Annex 6 to the Regulation. These reports contained detailed information on the quality of the data and on the methods used in collecting them. The national quality reports following the ESS guidelines were collected in the ESS Metadata Handler.

The European reference metadata on aquaculture statistics are published on the Commission (Eurostat)’s public database with the data tables listed above. The metadata are reviewed annually.

2.5.Data confidentiality

One shortcoming affecting the aquaculture statistics collected under the Regulation was the high number of confidential data cells. There were two main reasons for this. Firstly, the Regulation calls for a highly detailed data structure, which in turn leads to very fragmented data. Secondly, the aquaculture sector is highly specialised in its structure. This makes for a sector with a limited number of enterprises dealing in very few species with one main production method. As a result, a large number of data on single species and aggregates have become confidential.

In 2015 almost half of the Member States faced data confidentiality issues with the main aquaculture production dataset. This meant that EU aggregates remained confidential for most species, often because of confidential data in a single Member State. However, the national total production volume and value could be published for 2014 and 2015 for all Member States. Confidential data from one Member State prevented publication of the EU aggregate for capture-based input to aquaculture. EU-wide production of fish eggs for human consumption remained confidential because of niche production in three Member States. The data on the production from hatcheries and nurseries were confidential in several Member States.

The Commission (Eurostat) and the Member States have invested time and effort to make as many figures as possible available to data users, while safeguarding statistical confidentiality and keeping the process as efficient as possible.

3.Burden and cost-effectiveness

The time and effort needed to collect, compile and process the data at national level every year varied a great deal. Half of the Member States needed less than 10 weeks and the other half more than 10 weeks to compile the datasets, as required by the Regulation. The time needed for the whole data collection process has not decreased in any Member State since the entry into force of the Regulation, indicating that it has been difficult for them to boost efficiency.

However, some Member States reported that they had managed to reduce the burden on respondents. Questionnaires remained unchanged and respondents found that answering them became a matter of routine. Online questionnaires and tailor-made support for enterprises also helped reduce the burden. Respondents needed three hours on average to fill out the questionnaire. The number of respondents ranged from 4 000 in Germany to under 50 in Malta, Belgium, Cyprus and the Netherlands.

The ESS carried out a cost analysis of European statistical products. Cost estimates for aquaculture statistics were received from 20 Member States. The average annual cost of national data collection was approximately EUR 66 000, or an average of 0.18 % of the total value of aquaculture production. Some cost estimates did not reflect the total production cost of aquaculture statistics, covering only the direct costs that the national institute concerned had incurred.

4.Conclusions

In recent years aquaculture statistics have evolved into a stable set of data with fairly timely, complete and consistent output for data users not only at the European and global levels, but at national level as well. They provide policymakers, industry and civil society with solid foundations on which to build the sector’s future development.

Some Member States have continued to face problems with the timeliness and punctuality of the data collection and delivery. The Eurostat data collection guidelines have helped make the aquaculture data collection more consistent.

The main shortcoming affecting aquaculture statistics is the amount of confidential data. This is linked to the detailed breakdown of the data requirements set by the Regulation and to the aquaculture sector’s specialised and concentrated structure.

Member States reduced the burden on respondents, but did not make clear, measurable efficiency gains. The average annual cost of producing aquaculture statistics was EUR 66 000 per country. However, the average share of the data collection costs in the total economic value of aquaculture production was rather low.

5.Recommendations

The Commission (Eurostat) will continue working with the Member States on good practices, recommendations and guidelines to reduce the amount of confidential data delivered to Eurostat under the Regulation.

At the national level the use of electronic questionnaires should be further encouraged, as it helps make data collection more efficient. National data collection guidelines and helpdesks offering respondents tailor-made support are other examples of good practices.

The Commission (Eurostat) strives for constant improvement in the quality and availability of European statistics. It is also committed to reducing the burden on Member States and respondents. To this end, it has included in its Annual Work Programme 2017 7 a project on streamlining and simplifying fishery statistics. This project looks at current data collection and draws up a strategy for making the aquaculture statistics more fit for purpose. The project ensures coordination to dovetail with statistics collected under Regulation (EU) 2017/1004 and better harmonisation with the standard aquaculture questionnaire recommended by the Coordinating Working Party on Fisheries Statistics 8 .

     The Coordinating Working Party on Fisheries Statistics (CWP) was established in 1959 by resolution 23/59 of the FAO Conference to coordinate the fishery statistical programmes of regional fishery bodies and other inter-governmental organisations. Its purpose is to (i) keep under continuous review the requirements for fishery statistics (including aquaculture); (ii) agree standard concepts, definitions, classifications and methodologies for the collection and collation of fishery statistics; and (iii) propose ways of coordinating and streamlining statistical activities among relevant intergovernmental organisations (http://www.fao.org/fishery/cwp/en). Recently, it has developed a draft standard aquaculture questionnaire as a recommendation for minimum requirements for aquaculture statistics.
