Figure 3.
Effects of a spawning-ground reserve (left) and feeding-ground reserve (right) on catch from the fishery. The feeding-ground ratio RF of catches describes the fraction of the total allowable catch that is permitted in the feeding grounds as opposed to in the spawning grounds. The thickness of lines and the size of symbols increase with RF between 0 (all fishing occurs in the spawning grounds) and 1 (all fishing occurs in the feeding grounds). Fishing occurred for 100 years with an annual harvest ratio of 0.5. Values shown are means for 30 independent model runs. The legend in panel B applies to all panels.
