Figure 9: Biomass of age-structured species groups over catch calculated from Chatham Rise Atlantis model simulations with no cap on recruitment (A, C), recruitment capped at R0 (B, D), recruitment steepness values h ∈ (0.5, 0.7, 0.9) for the 1970–2016 hindcast period (B, D) and h set at 0.9 for myctophids, with three catch scenarios: (1) Zero catch; (2) Status quo catch; (3) Half catch, for the 2016–2046 projection period (C, D).
