Remote Electronic Monitoring: How Cameras on EU
Vessels Can Help to End Overfishing
To effectively manage our oceans and end overfishing, regulators must be able to collect high-
quality data on the health of fish populations and ensure compliance with regulations. Managers
have historically relied on a variety of methods to collect this data (e.g. logbooks, human observers,
dockside monitoring, at-sea patrols), but these tools cover a limited proportion of fishing activities,
are subject to bias or misreporting, and can be expensive and imprecise. As a result, most fishery
managers lack the basic science information that they need to get the rules of the game right, and
equally do not have the right compliance information to ensure that fishers play by those rules. To
address this, the revised EU Fisheries Control Regulation must mandate the introduction of Remote
Electronic Monitoring with cameras onboard all vessels over twelve metres in length, alongside an
additional percentage of small-scale vessels that are at a high risk of breaching the rules of the
Common Fisheries Policy (CFP).
Remote Electronic Monitoring – What it is, and why it matters.
Remote Electronic Monitoring with cameras (REM) does a good job of describing itself. A combination of
cameras and sensors fitted onboard fishing vessels to collect large amounts of independent information on
everything that is caught - including marine wildlife that might not be the main target.

Having access to up-to-date and reliable catch data allows managers to confirm that vessels are following
the rules, but can also inform the delivery of stock assessments, catch quotas, and policy decisions that
successfully encourage ecosystem recovery and sustainable practices within the EU fleet. Moreover, it
creates opportunities for fishers to improve their practices and add value to their catch by showing supply
chain partners that they operate legally and sustainably.
