Some like it hot, but not salmon

Atlantic salmon (Salmo salar) are an important species of fish both for their ecological value and commercial value. These anadromous fish are spawned in rivers, travel to the sea to grow and mature before returning to the stream or river they were born in to spawn the next generation. As such the ability to swim against strong currents and up natural barriers is important, which is why a recent study published in the Canadian Journal of Zoology is concerning.
