Juvenile fish are marketed as food. Whitebait is a marketing term for the fry of fish, typically between 25 and 50 millimetres long. Such juvenile fish often travel together in schools along the coast, and move into estuaries and sometimes up rivers where they can be easily caught with fine meshed fishing nets.
The juvenile fish are paler and can have an almost whitish background colour. [7] The maximum recorded total length is 50 centimetres (20 in)—although they are more commonly around 19.1 centimetres (7.5 in)—and the maximum published weight is 1.9 kilograms (4.2 lb).
Fish, eels, some lobsters, blue crabs (and so forth) do have distinct juvenile habitats, whether with or without overlap with adult habitats. In terms of management, use of the nursery role hypothesis may be limiting as it excludes some potentially important nursery sites. In these cases the Effective Juvenile Habitat concept may be more useful.
Whereas FishBase is a database about adult finfish, LarvalBase is a database about the juvenile stages of fish. Juvenile fish often feed differently and occupy different habitats than the adults do. LarvalBase complements FishBase by providing information about these early stages of life.

A fish hatchery is a place for artificial breeding, hatching, and rearing through the early life stages of animals—finfish and shellfish in particular. [1] Hatcheries produce larval and juvenile fish , shellfish , and crustaceans , primarily to support the aquaculture industry where they are transferred to on-growing systems, such as fish ...
During the free-floating stage, many changes take place in the young halibut, including the movement of the left eye to the right side of the fish. During this time, the young halibut rise to the surface and are carried to shallower water by prevailing currents. At six months, the halibut have their adult form and are about 1.4 in (3.6 cm) long ...
