Fishing vessels need to be marked in such a way that they can be easily identified in accordance with international standards. Correct use of vessel markings enables a fishing vessel to be linked to its identity, as contained in vessel records. Through proper marking the operational and/or historical information related to the vessel can be retrieved, including its fishing and other authorisations.

Marking fishing vessels with suitable identifiers is an important tool for fisheries management. It enables identification of fishing vessels in port or at sea, which allows for monitoring of compliance to rules and regulations applicable to the vessel and its fishing activities. Clearly marked vessel identifiers form the basis for a vessels’ inclusion in a vessel register or authorised vessel list. In addition, markings facilitate safety at sea by enabling physical identification and communications between vessels, and can help to deter vessel theft.

This leaflet was developed for the Western Central Atlantic Fishery Commission (WECAFC) who are working to increase awareness and build capacity on vessel marking and identification, among WECAFC members, in support of the national and regional fight against illegal, unreported and unregulated (IUU)
fishing and the establishment of a regional vessel record. Appropriate vessel identification and linked registries represent the basis for improving fishery management and conservation in the region.
