HPT8 Minichip tags purchased from Biomark last month. A slender 8 mm tag with limited read range. We will be applying these tags to juvenile Chinook salmon in the upper McKenzie River basin to study instream growth and survival through repeated capture in the same areas. A few of these tags may be detected at the Leaburg PIT antennae.
A hatchery study was done on the size of juvenile Chinook that could be tagged and growth rates when compared to 12 mm PIT tags. We have not yet tested detection efficiency at the Leaburg or Willamette Falls.
