, location, course and speed. Global Fishing Watch’s algorithm uses this information to identify fishing patterns, which helps fisheries officials and enforcement agencies spot potential criminal activity.

According to the UN’s Food and Agriculture Organization (FAO), illegal fishing in Peru is responsible for $360 million in losses each year. Peru is something of a “paradise” for pirate fishing, said Juan Carlos Sueiro, Oceana Peru’s fisheries director.

While neighbors Colombia, Chile and Ecuador have ratified a new FAO treaty aimed at curbing the trade in illegal fish in port cities, Peru has dragged its heels. As a result, Sueiro said, Chinese and other foreign vessels suspected of illegal fishing can freely dock, refuel, buy food and offload their catch in Peru.

New way to publicly monitor global fishing changes the game

September 16, 2016 — World leaders in ocean conservation and management are gathering in Washington this week for Secretary John Kerry‘s Our Ocean conference — a convening of global policymakers aimed a tackling some of the greatest challenges facing our seas and the wildlife that depend on them. I’m especially excited about this year’s meeting because it will mark the moment when we can truly begin a new era in fisheries management thanks to a groundbreaking new digital tool that will allow governments and citizens around the world to improve management to bring back fishery abundance and strengthen food security.

Early Thursday morning, we made Global Fishing Watch available to the public. Now for the first time ever, anyone with an internet connection can monitor global fishing activity, in near real-time, for free. Oceana partnered with SkyTruth and Google to produce a public platform that uses satellite data, cloud computing and machine learning to identify fishing activity all over the world and provide it to users in an intuitive internet-based interface.

Until today, the only way to really know what fishing vessels were doing was to have eyes physically trained on the ships, or to track vessels one at a time, point-by-point, day by day. That process is now automated by Global Fishing Watch so that anyone can instantly look at the tracks of tens of thousands of vessels, everywhere they fish, at any time over the past five years, within just a few days back from the present. This completely changes the game.

Ships over a certain size are required to use the Automatic Identification System (AIS) to avoid at-sea collisions. This broadcast data is collected by terrestrial and satellite receivers, and Global Fishing Watch analyzes it to locate apparent fishing activity. Now, for the first time, everyone can see where ships are fishing, and when. The applications of this technology to fishery policy and management are numerous. Early testers of Global Fishing Watch have consistently been bringing us new application ideas that even we, the developers, hadn’t imagined.
