    The existing bootstrap used in the assessment of icefish biomass in CCAMLR subarea 48.3 was compared to an alternative rescaled bootstrap to compare the performance of the methods. The differences between the method were small (less than 5%) except for slightly lower 5%iles in 2002 and 2004 in the rescaled bootstrap.
