Abstract A thrust toward fisheries co-management systems occurred globally throughout the 1990s. This was partially influenced by the collapse of groundfish stocks including the iconic northern cod and other fisheries resources in Newfoundland and Labrador (NL). The management system for NL snow crab burgeoned during this period, largely in the absence of biological information for the resource. There is a high volume of theoretical literature advocating for the benefits of fisheries co-management, but little documented perspectives from fisheries scientists actively engaged in such management systems, nor literature detailing how co-management regimes could affect scientific research or assessment programs. In this paper, in context of a large fishery, we provide specific examples of how co-management processes can influence scientific research and monitoring programs and the biological functioning of important marine resources. We undertake critical evaluation on topics including spatial scales of management, fishery timing, fishery closures, collaborative research, and harvester perceptions of stock size. We conclude there are both scientific advantages and disadvantages to operating within co-management systems, but that the NL snow crab management system has evolved to promote processes problematic to provision of the best possible science advice. We conclude that adaptive co-management measures are required to address several current challenges in order to maximize scientific value within this system. In general, the paper demonstrates how flexibility is needed by all partners involved in resource co-management systems to adapt to fundamental scientific principles inherent in changing methodologies and the generation of knowledge.

渔业共同管理复杂性的生物学观点：纽芬兰和拉布拉多雪蟹的案例研究

摘要 整个 1990 年代，全​​球都出现了对渔业共同管理系统的推动。部分原因是底层鱼类种群崩溃，包括纽芬兰和拉布拉多 (NL) 标志性的北部鳕鱼和其他渔业资源。NL 雪蟹的管理系统在此期间蓬勃发展，主要是在缺乏资源生物信息的情况下。有大量理论文献提倡渔业共同管理的好处，但很少有文献记载积极参与此类管理系统的渔业科学家的观点，也没有详细说明共同管理制度如何影响科学研究或评估计划的文献。在本文中，在一个大型渔业的背景下，我们提供了共同管理过程如何影响科学研究和监测计划以及重要海洋资源的生物功能的具体例子。我们对管理空间尺度、渔业时间、渔业关闭、合作研究和收割机对种群规模的看法等主题进行批判性评估。我们得出的结论是，在共同管理系统内运作既有科学优势也有劣势，但 NL 雪蟹管理系统已经发展到促进有问题的过程，以提供最好的科学建议。我们得出的结论是，需要采取适应性共同管理措施来解决当前的几个挑战，以最大限度地提高该系统内的科学价值。一般来说，
