The complete stock structure of North Sea sandeel is unclear, and although several reproductively isolated sub-populations have been identified, some exchange appears to take place between neighbouring populations in early life stages. From 2010 onwards ICES has presented advice for the North sea sandeel divided into 7 management areas, based on the assumption that this will better reflect the stock structure and enable improved management avoiding local depletion (ICES, 2010a). This profile represents the SA2 area: South Eastern North Sea. Since 2017, the name of this management area changed to Sandeel Area 2r because of a change in the statistical rectangles (divisions 4.b-c and Subdivision 20) included in management area (ICES, 2017).
