Herring as food Herring as food Herrings are forage fish, mostly belonging to the family Clupeidae. They 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 recognized. The main taxon, the Atlantic herring, accounts for over half the world's commercial capture of herrings. Herrings played a pivotal role in the history of marine fisheries
Migration of marine species in the Northern Atlantic Ocean from 1970-2006. Using fisheries data and computer models, Cheung was able to estimate the shift of species. Species are migrating north at an average rate of per decade. The study predicted that there will be a 60% shift of species towards northern waters within the next 41 years. Migration of marine species in the Northern Atlantic Ocean The world's oceans are warming due to climate change. Climate change is caused by three major factors which are the greenhouse effect, variation in the sun's energy that reaches Earth, and changes in reflectivity within Earth's atmosphere and its surface.
