86,490 Points on a Map: All Potential Transshipments

5 years of transshipments 86 billionOn February 22, we announced some remarkable new insights about what goes on between fishing vessels at sea. The artificial intelligence platform we developed found that over the past five years, there were more than 86,000 potential cases in which fishing vessels transferred their catch to refrigerated cargo ships at sea. The practice is called transshipment, and in many cases it is illegal because it enables the mixing of legal and illegal catch and facilitates slave labor on fishing vessels that don’t need to return to port to drop off their catch.

Deciphering Suspicious Behavior: Not Always What It Seems

The first step in catching illegal and unreported fishing activity can feel a little like casting a net over a wide swath of the ocean. There’s going to be a lot of bycatch, because much of what fits in your net isn’t really what you’re after. It takes some background knowledge and often a little investigative work to find the keepers. Sometimes you come up empty handed.

Here are some reasons suspicious-looking behavior by commercial fishing vessels might actually represent perfectly legal activity. Read more

Fishing Fleet Goes Home for the Holidays

‘Tis the season, and even fishers want to be home for the holidays. The flag state filter in Global Fishing Watch allows us to select vessels flagged to a specific country or countries. In the spirit of the season, we decided to use it to see if  a cultural tradition that has nothing to do with fishing can be revealed through fishing vessel behavior. Watch the video to see what we mean, then check it out for yourself by following the links below to the same work space on the Global Fishing Watch map.

Taming the Ocean’s Wild West

The high seas are often called the ocean’s Wild West—open territory far from any shoreline or national jurisdiction where the global fishing fleet takes a free-for-all approach to harvesting the world’s shared resources. There’s some truth to that, but there are, in fact, laws intended to manage fishing on the high seas. They’re hard to monitor and even harder to enforce.

For decades technology has been extending the reach of fishing vessels that can now operate farther from shore, stay out longer and harvest more than ever before. Finally, the technology to monitor their activities is catching up.

New tools enable us to see what’s going on out there and to trace the catch through the supply chain from boat to plate. Increasing transparency, consumer awareness and political will are converging to tame the watery Wild West.

International-level control over global fisheries began taking shape in earnest in 1982 with the UN Convention on the Law of the Sea (UNCLOS). The treaty granted every nation with a coastline the right to control marine resources up to 200 miles from its shores. Those areas are called Exclusive Economic Zones (EEZs). Beyond those boundaries lie the high seas, encompassing roughly 60 percent of the world’s oceans. In 1995, the UN Fish Stocks Agreement was added to the treaty to set provisions for the formation of Regional Fisheries Management Organizations (RFMOs) composed of representatives from nations that fish in a set region or target a specific stock.

For example, the Indian Ocean Tuna Commission regulates tuna fisheries in the Indian Ocean, while the North East Atlantic Fisheries Commission regulates multiple commercial species throughout the North East Atlantic. There is overlap between RFMOs, some of which even have the right to regulate certain fish stocks that move between the EEZs and High seas.

Technically, the whole ocean is managed in one way or another, but regulations only address the most commercially valuable species, which leaves many species open to uncontrolled over fishing. For example, squid fishing in the South Atlantic does not fall under an RFMO.

Even among fisheries covered by RFMOs, effective management is challenging. Achieving consensus among many member states (sometimes as many as 30 nations) can be an acrimonious and messy affair, perhaps a little like folding 30 sheets of paper into a single origami lion.

When consensus is finally reached and the rules are set, monitoring and enforcement rely on the honor system because the RFMO itself has no enforcement authority beyond blacklisting non compliant vessels. It’s up to member states to enforce sanctions. There is no legal recourse for countries that accept catch from fleets that exceed quotas or breach the rules.

What’s more, RFMOs are voluntary. Nothing can stop a nation that fishes on the high seas from refusing to join or agree to the rules. In that sense, the high seas can be thought of as the last wild ungoverned territory left on Earth.

To be fair, most governments agree it’s in everyone’s best interest to manage fisheries sustainably, but the incentives and pressures to “grab it while you can” often overpower the patience and trust required to protect a shared resource for the common good, especially when you’re concerned that others are doing the same.

Enter transparency and traceability. In recent years, satellite and ground-based tracking technology has been used by industries and governments to track all manner of sea going vessels. Proprietary and expensive, this information has remained out of reach of most people, but that’s changing. Now that Global Fishing Watch is using satellite technology to make fishing activity visible to everyone, for free, on a global scale, the genie has been let out of the bottle.

It will be difficult, if not impossible, for fishing fleets to claim they’re playing by RFMO rules when they’re not. It will also be easier for those who play by the rules to make sure they’re not being cheated out of their fair share.

Other technologies are also emerging to help verify the location and method by which fish are hauled from the sea. Cameras on fishing vessels are an example some fisheries are currently experimenting with.

Transparency won’t create new authority to prosecute high-seas rule-breakers, but it will give the international community more leverage. With proof in hand that a given fleet is fishing illegally or not reporting its catch, countries can more easily deny access to their ports. More than 30 nations have signed the UN Port State Measures Agreement, which obligates them to enact strict requirements for allowing fishing vessels entrance to port. The measures are intended to ensure illegal, unregulated and unreported (IUU) fish catch has nowhere to land.

The pressure is on for countries seeking to compete in the global seafood market to follow regulations and drive out IUU fishing. Consumers are becoming increasingly aware of the state of the oceans and concerned about the source of their food. To ensure transparency continues from port to plate, new traceability tools are being introduced, and big retailers such as Costco and Walmart can move the needle by refusing to source seafood from suppliers without a sustainable certification.

Although governance on the high seas is likely to remain an exercise in cooperation and self-policing, the conditions high seas fishers face back on shore are changing. Tolerance for the old ways has diminished along with the fish, and the free-for-all may soon be coming to an end.

What Does an AIS Message Look Like Anyway?

Automatic Identification System (AIS) messages are transmitted over radio waves. The system was designed, in part, so that vessels could “see” the positions of nearby ships on a monitor and avoid collisions. These radio signals are received by satellites and used for many monitoring purposes. Each boat can broadcast a distinct message as often as every two seconds. We receive more than 20 million AIS messages a day.  When we get them, they’re just strings of code. The code below is one AIS message from one boat. Read more

IUU – Illegal, Unreported, Unregulated Fishing

The term IUU crops up frequently on our site and in discussions of the global fishing industry. It stands for illegal, unreported and unregulated fishing, and it is one of the most serious threats to the sustainability of world fisheries. Read more

What Ports Can Tell Us

Ports provide an important source of information to help us combat Illegal fishing and understand the science and economics of global fisheries. “They serve as the interface between land and sea for fishing vessels,” says Wessley Merten, our data and fisheries analyst at Oceana. “Wherever there’s a port, there’s an interaction. Whether it be offloading catch, exchanging crew, or fueling up to go back out to fish, you have officials and agencies who are theoretically greeting captains, crews and observers.”

Rendezvous at Sea: What is Transshipping?

In the commercial fishing world, transshipment is the transfer of catch from one vessel to another. During a transshipment, a fishing vessel meets up with a large refrigerated cargo-type ship, known as a “reefer.” They tie up alongside one another and drift while the fishing vessel offloads tons of catch before heading back out to the fishing grounds.

AIS and the Challenges of Tracking Vessels at Sea

At Global Fishing Watch, we hear it all the time: “Tracking commercial fishing vessels from satellites is such a great idea, and it seems so easy!” In fact, we’ve received a few questions from our readers asking us why this isn’t just a simple hack of publicly available data. Read more

Beyond the Horizon

Most of the oceans are over the horizon and under the waves. As a result, the ocean is incredibly difficult to monitor. With regards to fishing, most of our data on where and when fishing occurs comes from data collected at port or through the logs of Read more

Who Owns the Fish: High Seas and the EEZs

To look out over the ocean at a horizon that stretches for thousands of miles, it’s almost easy to understand how we have allowed overfishing to become such a serious problem. It’s that very quality of limitlessness that led the world to believe there would always be enough. Read more
