Salmon Ear Bones

MOSCOW, Idaho (AP) — Researchers at the University of Idaho are looking at the ear bones of salmon to help discover just how close the fish get to returning to the spawning beds where they emerged as fry. UI College of Natural Resources Associate Professor Brian Kennedy told the Lewiston Tribune the ear bones are made up of thin layers and a new layer gets added every day, similar to tree rings. The composition changes based on water temperature and chemistry.
