In response to fisheries declines and delayed population recoveries, many management agencies globally are integrating alternative strategies that incorporate precautionary and ecosystem considerations, increasingly focusing on climate variability and change. Here, we quantitatively evaluate how these themes have been incorporated into the science and management plans for Canada’s fisheries by analyzing the content of 905 research and management documents published by the Fisheries and Oceans Canada (DFO) for the Atlantic and Eastern Arctic regions. We found that the precautionary approach was mentioned much more frequently (44%) than climate change (11%) or ecosystem approaches to fisheries management (1%). Of research documents that mentioned climate change, 61% contained only a single reference to it, suggesting that it is not quantitatively evaluated in the science that informs the advisory and decision-making processes. Most references to climate change in the DFO research documents expressed high uncertainty of how climate change would impact the stock dynamics. We propose explanations for this and discuss approaches for increasing the incorporation of these themes into Canada’s fishery management.

领先或落后：气候变化考虑因素在多大程度上被纳入加拿大渔业管理？

为了应对渔业衰退和人口恢复延迟，全球许多管理机构正在整合纳入预防和生态系统考虑因素的替代战略，越来越关注气候变异和变化。在这里，我们通过分析加拿大渔业和海洋部 (DFO) 为大西洋和北极东部地区发布的 905 份研究和管理文件的内容，定量评估这些主题如何被纳入加拿大渔业的科学和管理计划。我们发现，与气候变化 (11%) 或渔业管理生态系统方法 (1%) 相比，预防方法 (44%) 被提及的频率要高得多。在提到气候变化的研究文件中，61% 只包含一个参考，表明它没有在为咨询和决策过程提供信息的科学中进行定量评估。DFO 研究文件中对气候变化的大多数引用都表达了气候变化将如何影响股票动态的高度不确定性。我们对此提出解释并讨论将这些主题更多地纳入加拿大渔业管理的方法。
