UBC scientist says chinook salmon may be wiped out

Study involving UBC scientist says Chinook salmon could be wiped out by 2100

By The Canadian Press

VANCOUVER – New climate-change research involving a University of British Columbia scientist predicts that one of the West Coast’s most prized salmon stocks could be wiped out over the next 85 years.

A study has concluded that there is a five per cent chance of a catastrophic loss of the chinook salmon by 2075, and a 98 per cent chance the population will suffer catestrophic losses by 2100, if climate change warms the water.

An international research team looked at the ability by the chinook to adapt to warming water temperatures caused by climate change.

UBC zoologist Anthony Farrell was part of the research group and says the juvenile salmon studied developed serious heart problems in water temperatures higher than 24.5 C.

Once past that temperature, the study found that the heart couldn’t go any faster and would either slow or go arrhythmic.

The study was recently published in the journal Nature Climate Change.
