[Extract] Pacific salmon–among the 'elite' athletes of the sea–hatch in rivers, spend their adult years in the ocean, and then make one last incredible journey up-river to reproduce in their natal streams. This final trek, or spawning run, returns 10 million salmon to North American west coast rivers annually where, for up to 1000 km, they encounter turbulent currents, narrow deep gorges (particularly the Fraser River's appropriately named Hell's Gate) and fluctuating temperatures. However, humans may have created a new hurdle that salmon may not be able to overcome. Tony Farrell and his colleagues in Canada suggest that increasing river temperatures profoundly affect the salmon's athletic capacity, and are largely responsible for salmon vanishing from their migration routes.
