The Fishbase Glossary contains definitions of more than 2,600 terms related to ichthyology, taxonomy, ecology, conservation, population dynamics, genetics, oceanography, geography and related disciplines. Terms and definitions are given in English, French, Spanish and Portuguese. Please contact us if you have any comments on our definitions or suggestions for additional terms.

The glossary was originally derived from the various help messages in FishBase and checked against similar glossaries in taxonomic books and in biological, geographical and other dictionaries (e.g., UNEP/WCMC 1995). It also contains all vernacular names of fish families and the acronyms, addresses and additional information on 200 fish collections. Later we added (with permission) selected terms from glossaries in FAO Species Catalogues; the Zoological Code of Nomenclature (1985); the Marine Ecosystem Classification for the Tropical Island Pacific (Holthus and Maragos 1995); Fish Population Dynamics in Tropical Waters: a Manual for Use with Programmable Calculators (Pauly 1984); Guide Book to New Zealand Commercial Fish Species (Armitage et al. 1994); Field Guide to Trawl Fish from Temperate Waters of Australia (May and Maxwell 1986); Trawled Fishes of Southern Indonesia and Northwestern Australia (Gloerfelt-Tarp and Kailola 1984); Continental Shelf Fishes of Northern and North-Western Australia (Sainsbury et al. 1985); Status of Fishery Resources off the Southeastern United States for 1993 (Southeast Fisheries Science Center 1995); and several others. The definitions were edited and cross-referenced; you can get to the cross-referenced terms by double-clicking on the respective field.
