Table 23. 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 large coastal shark complex (K=20x106 individuals, only 8 CPUE series, and 1983 Early Rec data point removed), sandbar (K=12x106 individuals and 1983 "early Rec" CPUE point removed), and blacktip (K=12x106 individuals and Gulf Reef logs CPUE series removed) with the Prager form are compared to those reported by one of the reviewers.

2 Nfin/K is the stock abundance in the final year of management (2008, 2018, or 2028) as a percentage of K

Table 25 (continued). 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 large coastal shark complex, sandbar, and blacktip (two MRFSS CPUE series removed) with the Prager form are compared to those reported by one of the reviewers. Predictions of alternative harvesting policies are also included.
