There are two families in the order Clupeiformes; the herring family (Clupidae) and the anchovy family (Engraulidae) and are relatively small, silver-coloured fish. They swim in large, pelagic schools and feed on plankton. They are occasionally found near the shore, however they usually swim further out in the open sea at depths up to 200 m. Most species are capable of producing a lot of eggs each spawning event, up to 200.000 per adult female. A large share of the global wild catch consists of haring-like fish. Not everything is used for direct human consumption, a large share is processed as fish meal or fish oil that form the essential ingredient for fish feed in aquaculture. Haring-like fish swim in large schools which makes them susceptible to large scale (industrial) fishing.
The garfish is a long and slender fish with elongated jaws. This species can be found high up in the water column where it hunts for smaller fish. The garfish can grow out to be 90 cm long and weigh a maximum of 1.3 kilograms. Furthermore, the garfish has green coloured fish bones.
