2. Selection of commercially exploited species:
Identification of
the appropriate area
Match of existing spatial
units to that area
Celtic Sea MSFD subregion vs ICES ecoregion
Celtic Sea ICES ecoregion
Celtic Sea MSFD subregion

3. Selection of commercially exploited species:
Identification of
the time period • • • • •
The number of species contributing ≥ 0.1% of total catches in the Celtic Seas using
different historic time periods

4. Selection of commercially exploited species:
Identification of
the % threshold
