FAO TERM PORTAL

Fisheries

Originally created in 2001, the FAO Fisheries Glossary has been jointly upgraded by the Fisheries and Aquaculture Department and the Meeting Programming and Documentation Service. This upgrade stems from the need to have it become an integral part of the FAO Term Portal. It includes additional features, languages, and access to alternative definitions for currently existing terms in the FAO Term Portal. As at October 2014, the FAO Fisheries Glossary consists of approximately 1580 terms and definitions, grouped by subject areas, with relevant language equivalents being developed when new terms are added.

All definitions in the Glossary are provided with a “Definition source”, indicating the originator of the term and context in which the term is applied. Terms are provided  by FAO as well as by other institutions collaborating with FAO. FAO remains the publisher of all terms, and FAO officers maintain and update definitions in their area of expertise in collaboration with originators.

This Glossary will serve to facilitate a clearer understanding and communication in FAO's long-term objective of  achieving sustainable management and use of fisheries and aquaculture resources, enhancing international cooperation in these fields.
