1. Working Party on Fisheries Statistics 14 October 2013
Item IV.B Data collection, compliance, quality, confidentiality and other issues (Document FISH/334)

2. Table of Contents
Compliance
Data quality
Other issues

3. Compliance In case of non compliance
Automatic reminders, s and letters at head of unit, Director and General director level sent
The compliance monitoring exercice will take into account the quality of the data
Until now no infringement procedure launched

4. Data quality Edamis Web portal to absolutely use
Tables forwarded to NAFO and FAO
Clear trafic monitoring and follow up of compliance
Utility of guidelines = your comments are the welcome
In case of revision, send a complete dataset of revised year, if partial update = loss of data

5. Data quality : major mistakes to avoid
Use the most recent Excel templates to create the correct XML file before sending it
Use the correct classification and codes for species and fishing areas
Some fish species are caught in some areas where they cannot be
For reporting catches on unknown subareas, use the "xxxxx_NK" areas codes
Use the correct units required for reporting data: too many data in kilos instead of tonnes
SBW is an aggreggate (SEA + BRK) not a type of water
OTH (="other") is not a fish species

6. Data quality : major mistakes to avoid
Do not send duplicate data, this happens regularly in Landings tables
Check for outliers
Make sure you select in eDAMIS the correct dataset name, year and country to send your data
Do not send data by unless the data manager requests it
Do not forget to inform us about methodological changes

7. Our checks for data validation
Formal data checks are performed during the import of data into our database
File format check.
Existence of codes (against dictionaries);
Duplicate records.
Check for comparability with previous years (outlier detection);
Check whether the country has already reported a given species for the given area in the past;
Check whether the reported combination of species, environment and production method exists.
Check quantities or prices equals to 0
Check for empty values
Duplicate : two values for same specie region/environment depending dataset
Outliers : more or less 50% calculation of the median
Values equal to 0 = to avoid, a fish has a value, only caught species to declare
Empty values to avoid as well, quantities in tonnes with the values, values with quantities, not one without the other

8. Other issues Revision of the area codelist
As regards the dissemination of European catch data on Eurobase, unofficial and/or unused sub-aggregate area codes exist, for example 27_3_BC, 27_3_B-D (Baltic Sea), 27_4_AB, 27_4_BC, 27_7_BC, 27_7_A-F, 27_7_D-K, 27_7_DE, 27_7_F-K, 27_7_G-K. Do these sub-aggregates need to be maintained?

9. Other issues
Methodological reports for aquaculture data Regulations (EC) 762/2008 every year (Annex 6)
Revision of aquaculture data is planned in the coming months
