Climate warming, pathogen expression, and capture locale: recent and emerging challenges for managing Pacific salmon fisheries

这项研究涉及全球气候变化和成年太平洋鲑鱼(Oncorhynchus spp.)捕捞做法的交集。加拿大的水生生态系统正在逐渐变暖。反过来，对经济上重要的渔业也产生了深远而迅速的影响。丰富和可持续的太平洋鲑鱼资源对加拿大的经济、文化、政治和生态都很重要。事实上，加拿大最后剩下的大型野生鱼类渔业主要以太平洋鲑鱼的五个品种为特色。在温暖水域捕捞鲑鱼并导致大量逃逸或放生的鱼可能是不可持续的，因为压力、伤害、感染加剧和引发潜伏性疾病造成的延迟死亡率很高。对于河内渔业来说，这些问题可能是最大的，因为这是成年回流迁徙通常最温暖的地方，像弗雷泽河这样的河流系统在最近几十年里变暖了约20摄氏度。我们将进行一项

This research concerns the intersection of global climate change and fishing practices for adult Pacific salmon (Oncorhynchus spp.). Canadian aquatic ecosystems are progressively warming. In turn, profound and rapid effects are being felt on economically important fisheries. Abundant and sustainable Pacific salmon stocks are important economically, culturally, politically and ecologically to Canada. Indeed, Canada's last remaining large fisheries on wild fish heavily feature the five species of Pacific salmon. Salmon fisheries that occur in warm water and that result in large numbers of escaped or released fish may be unsustainable because of high levels of delayed mortality due to stress, injury, enhanced infection and triggering of latent diseases. These issues will likely be greatest for in-river fisheries because this is where the adult return migration is typically warmest and river systems like the Fraser River have warmed by ~2oC in recent decades. We will conduct a
