An assessment of toothfish in Subarea 48.3 using CASAL
model was selected to best represent the fishery and the available data sources. This incorporated two ... fleets with different selectivities, and fitted to catch length frequencies, tag recapture data, CPUE ... data, and the survey recruitment series (treated as a relative index). This produced excellent fits to ... the catch length frequencies, but a poor fit to the early CPUE data, for which a substantial process ...
