Table 32. Estimated expected values (EV) of the means and coefficients of variation (CV) of marginal posterior distributions for output parameters from the Bayesian surplus production model analysis. Results for the blacktip shark (with the Early Rec CPUE series only, and with all the other CPUE series except Early Rec) with the Prager form are compared to those reported by one of the reviewers. Predictions of alternative harvesting policies are also included.
