What is Supply balance and other methodologies

All methodologies used by the EUMOFA for collecting, managing and analysing data are described in detailed. More specifically:

  • Data collection outlines all sources of data and collection methodologies used for feeding in the EUMOFA database;

  • Data management describes all harmonisation procedures currently carried out by the EUMOFA. All correlation tables used are also reported;

  • Data analysis includes the supply balance methodology developed and adopted by the EUMOFA.

Data collection Data collection

Metadata 1 - Data collection
“Data collection” describes the methodology used by the European Market Observatory for Fisheries and Aquaculture products (EUMOFA) to collect data from different sources, providing also all needed details and specifications of data collected (type of data, frequency, time-lag, origin of data, etc.).
Title Description Action
Annex 1 Selected products at EU/National level

Data management Data management

Metadata 2 - Data management
“Data management” describes the procedures adopted by the European Market Observatory for Fisheries and Aquaculture products (EUMOFA) to harmonise data collected.
Title Description Action
Annex 1 List of Main Commercial Species and Commodity Groups
Annex 2 Lists of EUMOFA Preservation states and Presentations
Annex 3 Correlation of Main commercial species/Commodity group and ERS codes
Annex 4 Annex 4 Correlation of Main commercial species/Commodity Groups and CN-8 from 2001 to 2016
Annex 5 Correlation table between ERS presentation and preservation state codes and EUMOFA's presentations and preservation states
Annex 6 Correlation table of EUROSTAT presentation codes and EUMOFA's preservation states and presentations
Annex 7 Conversion factors by CN-8 codes from 2001 to 2016
Annex 8 Ports/Seaboard correlation table

Data analysis Data analysis

Metadata 3 - Data analysis
"Data analysis" describes the two methodologies used by EUMOFA for:
  • Assessing the origin of Imports and Exports in terms of production methods (fishery vs aquaculture);
  • Developing the Supply Balance sheets for the calculation of the apparent consumption.
Both analyses are strongly linked since the assessment of the origin of Imports and Exports allows the calculation of shares of caught and farmed products in Imports and Exports within the Supply Balance.
