LarvalBase is a global online database of information about fish eggs, larvae and fry.It includes detailed data on the identification of very young fish and the rearing of fish species important for fisheries and aquaculture.
Fish eggs cannot swim at all, and are unambiguously planktonic. Early stage larvae swim poorly, but later stage larvae swim better and cease to be planktonic as they grow into juveniles. Fish larvae are part of the zooplankton that eat smaller plankton, while fish eggs carry their own food supply. Both eggs and larvae are themselves eaten by ...
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 ...
Juvenile fish tend to have bright colours which are completely different from the appearance of adults of that species. [5] The brown color of Stegastes apicalis was shown to arise from melanosomes containing pheomelanin [ 6 ] unlike most fish species's melanosomes that contain eumelanin .
The larvae will spend 1 to 3 months in waters over the continental shelf. The Chesapeake Bay is a popular nursery for juvenile menhaden. Larval fish will enter the Bay in late winter and early summer. The larval fish will move into lower salinity waters in estuarine tributaries while juvenile and immature fish remain in the Bay until the fall.
[14] [36] The U.S. Fish and Wildlife Service published a useful series that includes egg, larvae, and juvenile development descriptions of hickory shad. [12] A recent review of hickory shad in Chesapeake Bay places management of this species in an ecosystem context. [37] Three master of science theses also studied them. [38] [39] [40]

Adult fish also prey on fish eggs and larvae. For example, haddock were observed satiating themselves with herring eggs back in 1922. [14] Another study found cod in a herring spawning area with 20,000 herring eggs in their stomachs, and concluded that they could prey on half of the total egg production. [17] Fish also cannibalise their own eggs.
