Historical catch reconstruction and CPUE standardization for the stock assessment of oceanic whitetip shark in the Western and Central Pacific Ocean

This is a companion paper to the 2019 stock assessment for oceanic whitetip shark (Carcharhinus
longimanus) (Tremblay-Boyer et al. 2019) detailing the historical catch reconstructions and
CPUE standardization approaches used to create the data inputs to the assessment. We
repeat here the methods from the main assessment report, provide a discussion of key results
and present detailed model diagnostics on the observer data-based catch reconstructions and
CPUE standardization. Other inputs to the assessment were described in Tremblay-Boyer et
al. (2019).
