At the end of each year the JRC prepares coverage reports in relation to the data calls under its responsibility.

The coverage reports provide an overview of the timeliness and contents of the MS data submissions to JRC. JRC evaluations of MS data submissions are based on data specifications defined in the various DCF data calls issued by DG MARE.

In addition, the Coverage Reports summarise findings regarding major data omissions and data deficiencies detected by JRC and by Expert Working Groups convened under the STECF. The Coverage Reports may support end user feedback provided to DG MARE to facilitate the evaluation of EU MS compliance with DCF provisions.
