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.

Ide (fish) the wild in at least one site within New Zealand. Ide occurs in schools in the clear pools of larger rivers, ponds, and lakes but they may move to deeper waters during the winter before moving into shallow freshwater to spawn in the spring. The species is also found in the Baltic Sea, which has a lower salinity than most seas and in Sweden the fish spent the first year of their lives in rivers before joining the more mature fish as they migrated downstream into the Baltic Sea during the summer months. The fish then returned to the rivers
