No other species travels these great distances without an overhead view – salmon travel to and from their spawning grounds, guided by some internal sonar that is remarkably precise.   Jason Hwang says, “They swim thousands of kilometres and return to the exact same spot. We still don’t fully understand how they do it. It is truly remarkable.” Over the past 100 years, their numbers have crashed. We know many of the reasons why – spawning ground disruption or destruction, coastal eel grass depletion, predators, and the science also points to impacts from open-pen fish farms. Then there is the mystery of what happens when they head out to the open ocean. Add in a changing climate and the impact is devastating on British Colu
