, a comprehensive online database about finfish. 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.

LarvalBase aims to include all the key data on finfish larvae, with an emphasis on standardising the data, making it easy to extract and combine data with other data, and offering powerful presentation tools. It draws on the traditional primary source

Aquaculture, also known as aquafarming, is the farming of aquatic organisms such as fish, crustaceans, molluscs and aquatic plants. Aquaculture involves cultivating freshwater and saltwater populations under controlled conditions, and can be contrasted with commercial fishing, which is the...

 scientists and managers to get the information they need on the species that concern them, because the relevant facts can be scattered and buried across numerous journal articles, reports, newsletters and other sources. It can be particularly difficult for people in developing countries who need such information. An answer to this situation is to consolidate all the available information, drawn from the global sources, into an easily accessed database. The database will be particularly useful if the data has also been standardised and validated. It was with such considerations that the FishBase

 project was born in 1988. FishBase is now the world's main
database on finfish with over 30 million hits a month. However, FishBase does not include detailed information on fish eggs and juvenile fish. In 1998 the LarvalBase project was launched to remedy this.
