Sockeye and summer chinook salmon with either floy tags or holes punched in their tails should not be kept or consumed, says the Washington State Department of Fish and Wildlife.
The markings are indications that fish in the Columbia River and its tributaries from Priest Rapids Dam upstream to Chief Joseph Dam have been anesthetized during various studies.
Floy tags look like the plastic tags with a T on one end used to attach price tags to clothing. The holes punched in tails are about a quarter inch in diameter.
