Here, we show that adult Atlantic salmon Salmo salar returned about 2 weeks later from the feeding areas in the North Atlantic Ocean to the Norwegian coast, through a phenotypically plastic mechanism, when they developed as embryos in c. 3°C warmer water than the regular incubation temperature. This finding has relevance to changes in migration timing caused by climate change and for cultivation and release of S. salar.
在这里,我们表明,当成年大西洋鲑鱼(Salmo salar)在比正常孵化温度高约3°C的水中发育成胚胎时,它们会通过一种表型可塑性机制,大约在两周后从北大西洋的觅食区返回挪威海岸。这一发现与气候变化导致的洄游时间变化以及大西洋鲑的养殖和放流有关。
