Dimensión: Nominal catches
Tipo: Quantity
Unidad: Tonnes
Descripción: 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.

Clave: Statistical divisions of the FAO Major Fishing Area 34
Tipo: Geographic
Sistema de codificación: FAO name in English, French or Spanish;
Sistema de codificación: FAO code.
Aggregation: The FAO Major Fishing Area 34 internationally established for fishery statistical purposes, has been split into four subareas, further sub-divided into twelve divisions:

34 1 - NORTHERN COASTAL subarea, which includes three divisions:

34 1 1 - Morocco coastal
34 1 2 - Canaries/Madeira insular
34 1 3 - Sahara coastal

34 2 - NORTHERN OCEANIC subarea, which includes only one divisions:

34 2 0 - Northern oceanic

34 3 - SOUTHERN COASTAL subarea, which includes six divisions:

34 3 1 - Cape Verde coastal
34 3 2 - Cape Verde insular
34 3 3 - Sherbro
34 3 4 - Western Gulf of Guinea
34 3 5 - Central Gulf of Guinea
34 3 6 - Southern Gulf of Guinea

34 4 - SOUTHERN OCEANIC subarea, which includes two divisions:

34 4 1 - Southwest Gulf of Guinea
34 4 2 - Southwest oceanic

Tuna catches are not allocated according to CECAF statistical divisions and are grouped together into a division named "Tunas" (34 0 0). Two other divisions, namely "Northern coastal, not known" (34 1 9) and "Not known" (34 9 0), contain catches for which is not exactly known the statistical division.
