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
Fishing in the North Sea Fishing in the North Sea Fishing in the North Sea is concentrated in the southern part of the coastal waters. The main method of fishing is trawling. Annual catches grew each year until the 1980s, when a high point of more than 3 million metric tons (3.3 million S/T) was reached. Since then, the numbers have fallen back to around 2.3 million tons (2.5 million S/T) annually with considerable differences between years. Besides the fish caught, it is estimated that 150,000 metric tons (165,000 S/T) of unmarketable by-catch are caught and around 85,000 metric tons (94,000 S/T) of dead and
