Tests show no signs of ISA virus in Washington’s salmon

A joint press release from the Washington Department of Fish and Wildlife, western Washington Treaty Tribes, and the US Fish and Wildlife Service on ISA monitoring results:

Recent tests of salmon from Washington’s waters show no signs of a fish virus that can be deadly to farm-raised Atlantic salmon, state, tribal and federal resource managers announced today.

Infectious Salmon Anemia Virus (ISAV) was not detected in tissue samples taken from more than 900 wild and hatchery-produced Pacific chinook, coho, sockeye, chum and steelhead, as well as farm-raised Atlantic salmon.

ISAV is not harmful to people.

Bruce Stewart, Fish Health Program manager for the Northwest Indian Fisheries Commission, said the sampling and monitoring program is a great example of tribal, state and federal managers working together to address concerns about the health of salmon and steelhead stocks in Washington.

“While this first year’s results are encouraging, we hope to increase our level of confidence that the virus is not present in Washington by continuing our efforts and including testing of pink salmon,” said Stewart, who noted that most pink salmon return to Washington’s waters only in odd-numbered years.
