Haddock in Division VIb (Rockall) - Last years the discards are significantly reduced as a result of the small number of young haddock in the population: discard ratio ~ 47% ( ) and 34% in the recent period ( ); in ~8% - Estimates of discards in the EU is a main uncertainty in the assessment and forecasts
Whiting in Division VIa (West of Scotland) MSY: Catches in should be reduced. The selection pattern should be improved in the Nephrops (TR) fleet.

Cod in Divisions VIIe k (Celtic Sea cod) Because of the large year class is now entering the fishery, which was not anticipated in last year s advice or TAC, there will be a large inconsistency between the TAC set for (43 t) and the predicted landings for that year, assuming the current fishing mortality ( 5 t). Therefore, in the absence of any effort limitation and/or TAC revision, high discarding will occur
