GLOBAL - Transshipment, the transfer of goods from one boat to another, is a major pathway for illegally caught and unreported fish to enter the global seafood market. It has also been associated with drug smuggling and slave labor. Illegal in many cases, transshipment has been largely invisible and nearly impossible to manage, because it often occurs far from shore and out of sight. Until now.
With the release of the report - The Global View of Transshipment: Preliminary Findings, the Global Fishing Watch presents the first-ever global footprint of transshipment in the fishing industry.
The report explains how data scientists from SkyTruth and Global Fishing Watch (a partnership of Oceana, SkyTruth and Google) analyzed Automatic Identification System (AIS) signals from ships at sea to developed a tool to identify and track 90 percent of the world's large refrigerated cargo vessels, ships that collect catch from multiple fishing boats at sea and carry it to port.
According to the analysis, from 2012 through 2016, refrigerated cargo vessels, known as "reefers," participated in more than 5,000 likely transshipments (instances in which they rendezvoused with an AIS-broadcasting fishing vessel and drifted long enough to receive a catch).
In addition, the data revealed more than 86,000 potential transshipments in which reefers exhibited transshipment-like behavior, but there were no corresponding AIS signals from fishing vessels. Brian Sullivan, Google's lead for Global Fishing Watch, will present the findings at the Economist World Ocean Summit in Indonesia.
The report, along with the underlying data and our list of likely and suspected transshipments, will be freely available on our website, globalfishingwatch.org.
