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
. Biomass estimates generally improved with more and better quality tagging data, however important nuances ... with a low tag size-overlap, even with large numbers, is likely to result in overestimates of biomass ... and the resulting data should not be used in stock assessments with only few years of data available ... . In contrast, with a 100% tag size-overlap even low numbers of releases and subsequent recaptures ...
