Table 13. Estimates of the mid-year vulnerable biomass (mt) for 2009 from the four models and three fishery selectivities. Note that the vulnerable biomass is conditional on the selectivity, and assumes that a selectivity is applicable to the entire population. The values do not apply separately to each region.
