Dimension: Nominal catches
Type: Quantity
Unit: Tonnes
Description: The "nominal catches" concept refers to the landings converted to a live weight basis; the closely related concept "landings" refers to the quantities on a landed weight basis. In many fisheries the landed quantities are identical to the quantities caught, but there are many instances where the catches on board fishing vessels or factory ships are gutted, eviscerated, filleted, salted, dried, etc., or reduced to meals, oil, etc. The data on the landings of such species and products require conversion by accurate yield rates (conversion factors) to establish the live weight equivalents (nominal catches) at the time of their capture. The database does not include quantities discarded after catching.
Key: Aquatic species
Type: Species
Code system: Scientific name (at the species, genus, family or higher taxonomic levels);
Code system: FAO English, French or Spanish name;
Code system: Inter-agency 3-alpha code (as derived from the "ASFIS List of species");
Code system: Taxonomic code (as derived from the "ASFIS List of species");
Aggregation: The species are arranged in 50 ISSCAAP groups of species, which constitute the 9 ISSCAAP divisions (or Major groups) of the FAO 'International Standard Statistical Classification of Aquatic Animals and Plants' (ISSCAAP.) The 50 ISSCAAP groups of species can also be grouped in:
Aggregation: FAOSTAT group classification;
Aggregation: Yearbook Main Groups classification;
Aggregation: Taxonomic classification consisting of 4 levels of aggregation (Orders, Families, Genera and Species.)
Key: Country or Area
Type: Geographic
More info: The term also covers territories, cities, land areas, as well as provinces, districts, enclaves, exclaves and other parts of territories or combinations of countries or areas
Code system: FAO multilingual code of not more than twelve characters used for statistical purposes;
Code system: Country or area names in English, French or Spanish;
Code system: ISO 3-alpha code;
Code system: ISO 2-alpha code;
Code system: FAO three-digit numerical code;
Aggregation: Continents;
Aggregation: Continents and regions (each continent is divided into regions);
Aggregation: Economic class (developed countries; developing countries);
Aggregation: Economic groups (developing countries; transition markets; industrialized countries.)
Key: Statistical divisions of the FAO Major Fishing Area 51
Type: Geographic
Code system: FAO name in English, French or Spanish;
Code system: FAO code.
Aggregation: To coarsely match the RECOFI area as described in Article IV of the RECOFI agreement, the Subarea "51.3 - Western Arabian Sea" of the FAO major fishing area "51 - Western Indian Ocean" has been subdivided into two statistical divisions, namely "51.3.1 - Oman Sea" and "51.3.2 - South-western Arabian Sea". Data included in the RECOFI capture database are hence available by two divisions:

51.2.0 - Gulf
51.3.1 - Oman Sea
