Virus causing salmon deaths?
By ROB HOTAKAINEN; Staff writer
WASHINGTON – In Canada’s Fraser River, a mysterious illness has killed millions of Pacific salmon, and scientists have a new hypothesis about why: The wild salmon are suffering from viral infections similar to those linked to some forms of leukemia and lymphoma.
For 60 years before the early 1990s, an average of nearly 8 million wild salmon returned from the Pacific Ocean to the Fraser River each year to spawn.
Now the salmon industry is in a state of collapse, with mortality rates ranging from 40 percent to 95 percent.
