5. Influence of the quality and quantity of data from a multi-year tagging program on bias and precision of biomass estimates from an integrated stock assessment – update

   SSB0 and SSB status in the assessment year stabilized or were relatively small with a tag size-overlap ... and the resulting data should not be used in stock assessments with only few years of data available ... estimates from an integrated tag-based assessment are influenced by various aspects of a multi-year tagging ... . Biomass estimates generally improved with more and better quality tagging data, however important nuances ...
