Figure A3.3 Temperature effects on the optimal management of Northeast Arctic cod (Gadus morhua) with and without the effect of acidification. Depicted are catch and recruits (top panel), fishing mortality and mean age of catch under optimal management (middle panel), and net revenue and spawning stock biomass (lower panel). The left-hand column show results for warming only, while the right-hand column show results for the combined effect of warming and acidification. It is important to note the marked change in scale for the two sets of vertical axes.
