Project 2007-160-00 - Evaluation of spawning success in Pacific salmon using electromyogram telemetry
Evaluation of spawning success in Pacific salmon using electromyogram telemetry
Summary:
We propose to implant sockeye salmon with electromyogram transmitters to determine when and how frequently they spawn, and to investigate differences in spawning among groups of fish exposed to different rearing conditions naturally migrating fish
Proposer:
None
Proponent Org:
Pacific Northwest National Laboratory (Govt - Federal)
This proposal offers an innovative technological approach to studying salmon reproduction. The technique may provide some excellent data on the bioenergetics of the spawning act, and the proponents have expertise in the area electromyogram telemetry. However, the ISRP had difficulties envisioning how the data would be beneficial to fish and wildlife and how the project ties in with subbasin design and objectives. The literature review for the proposal was not thorough and did not include the many examples of the effects of hatchery culture on the timing of the spawning. Given the rarity of these fish, the ISRP also had some concerns that the transmitters might have effects on the health and well being of the sockeye. Finally, the ISRP has recommended "not fundable" for the set of ongoing Redfish Lake sockeye captive rearing projects because of the lack of success of this method for conserving the population.
