Information aquaculture at plant level is compiled by The Danish Fisheries Agency.

Frequency of data collection

Data are collected yearly.

Data collection

Data concerning Danish quotas and catch are compiled by The Danish Fisheries Agency. Data concerning fish stocks are compiled and developed by ICES. Data concerning aquaculture are compiled by The Danish Fisheries Agency.

Data validation

Data concerning quotas and catches are processed and validated by The Danish AgriFish Agency cf. Documentation of statistics. Data concerning fish stocks are processed and validated by ICES. If relevant the data are updated during the year. Data concerning aquaculture are processed and validated by The Danish AgriFish Agency cf. Documentation of statistics. The received data are reviewed and obvious errors are corrected.

Data compilation

The resource account for natural aquatic resources: data concerning quotas and catches are aggregated to be in line with the areas for which stock assessment are developed including total allowable catch (TAC) are established. The Danish share of the stock is calculated as the share of Danish quotas relative to TAC. Based on this information the following balance is developed: Opening stock + growth - catch = Closing stock. The growth is calculated as residual. The grouping used in other statistics have been applied in this account. The resource account for aquaculture is established in a similar way. Resources transferred from one plant to another as well as resources reclassified or transferred to put & take are also taken into account. The growth is calculated as residual. The grouping used in other statistics have been applied in this account except for the group Trout and Salmon which has been separated in freshwater and sea farms. In the monetary account for aquaculture average prices for fish harvested for consumption has been applied. For stocks average prices for two years have been applied.
