Pattern-based control rules for fisheries management

"In this paper, we make use of information from natural patterns to address each of these three elements of control rules to illustrate how each can be treated in a way that fully accounts for all of the complexity involved (i.e., the infinite set of relevant factors). Specifically, macroecological patterns are used to identify some of the problems caused (rather than solved) through the conventional application of control rules. We find that 1) harvested populations should be maintained at levels from 60-100% larger than what is often considered desirable in conventional management, 2) control rules should be curvilinear (rather than involving two linear segments) with harvests at levels that are between 56% and 72% of maximum when resources populations are at 40% of unharvested levels, and 3) harvest rates commonly need to be less than 10% of the magnitude of those used in much of today's management." by C.W.
