'''Threats:''' Herring stocks collapsed worldwide in the 1970s due to overfishing. Subsequent poor recruitment led to a complete fisheries closure in 1977, after which the stock eventually recovered, and fisheries reopened. Herring is closely monitored and managed throughout to ensure stock survival. | '''Threats:''' Herring stocks collapsed worldwide in the 1970s due to overfishing.

The dominant species of Herring in the North Sea is the Atlantic Herring ([https://www.marinespecies.org/aphia.php?p=taxdetails&id=126417 Clupea harengus]). These herring form expansive schools and are widely distributed throughout the North Atlantic, including the North Sea. Their migrations follow a distinct pattern: during the spring and summer, they move inshore to coastal waters for spawning, while in winter, they shift to deeper, offshore areas. As they mature, herring undergo a pelagic phase, spending time in the open ocean before returning to coastal waters as adults for spawning. Herring is a keystone species in the Nort Sea as they are a vital prey species for larger predators such as cod, seabirds and marine mammals. | The dominant species of Herring in the North Sea is the Atlantic Herring ([https://www.marinespecies.org/aphia.php?p=taxdetails&id=126417 Clupea harengus]).

The Baltic Sea is home to a specific subspecies of the Atlantic Herring, known as the Baltic Herring (''[https://www.marinespecies.org/aphia.php?p=taxdetails&id=234068 Clupea harengus membras]''). This subspecies is adapted to the lower salinity levels of the Baltic Sea and have a unique genetic profile. Like the Atlantic Herring, the Baltic Herring also undertake seasonal migrations, but within the Baltic Sea as they move to shallower coastal areas for spawning during the summer. This also means that the Baltic Herring may be more sensitive to changes in environmental conditions due to its specialized adaptation to this unique ecosystem. | The Baltic Sea is home to a specific subspecies of the Atlantic Herring, known as the Baltic Herring (''[https://www.marinespecies.org/aphia.php?p=taxdetails&id=234068 Clupea harengus membras]'').

The Clyde Marine Region is primarily home to the Atlantic Herring ([https://www.marinespecies.org/aphia.php?p=taxdetails&id=126417 Clupea harengus]). These herring form expansive schools and are widely distributed throughout the North Atlantic, including the Clyde Marine Region. Their migrations follow a distinct pattern: during the spring and summer, they move inshore to coastal waters for spawning, while in winter, they shift to deeper, offshore areas. As they mature, herring undergo a pelagic phase, spending time in the open ocean before returning to coastal waters as adults for spawning. The mixing of freshwater from the river and seawater in the Clyde estuary can influence the distribution and behavior of herring in this region. | The Clyde Marine Region is primarily home to the Atlantic Herring ([https://www.marinespecies.org/aphia.php?p=taxdetails&id=126417 Clupea harengus]).
