Abstract

Worm et al. (Research Articles, 3 November 2006, p. 787) reported an increasing proportion of fisheries in a "collapsed" state. We show that this may be an artifact of their definition of collapse as a fixed percentage of the maximum and that an increase in the number of managed fisheries could produce similar patterns as an increase in fisheries with catches below 10% of the maximum.

摘要

沃姆等人（《研究论文》，2006年11月3日，第787页）报告称，处于“崩溃”状态的渔业比例在上升。我们表明，这可能是他们将崩溃定义为最大产量的固定百分比所导致的假象，而且管理渔业数量的增加可能会产生与捕捞量低于最大产量10%的渔业数量增加类似的模式。
