Evaluation of Satellite Tag Retention in Bigheaded Carp

GPS satellite technology provides real-time fish locations that can help manage invasive bigheaded carp populations. Species-specific satellite tags are effective at detecting fish. However, the best method of attachment and subsequent effects to the fish have not been evaluated. In addition, the nature of the tag prevents efficient recovery of tags, so the effects of adding an additional acoustic tag also need to be evaluated. To test improvements in tether design and the effects of adding an acoustic tag to satellite tagged fish, we set up an experimental pond design using 28 silver carp. We evaluated body condition (Wr), visual condition of the fish, and overall health effects associated with tag establishment on three treatments (n=7 each, satellite only, acoustic only, and dual satellite plus acoustic tag) and one control (n=7, no tags) in an experimental outdoor pond. Information from this study will lead to better informed decisions for future GPS satellite tag deployments.
