研究了在集合种群系统中重建过度捕捞鱼类种群的最优路径,发现系统层面的恢复路径与假设种群独立时不同,例如延长某些区域的禁渔期以加速其他区域恢复。

Abstract

A contentious issue in recent fisheries management debates has been how to rebuild overfished marine fish stocks. We investigate the economic and ecological nature of rebuilding plans in a metapopulation system. We find “most rapid approach paths” for system‐wide recovery that differ from prototypical paths that might be chosen when populations are assumed independent. For example, moratoria in some patches may be extended in order to speed the recovery of other patches in the system. We also investigate the costs of second‐best policies that depend on the degree of spatial heterogeneity, the nature of the linkages, and the dispersal rates.
