This working paper provides a review of key life history parameters of North Pacific blue shark used in the previous stock assessment and a proposal of new biological parameters to be used in the next stock assessment. We recommend updating the following parameters: updated sex-specific growth parameters, sex-specific natural mortality at age, and parameters of stock-recruitment relationships. For the parameters of low-fecundity stock recruitment relationships, we recommend discussing the estimation method of the parameters in the upcoming meeting.
