The detection is based, since 2008, on the register of companies drawn up in previous national surveys and other administrative process operated by the Ministry. |
Objects of the service were the collection and compilation of statistical data concerning Italy and referred to the following areas: |
1) annual production (volume and unit value) of aquaculture (FISH_AQ2A_A); |
2) annual production of fish eggs intended for human consumption (FISH_AQ2B_A); |
3) annual inputs (volume and unit value) to capture-based aquaculture (FISH_AQ3_A); |
4) annual production of hatcheries and nurseries (FISH_AQ4_A); |
5) Structure of aquaculture sector (FISH_AQ5_A3) (not due for 2022) |
|
The reference context of the investigation has been circumscribed, defining the following parameters: |
Statistical unit: the statistical unit of reference for the survey is the individual aquaculture company/ company. |
Reference population: in light of previous data and in continuity with previous experience, we consider the reference population as a whole of the plants present on the Italian national territory that practice aquaculture in fresh, marine and brackish water and hatcheries and nurseries. The list, available from previous surveys, has been integrated with the updated registers of the production facilities extracted from the database of the Ministry of Health. |
Reference territory: ITALY. |
Reference period: Year of production 2022. |
Statistical variables of interest and their classifications: The statistical variables of interest include all the information, definitions, data and their aggregations as per art. 4 and Annexes I, II, III and IV of the EC Reg. 762/2008. |
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 ton (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 (not provided for 2022). |
