自20世纪60年代以来，全球鲍鱼产量下降了60%以上，并且还在继续下降，这表明未能可持续地管理这些资源。本文讨论了鲍鱼生物学的各个方面，使可持续管理成为问题。鲍鱼资源由许多小型（100 -1000米）自招微型种群组成，成熟时的大小变化很大。这就造成了管理规模与股票组成单位规模之间的不匹配。这种“规模暴政”使组成微种群容易受到“公地悲剧”的影响，使资源容易受到连续耗竭的影响，尽管显然有严格的区域规模管理。我假设，除了鲍鱼，在一系列空间尺度上，未被认识到的空间复杂性危及了许多渔业的监测、评估和管理。我认为，鲍鱼渔业和更广泛的渔业领域面临的一个主要挑战是使渔业监测、评估和管理的规模适应鱼类组成单位的实际规模，并调动所需资源，充分满足无数微型鱼类的全球需求。作为应对这一挑战的一部分，建议增加利用以领土为基础的捕鱼权和设立一个新的渔业从业人员类别。
Global production of Haliotids (abalone) declined more than 60% since the 1960s and continues to decline, indicating a failure to manage these resources sustainably. This paper discusses facets of abalone biology which make sustainable management problematic. Abalone resources are comprised of many small (100s-1000s m) self-recruiting microstocks with highly variable sizes-at-maturity. This causes a mismatch between the scale of management and the scale of component units of stock. This "tyranny of scale" leaves component microstocks vulnerable to the "tragedy of the commons" and resources vulnerable to serial depletion despite apparently rigorous regional scale management. I postulate that beyond abalone, and across a range of spatial scales, unrecognized spatial complexity compromises monitoring, assessment, and management in many fisheries. I suggest that a major challenge for abalone fisheries and the field of fisheries more generally, is to adapt the scale of fisheries monitoring, assessment, and management to the actual scale of component units of stocks, and to mobilize the resources required to adequately address the global needs of a myriad of microstocks. An increased use of territorially based fishing rights and a new class of fisheries practitioners are proposed as part of the answer to this challenge.
