Sockeye salmon migration

Every spring 10-40 million juvenile sockeye salmon leave Chilko lake in B.C. but less than two million make it back as adults. Researchers at UBC used acoustic telemetry to uncover the mysteries of what happens to these salmon.

“We’re implanting electronic tags into these little fish to implant, we’re performing little surgeries and then we’re releasing them and then tracking their migration as they head downstream,” said Nathan Furey, a PhD candidate in the faculty of forestry to CBC’s Early Edition. “We were really surprised that there was a lot of mortality occurring early on in the migration particularly in the Chilko river, soon after these smolts leave their natal lake of Chilko lake.”

The segment begins at 1:20:00. Furey also did interviews with other CBC morning radio programs across the province.
