Author(s): Dylan A Gravenhof*, Hilary A Morey, Cameron W Goble, Mark J Fincel and Jacob L Davis
Little is known about Gizzard Shad Dorosoma cepedianum life history and habitat use near the far northern edge of their native range. In 2016, the South Dakota Department of Game, Fish, and Parks aspired to implement an acoustic telemetry study to take a more in-depth look at Gizzard Shad movements and habitat use. However, adult Gizzard Shad have never been surgically implanted with telemetry tags. The objectives of this study were to determine if Gizzard Shad can survive surgery and handling, assess short-term survival and tag retention after surgery and determine what factors affect survival of tagged adult Gizzard Shad. Forty adult Gizzard Shad were surgically implanted with VemcoV13 dummy tags and 40 control fish were placed in a floating net pen. Survival of control fish averaged 90% and survival of tagged fish averaged 88% during the study. With a relatively small samp.. View More»
