Focal points of the FAO Fisheries and Aquaculture Statistics and Information Service for country statistics are contacted to provide relevant information, however, when focal points are not readily available, then recognized national aquaculture experts and/or aquaculture statisticians from a broad range of institutions who have worked with FAO are consulted.
Collection Method: Aquaculture data are collected at an individual farm level or by administrative units using an MS-Excel submission form. The completed MS-Excel form, once validated, are then used to create the NASO maps.
Authors (see data source section) who complete the MS-Excel form, can indicate, in the "Data clearance" section of the form, which data can be displayed in NASO fact sheets and which data should be used only for internal use at FAO to improve reported statistics.
Validation methods: Validation is conducted by comparing the total aquaculture production quantities reported in the NASO MS-Excel form by Organism Division (fish, molluscs, crustaceans, seaweeds, other) and Environments (freshwater, brackishwater and marine) against FAO statistics using FAO FishStat Plus software. Any anomalies identified are corrected and updated in the MS-Excel form.
