In New Zealand, however, CPUE still provides the basis for pāua stock assessments. In this study, a simulation model was developed to investigate how CPUE indices are influenced by spatial use patterns and by management intervention, and whether spatial and temporal generalised linear mixed models can mitigate biases arising from spatial use patterns.
