11.2.2 Impacts of Fishing
When fishing mortality is imposed in the model, the fishable cohorts (60 to 90 mm
through 180 to 210 mm), after some initial fluctuation, settle into equilibrium at
population levels considerably lower than when fishing did not occur (55,000 to
63,000 with fishing compared to 70,000 to 90,000 without fishing). As before, more
