Error in Underlying AIS and VMS Data

Global Fishing Watch has resolved an underlying data error in the platform.

If you accessed Global Fishing Watch automatic identification system (AIS) and vessel monitoring system (VMS) data between January 26 to April 9, 2024, there may have been errors in fishing effort and fishing event data.

We have now fully resolved the AIS and VMS errors and updated sources from January 26, 2024, onwards so that AIS and VMS data are now appearing correctly in the map, platform and APIs. 

However, any use of the estimated AIS and VMS fishing data during the time range of January 26 to April 9, 2024, should be assumed to be incorrect and will require revision to ensure accuracy in fishing estimates.

Our advice is to repeat any analysis completed with the correct data. We are sorry for any inconvenience caused.
