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

   estimates from an integrated tag-based assessment are influenced by various aspects of a multi-year tagging ... emerged within this overall trend. The results show that in the early stages of the tagging program, a ... high tag size-overlap is imperative to maximise the likelihood of a robust assessment. Tagging fish ... with a low tag size-overlap, even with large numbers, is likely to result in overestimates of biomass ...
