1. 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

   and the resulting data should not be used in stock assessments with only few years of data available ... . Biomass estimates generally improved with more and better quality tagging data, however important nuances ... emerged within this overall trend. The results show that in the early stages of the tagging program, a ... with a low tag size-overlap, even with large numbers, is likely to result in overestimates of biomass ...
