On 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.

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
‘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.
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
