Some populations of Fraser River salmon more likely to survive climate change: UBC study

Populations of Fraser River sockeye salmon are so fine-tuned to their environment that any further environmental changes caused by climate change could lead to the disappearance of some populations, while others may be less affected, says a new study by University of British Columbia scientists.

Genes contribute to sockeye salmon mortality in Fraser River: UBC and DFO study

Fraser River sockeye salmon with a certain genomic profile are more likely to die before spawning, contributing to the recent declines in British Columbian salmon, says a new study by researchers at the University of British Columbia (UBC) and Fisheries and Oceans Canada (DFO).
