Demography

  1. ABI, ii) biomass which takes x%gentime to rebuild, iii) ssb where r=2*FMSY, iv) global MSY, v) predator ration, i.e. partial catch based on M2

Figure 1 Time to recover from different depletion levels, vertical lines are half (white) and one (red) generation time

Figure 2 \(ABI_{MSY}\) for different depletion levels, and years of rebuilding, vertical lines are half (white) and one (red) generation time

If there is a strong stock recruitment relationship, i.e. steepness is low or there is depensation, you cam get apparent recovery under ABI, as recruitment declines, so tg=here are more older fish in the population due to recruitment collapse
