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

这项研究涉及全球气候变化和捕捞方法的交叉点，为成年太平洋鲑鱼（Oncorhynchus spp.）。加拿大的水生生态系统正在逐渐变暖。反过来，具有重要经济意义的渔业也感受到了深刻而迅速的影响。丰富和可持续的太平洋鲑鱼种群在经济、文化、政治和生态上对加拿大都很重要。事实上，加拿大最后剩下的大型野生鱼类渔场主要是五种太平洋鲑鱼。在温暖水域进行的鲑鱼捕捞导致大量鱼类逃逸或被放生，可能是不可持续的，因为压力、伤害、感染加剧和引发潜伏疾病造成的延迟死亡率很高。这些问题可能对河内渔业最严重，因为这是成年人返回迁移通常最温暖的地方，而像弗雷泽河这样的河流系统在最近几十年里已经变暖了约2摄氏度。我们将进行
