The overall aim was to improve ageing precision and the quality of age compositions provided to ICES Working groups. Further aims were:
• to find out the ageing agreement between countries and between the two methods of using whole otoliths and sections mounted in resin
• analyse and discuss the level of agreement between readers 

• look at otoliths where there is disagreement and resolve any differences
• to re-read a selection of the exchange otoliths after discussing disagreements
• if time permits the workshop will also look at otoliths brought by participants
• to produce a reference collection of agreed ages for training etc
