Victoria hosted a send-off celebration for an international collaboration of scientists embarking on a 25-day research expedition into northern salmon ecology on Wednesday.
On Wednesday, 12 scientists from Canada, Russia and the U.S. gathered aboard the Pacific Legacy No. 1, the Canadian charter vessel they’ll call home for nearly a month while they analyze the tissue, muscle and stomach content of hundreds of fish and other species in the Gulf of Alaska, where Pacific salmon from Canada, Japan, Korea, Russia and the U.S. are thought to mingle.
Researchers will also analyze ocean conditions and depths at which the fish swim, as well as the food they eat. Ultimately the marine experts hope to come back with a better picture of salmon ecosystems and just how rapidly changing ocean conditions are impacting them.
Richard Beamish, B.C. scientist for the Pacific Biological Station, said discoveries made on the expedition will change how Pacific salmon are managed.

“It’s doing something that has never been done before and providing information that eventually will allow us to understand the mechanisms that regulate salmon abundance and will allow everybody to be professional stewards,” Beamish said.
The expedition follows a similar study in 2019, when researchers found depleted salmon stocks and specimens in unexpected regions – like sockeye salmon in the Central Pacific and coho far off shore.
On the upcoming trip the researchers will learn more about what those findings might mean. They’ll also test a hypothesis about the strength of juvenile salmon, which Beamish said may have a stronger survival rate during their first ocean year if they grow faster and quicker in their first months of life.
