Of the 147 fish captured, 104 were implanted with a 12-mm Passive Integrated Transponder (PIT) tag. Small computer chips in these tags identify individual fish throughout their life span, with the use of a detector. We are quite curious whether some of these tagged fish will be detected entering the new Selective Water Withdrawal fish passage facility at Round Butte Dam next spring. We will have an automatic detector there.
