Herring Herring Herring are forage fish, mostly belonging to the family Clupeidae. Herring often move in large schools around fishing banks and near the coast. The most abundant and commercially important species belong to the genus "Clupea", found particularly in shallow, temperate waters of the North Pacific and the North Atlantic oceans, including the Baltic Sea, as well as off the west coast of South America. Three species of "Clupea" are recognised, and provide about 90% of all herrings captured in fisheries. Most abundant of all is the Atlantic herring, providing over half of all herring capture. Fishes called herring are
Latitude of the Gulf Stream and the Gulf Stream north wall index Regier and Stommel model compared with observations over 40 years (The graphs are in standardised units). The latitude of the north wall has been linked via the atmospheric circulation with a variety of changes at the other side of the North Atlantic Ocean [17], [19], [20], and. The Continuous Plankton Recorder Survey, now run by the Sir Alister Hardy Foundation for Ocean Science in Plymouth, UK, has monitored the plankton in the surface waters of the North Sea and NE Atlantic for more than half a century. Over most of this time many of the zooplankton in these regions have
