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
Abstract: By way of simulation, this study investigated how the bias and precision of biomass ... estimates from an integrated tag-based assessment are influenced by various aspects of a multi-year tagging ... over 60-70%. Biomass estimates were largely unaffected by the type of catch history. Therefore ... , creating ‘contrast’ in the data by strongly reducing the fish biomass is not needed for tag-based ...
