About this Site

Welcome to the online combined IUU vessel list. The purpose of this site is to provide best known updated information on all vessels that appear on the lists of vessels that have been identified by Regional Fisheries Management Organisations (RFMOs) and INTERPOL associated with IUU fishing activities.

Each RFMO IUU vessel list and the vessels subject to Interpol Purple Notices have been merged into a single list. However a major challenge of all IUU vessel lists is that the vessel information provided in them is static, reflecting only how the vessel was originally listed. As IUU vessels frequently change their identification (name, flag etc.) to hide their activities, this means that few if any of the listed vessels are operating with the identity under which they were listed. Using a large number of intelligence sources, the Combined IUU Lists attempts to provide updates on changes in identity information and geographic location on all vessels contained, with the goal of improving the effectiveness of the original IUU lists as a tool to combat illegal fishing.

To date, nine regional fisheries management organisations (RFMOs) maintain or share lists of vessels that have been found to carry out or support IUU fishing within their own or adjacent convention areas. These RFMOs are the:

  • Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR)
  • Inter-American Tropical Tuna Commission (IATTC)
  • International Commission for the Conservation of Atlantic Tunas (ICCAT)
  • Indian Ocean Tuna Commission (IOTC)
  • Northwest Atlantic Fisheries Organisation (NAFO)
  • North East Atlantic Fisheries Commission (NEAFC)
  • South East Atlantic Fisheries Organisation (SEAFO)
  • Western and Central Pacific Fisheries Commission (WCPFC)
  • South Pacific Regional Fisheries Management Organisation (SPRFMO)

In addition, since 2013 Interpol member states have issued Purple Notices to request or provide information regarding fishing vessels that are wanted for illegal activities. Notices are published by INTERPOL’s General Secretariat at the request of National Central Bureaus (NCBs) and authorized entities. Purple Notices are used ‘To seek or provide information on modi operandi, objects, devices and concealment methods used by criminals.’

Information recorded on the combined IUU vessel list comprised a vessel’s name and name history, flag and flag history, International Maritime Organization (IMO) number (where one could be assigned), international radio call sign (IRCS) and call sign history, owner(s) and operator(s) information (where available), technical details (e.g. vessel type and tonnage), the IUU vessel listing RFMOs, and dates and reasons for IUU vessel listing and delisting.

Searching the Vessel List

  • Click 'Search' tab
  • The first time you visit the search page, ALL vessels will appear in the 'Results' list below.
  • When you enter text (or numbers) into the search box, only vessels that have matching text or numbers within their vessel details will be displayed.
  • For example - If you are searching for a particular vessel by name, just start typing the name and the results list will instantly change to show only listings that match
  • ALL data will be searched, so you don't need to know whether a name is current or old, for example

Refining the Search

  • You can include / exclude vessels listed by particular RFMOs or INTERPOL, and those that are Currently Listed / Delisted, using the checkboxes

Sorting the Results list

  • Initially, vessels will be sorted alphabetically by RFMO vessel name
  • Click on a column header (eg 'IMO Number') to sort the list by that column
  • Click column header again to invert the sort order

Viewing Vessel Details

  • Click on the 'details' link in the results list to see more about that vessel. Blank boxes indicate fields for which there is currently no data, or where data is pending
  • Click 'Return to Search' if you want to go back to your previous results list
  • Click 'New Search' if you want to start over


The Combined IUU Vessel List is maintained by Trygg Mat Tracking (TMT), a Norway-based organisation that provides expert fisheries intelligence analysis to national authorities and relevant international institutions. The website is intended as a public service to provide an updated and consolidated real time listing of all the main high seas RFMO IUU vessel lists, and vessels identified in INTERPOL Notices. The Combined IUU Vessel List is also the public face of TMT’s much broader global fishing vessel database and analytical system that is continuously being updated to identify and monitor the enormous global fishing vessel fleet for illegal activities.
