UBC research helps migrating salmon survive mortality hot-spot

A study by UBC researchers found that only 40% of coho salmon remained alive three kilometers from release, and fewer than one-quarter reached the Lions Gate Bridge 20 kilometers away. The 'mortality hot-spot' was confirmed in Burrard Inlet, but the research also suggests ways to increase survival rates through changing release locations.
