Olfactory Recording from Free Swimming Steelhead Trout

Steelhead trout, a variety of rainbow trout, are prized recreational  fish.  Exactly what draws them to their native streams to spawn  remains a mystery, but knowing these factors could help fishery  biologists better manage this migrating species.  Researchers plan  to build upon a previous Sea Grant study to develop a remote  telemetry system that will allow them to continuously record  impulses from nerves in the nose (olfactory nerves) of free-swimming  steelhead trout in a lab setting.  An electrode will be implanted  into the olfactory nerve of several steelhead trout.  Impulses from  the regenerated nerve will be matched to different scents that the  fish are exposed to and their associated behaviors.  Eventually,  researchers hope to use this technology in natural aquatic habitats  to determine which cues are important to steelhead during stream  migration.
