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
Migration of marine species in the Northern Atlantic Ocean outside their normal range and into more northern waters causing an array of ecological, economic, and fishery management problems. William Cheung, a professor at the University of East Anglia, in the Sea Around Us Project at the University of British Columbia concluded that the oceans were warming at an average of per decade and at per decade in tropical waters. However, the north-east Atlantic has been warming at a rate of per decade. Cheung and his colleagues were able to get these estimates by using the mean temperature of catch. They used data from 990 species within 52 marine ecosystems
