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.

Additional comments to data description
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

Off-farm commercial aquaculture production destined to human consumption.
2.4. Statistical concepts and definitions

According to Regulation (EC) 762/2008, aquaculture production means the output from aquaculture at first sale. For animals, only production for human consumption is considered, while ornamental or functional species as well as feed production is excluded. By contrast, aquatic plants will be 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 for 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' according to the method.
2.5. Statistical unit

Aquaculture production facility.
2.6. Statistical population

All commercially active aquaculture production facilities within the national territory.

The confidentiality of statistical data is required by law, and the staff who conducting the statistical survey has the same legal obligation to protect confidentiality.Thus, in Article 27 of the Law on Statistics of BiH states that "When collecting, processing, delivering and distributing statistical data of Bosnia and Herzegovina, the competent authorities, including bodies at the entity level, undertake all the measures of organizational, regulatory, administrative and technical nature that are needed to protect the confidentiality of data from unauthorized access, publication and use", and Article 28 of the same Law states" Person who, when performing their duties, have access to confidential information must comply with the provisions of the provisions of this law and after they cease to perform their functions.
11.2. Confidentiality - data treatment
11.2.1 Describe the procedures for ensuring confidentiality during dissemination

The protection of individual data has regulated by the Law on Statistics of Bosnia and Herzegovina ("Official Gazette of BiH", No. 26/04 and 42/04), the Law on Statistics in the Federation of BiH (Official Gazette of the F BiH, No. 63/03 i) / 09), Law on Statistics of the Republic of Srpska (Official Gazette of RS, No. 85/03) and Law on Personal Data Protection (Official Gazette of BiH, No. 49/06).
