Understanding fish movement in the Arctic is paramount during the current era of rapidly warming seas, receding sea ice and associated shifting species distributions and fishing effort. We synthesized the literature and identified key knowledge gaps on the movement ecology of Arctic cod (Boreogadus saida) and Polar/Ice cod (Arctogadus glacialis, both Gadidae) in the context of climate change. Standardized web‐based English‐language literature searches yielded 51 articles directly relevant and 122 indirectly relevant for the movement ecology of these species combined. Most articles were primarily relevant to B. saida (85% of total filtered articles), occurred during open water season (49/38%) with focus on distribution (32/22%), predators (30/22%), seasonal spawning/feeding movements (22/19%), sea ice association (22/26%), climate change (20/15%) and vertical movements (17/19%) with few focused on horizontal dynamics (3/0%; B. saida/A. glacialis, respectively). Disproportionate data resolution has resulted in greater predictive power of movement models for the European (29% of articles) and North American (86%) Arctic regions relative to the logistically challenging Central Arctic Ocean and Russian‐Siberian Arctic shelves (both 7%). The movements of circumpolar Arctic gadids are dependent on complex dynamics that include regional currents, the longevity of ice‐flows and polynyas, water stratification and coastal hydrology. Dependence on these interactive and often co‐dependent processes highlights major pathways and barriers to movement and distribution at higher latitudes. Despite a recent increase in impactful research, there is a critical need for more direct research on circumpolar gadid movements to aid understanding of climate change impacts on Arctic ecosystems and fisheries.

变暖世界中的鳕鱼运动生态学：极北极小行星

在当前海洋快速变暖，海冰消退以及相关的物种分布变化和捕捞努力时代，了解北极中的鱼类运动至关重要。我们综合了文献并确定了在气候变化的背景下，北极鳕鱼（Boreogadus saida）和极地/冰鳕鱼（Arctogadus glacialis，均为加迪亚）的运动生态学方面的关键知识空白。基于标准的基于网络的英语文献搜索，得出与这些物种的运动生态直接相关的51篇文章和122篇间接相关的文章。大多数文章主要与B. saida有关。（占总过滤物品的85％），发生在开放水域（49/38％），重点在于分布（32/22％），捕食者（30/22％），季节性产卵/喂食运动（22/19％） ，海冰协会（22/26％），气候变化（20/15％）和垂直运动（17/19％）与少量集中在水平动力学（3/0％;乙。 赛达/甲。 冰川， 分别）。相对于后勤上挑战性的中北冰洋和俄罗斯-西伯利亚北极大陆架（均为7％），不成比例的数据分辨率已导致欧洲（占文章的29％）和北美（占86％）北极地区的运动模型具有更大的预测能力。北极极地周向的运动取决于复杂的动力学，包括区域性洋流，冰流和多年生生物的寿命，水层化和沿海水文学。对这些互动且通常相互依赖的过程的依赖突显了高纬度地区移动和分布的主要途径和障碍。尽管最近有影响的研究有所增加，但迫切需要对绕极旋风运动进行更直接的研究，以帮助了解气候变化对北极生态系统和渔业的影响。
