For the landings:
- The precision level 2 shall be targeted at the stock level for both Group 1 and Group 2 species. If necessary, specific stock-based samples shall be added if metier-based sampling fails to provide the appropriate precision for length distributions at the stock level.
For the discards:
- Data related to quarterly estimates of discards length and age composition for Group 1 and Group 2 species must lead to a precision of level 1.
- Weight estimates of Group 1, 2 and 3 species must lead to a precision of level 1.
(Chapter III B/B1/4.2.a/b)
For the recreational fisheries:
- Data related to annual estimates of the catches in volumes must lead to a precision of level 1.
