2.1. Data description

Main characteristics

2.1.1 Describe shortly the main characteristics of the statistics 

Aquaculture production statistics as defined in Regulation (EC) 762/2008 contain four different datasets:
AQ2A - Aquaculture production volume at first sale for human consumption (excluding hatcheries and nurseries) by species, FAO Major Area, cultivation method and aquatic environment.
AQ2B - Production of fish eggs (roe) for human consumption at first sale by species, by FAO Major Area, cultivation method and aquatic environment.
AQ3 - Input to capture-based aquaculture, i.e. wild seed, by species.
AQ4 - Production of juveniles and fertilised eggs at first sale for further on-growing or release to the wild by species.
The production volume is measured in tonnes live weight (TLW) and economic value as unit price in national currency per tonne (NAC_T/TLW), with the exception of juveniles and fertilised eggs which are measured in numbers.
In addition, a fifth dataset (AQ5) provides information on the size (in hectares, 1000 cubic metres or metres) of aquaculture production facilities segmented by species group, FAO Major Area, cultivation method and aquatic environment.


Reference period

2.1.2 Reference period of the data collection

National legislation

2.1.3 Is there a national legislation covering these statistics? No
If Yes, please answer all the following questions.

2.1.7 Year of entry into force of the national legislation
2.1.8 Please indicate which variables required under EU regulation are not covered by national legislation, if any.
2.1.9 Please indicate which national definitions differ from those in the EU regulation, if any.
2.1.10 Is there a legal obligation for respondents to reply?


Additional comments to data description

There is no national legislation on aquaculture statistics. All respondents are required to submit in due time true and complete data under section 28 "Obligations of respondents and access to information" of the Official Statistics Act. Link to the Official Statistics Act: Riigiteataja website.
2.2. Classification system

The following variables are recorded with regard to aquaculture production:

  • 'Species' means the species of aquatic organisms identified using the international 3-alpha code as defined by the FAO (ASFIS List of Species for Fishery Statistics Purposes). Individual species are grouped in aggregates according to their taxonomy and living habits. These aggregates are specified in the International Standard Statistical Classification of Aquatic Animals and Plants (ISSCAAP) and indicated in the ASFIS list.
  • 'FAO Major Areas' means the geographical areas as defined by the FAO (CWP Handbook of Fishery Statistical Standards). The FAO Major Areas covered are: 27 'Northeast Atlantic', 37 'Mediterranean and Black Sea', 34 'Atlantic Eastern Central', 5 'European inland waters', 1 'African inland waters'.
  • 'Cultivation method' includes ponds, cages, tanks and raceways, enclosures and pens, recirculation systems, others and not specified. For molluscs also on-bottom and off-bottom systems.
  • 'Aquatic environment' distinguishes the water types 'fresh water' and 'salt (sea and brackish) water'.
    The methods and water types are defined in Annex I of Regulation (EC) No 762/2008.
2.3. Coverage - sector

On-farm commercial aquaculture production destined for human consumption.
2.4. Statistical concepts and definitions

According to Regulation (EC) 762/2008, aquaculture production means the output from aquaculture at first sale. In the case of animals, only production for human consumption is considered, while ornamental or functional species as well as feed production are excluded. By contrast, aquatic plants are recorded notwithstanding their final use.
The production volume is expressed in tonnes live weight [TLW] of the product. This weight includes all shells and bones. Data on the economic value of the production are reported as unit price in national currency per tonne [NAC_T]. The production of hatcheries and nurseries is reported in numbers and expressed in millions. Data on the structure of the aquaculture sector are expressed in thousand cubic metres, hectares or, optionally, 'metres rope length' depending on the method.
2.5. Statistical unit

2.6. Statistical population

All commercially active aquaculture production facilities within the national territory

Data are stored in and processed automatically by the software VAIS (Survey Data Information System) developed by Statistics Estonia. There are various automatic checks set up in VAIS. The automatic checks are set up, for example, for missing data, comparison of quantities in relation to a previous period, and checks for quantity and unit price values per 1 kg. When an error appeared, a statistician from the Data Processing and Registers Department contacted the enterprises by e-mail or phone and then the data were corrected. A statistician from the Economic and Environmental Statistics Department also checked the completeness and accuracy of the dataset and any errors were clarified by the Data Processing and Registers Department. All the totals and aggregates disseminated were compiled based on the data collected with the electronic survey “Fish and crayfish farming”.
