Structure   
 
Dimension : Nominal catches
Type : Quantity
Unité : 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.
Clé : Aquatic species
Type : Species
Systéme de codification : Scientific name (at the species, genus, family or higher taxonomic levels);
Systéme de codification : FAO English, French or Spanish name;
Systéme de codification : Inter-agency 3-alpha code (as derived from the "ASFIS List of species");
Systéme de codification : Taxonomic code (as derived from the "ASFIS List of species");
Aggregation : The species items 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.)
Clé : Country or Area
Type : Geographic
Plus d'infos : 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
Systéme de codification : FAO multilingual code of not more than twelve characters used for statistical purposes;
Systéme de codification : Country or area names in English, French or Spanish;
Systéme de codification : ISO 3-alpha code;
Systéme de codification : ISO 2-alpha code;
Systéme de codification : 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.)
Clé : Major inland and marine fishing areas
Type : Geographic
Systéme de codification : FAO name in English, French or Spanish;
Systéme de codification : FAO code.
Aggregation : For statistical purposes the FAO Major Fishing Area 34 - Southeast Atlantic has been split into five subareas, further sub-divided into eleven divisions:

47 1 - WESTERN COASTAL subarea, which includes six divisions:

47 1 1 - Cape Palmeirinhas
47 1 2 - Cape Salinas
47 1 3 - Cunene
47 1 4 - Cape Cross
47 1 5 - Orange River
47 1 6 - Cape of Good Hope

47 2 - AGULHAS COASTAL subarea, which includes two divisions:

47 2 1 - Middle Agulhas
47 2 2 - Eastern Agulhas

47 3 - SOUTHERN OCEANIC subarea

47 3 0 - Southern oceanic

47 4 - TRISTAN DA CUNHA subarea

47 4 0 - Tristan da Cunha

47 5 - ST HELENA and ASCENSION subarea

47 5 0 - St Helena and Ascension

Tuna catches are not allocated according to statistical divisions and are grouped together into a division named "47 0 0 - Tunas". Three other divisions, namely "47 1 9 - Western coastal, not known", "47 2 9 - Agulhas coastal, not known" and "47 9 0 - Not known", contain catches for which is not exactly known the statistical division.
