NGO collaboration will help fishery managers ensure transfer of catch is both legal and verifiable The transfer of fresh catch from fishing vessels to refrigerated cargo ships is an important but often opaque part of the industrial fishing sector. A new public global monitoring portal is a turning point in efforts to manage this activity.

A carrier vessel is a type of vessel used to transport fish, supplies, and crew to and from fishing vessels, allowing fishing vessels to stay out at sea for longer periods of time. A carrier vessel can receive catch, or ‘tranship’, from one or more fishing vessels at sea or in port and then offload

The data in the portal is created using automatic identification system (AIS) data. AIS transmits a ship’s position so that others can be made aware of its location and avoid potential collision. AIS transmits a ship’s location, speed, direction, and identity information, such as a vessel’s name and flag. Global Fishing Watch uses AIS data

The data in the portal currently spans from January 2017 until 72 hours ago. We adjusted our authorization categories to enable the inclusion of the most recent month of data. Although all of our AIS data is provided until 72 hours ago, the registry records are updated at the beginning of each month with a

Encounters may indicate potential transshipment activity between two vessels that both appear on AIS. Encounters are estimated using AIS data, including distance between the two vessels, vessel speeds, and duration in a given area. An encounter is defined as when two vessels, a carrier vessel and encountered fishing vessel, are detected on AIS data as

Loitering is when a single vessel exhibits behavior indicative of a potential encounter event. Loitering is estimated using automatic identification system (AIS) data, including vessel speed, duration in a given location, and distance from shore. Loitering occurs when a vessel travels at average speed of < two knots, while at least an average of 20

Ports in the portal are based upon the Global Fishing Watch anchorages dataset, a global database of anchorage locations where vessels congregate. The dataset contains over 160,000 individual anchorage locations, which are further grouped into nearly 32,000 ports. A vessel is considered to have visited a port when within three kilometers of an anchorage location
