 Gross value of production The gross value of the production is normally collected together with production quantity statistics and the value is optimally collected at the farm-gate level (IMF 2014), that is, the value per unit (price) of the product at... More

 Total revenue Total revenue is composed of several variables. Gross sales of the aquaculture production part of the core variables (refer above). Direct subsidies - including direct payments; excluding social benefit payments and indirect subsidies e.g. reduced duty on inputs... More

 Total costs Total costs is composed of several variables. Cost data can be obtained from the financial records of the aquaculture operation or enterprises and these data are mostly difficult to obtain. Even when such data are available, they are... More

 Retained catch: Estimated component of the catch which is retained on board during a fishing trip (refer catch concept diagram). An estimate of the retained catch is reported as total live weight of fish retained and in some fisheries the... More

  Nominal catch (also referred to as nominal landings): Landed weight converted to a live weight basis often by use of a conversion factor. Nominal catch is often referred to as the live weight equivalent of the landed weight or... More

  Bycatch: Component of the catch which represents non-targeted fish associated with the catch of the target species or group towards which fishing effort is directed, or other aquatic organisms taken incidentally during the course of fishing (e.g. birds, mammals,... More

 All countries or areas have official and formal designations, many of which are not well suited for use in statistical databases and publications, particularly in tabulations and graphs. These designations are therefore often simplified. The list of countries or areas... More
