One fish at a time is collected.

 The nose of the fingerling is held against a devise that will insert a coded wire tag. After the fingerlings receive a fin clip and coded wire tag, they are released back into the cement raceway. This coded wire tagging unit safely inserts a wire tag into the noise. Each tag contains descriptive marks that can identify each group of fish.
