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.
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. [2]
Juvenile fish have four to five bold vertical black bars on a light background and can be mistaken for sheepshead at first glance, but are distinguished on closer inspection because sheepshead have teeth and black drum have chin barbels. These stripes usually fade to dull gray as the fish grow from 12 to 24 inches (30 to 61 cm) in length.
The crevalle jack is a powerful, predatory fish, with extensive studies showing the species consumes a variety of small fish, with invertebrates such as prawns, shrimps, crabs, molluscs and cephalopods also of minor importance. Dietary shifts with both age, location and season have been demonstrated, which led some researchers to postulate the ...
The lookdown is silvery on both sides with a darker tinge on top. A young fish has several faint vertical bars that fade as it grows. [3] The longest lookdown known was 48.3 cm (19.0 in) long, [5] and the heaviest weighed 2.1 kilograms (4.6 lb). [6]
Juveniles act as cleaner fish and establish cleaning stations. Species recorded as being clients of juvenile French angelfish, include jacks, snappers, morays, grunts, surgeonfishes and wrasses. [1] [2] These fish are active during the daylight hours, but seek shelter in their designated hiding spot where they return every night. [19]
Newly released figures from the California Department of Fish and Wildlife estimate the number of Sacramento River fall-run Chinook salmon in the ocean this year at nearly 166,000 fish — down ...
A separate study, (Neal, 1993), answers this by conducting preliminary experiments where adult Garibaldi were exposed to live fish with various colorations. [7] Which resulted in the normal-colored juvenile being attacked more (not less as you'd expect with intraspecific camouflage) than the adult-colored juvenile. [7] A hypothesis known as ...
