The Globe and Mail article For salmon, a deadly sea highlights results from a study conducted by Dr. David Welch and Kintama Research Services Ltd. investigating the migration of salmon. The study involved tracking 3,500 tagged salmon with the Pacific Ocean Shelf Tracking (POST) marine telemetry array.  The study was recently published in the Proceedings of the National Academy of Sciences of the United States.  Dr. Welch states, “The scientific body for a century has said the marine survival problems are happening very early in the life history. Now we are measuring that and saying, ‘Sorry, it doesn’t look like that.’ Most of the mortality is happening more than a month after entering the ocean.”  Preliminary findings of this study were presented to the Cohen Comission of Inquiry into the Decline of Sockeye Salmon in the Fraser River.
