Habitat: Benthopelagic Main role: Prey Trophic level: 3,4
Diet: They prey on zooplankton and fish larvae.
Threats: Highly commercial. Herring stocks collapsed 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 the North Sea to ensure stock survival. Herring is also sensitive to pollution.
Herring is a month-by-month, computer generated data layer following calculations made by the ecosystem simulation (EwE).
Different pressures generate by human activities (noise, bottom disturbance, surface disturbance, artificial substrate) have different, complex effects on marine species in terms of movement, survival and procreation.
Herring are caught by all fishing fleets, but mostly by industrial and pelagic trawl.
