REGIONAL COORDINATION GROUPS
The Regional Coordination Groups for Fisheries Data Collection (RCGs) are the main hub for cooperation in the collection and management of fisheries data across the European Union. Established under Regulation (EU) 2017/1004, these groups bring together national experts and representatives from Member States, and the European Commission to coordinate activities within each marine region.
Reliable scientific advice for fisheries management under the Common Fisheries Policy (CFP) depends on access to consistent, high-quality data. In the EU, this information is collected by Member States through the EU Data Collection Framework (DCF), established by Regulation (EU) 2017/1004. It defines what data must be collected and shared, covering biological, environmental, technical and socio-economic aspects of fisheries, aquaculture and related processing sectors.
The DCF also requires Member States to cooperate and coordinate their data collection activities. This coordination is carried out through Regional Coordination Groups (RCGs), built around either by marine region or by type of fisheries, with a dedicated group focusing on economics issues. Together, these groups support a coordinated, end-user-oriented approach to fisheries data collection across the EU and, where relevant, with third countries.

Who is involved?
- EU Member States are at the core of the RCGs, participating through appointed National Correspondents and experts.
- The European Commission, supporting coordination and ensuring the implementation of the DCF.
- End users of the DCF data, informing about their needs, offering feedback on submitted data and providing recommendations.
- Where relevant, third countries sharing waters in a certain region or interests in a common fisheries are invited as observers.
The overall framework is completed with the RCGs Secretariat, which facilitates communication and workflows throughout the network by providing support and shared working environments.

What do RCGs do?
RCGs provide a coordination framework for EU Member States on fisheries data collection by marine region or type of fisheries. This includes agreeing methodologies and approaches, cooperating on scientific surveys, coordinating sampling activities, addressing data issues, setting up and managing compatible datasets at regional level, developing Regional Work Plans and engaging with end users.
When issues affect more than one region, coordination takes place between RCGs and with the European Commission.

Why do RCGs matter?
Fisheries management relies on scientific advice to support decisions that affect ecosystems, fishing activities and the communities that depend on them. To be robust and usable, this advice requires data collected in a consistent and comparable way. When methods, coverage or timing differ, uncertainty increases and the quality of the evidence base is reduced.
RCGs support the delivery of reliable, comparable fisheries data for scientific advice. By coordinating data collection across countries and fisheries, RCGs help ensure that data meet the needs of end users and contribute effectively to fisheries management at regional and EU level.
