... mapping and fine-scale acoustic telemetry revealed movement paths that tracked thalweg scour channels, which are often the deepest and fastest-flowing sections of a river. These paths allow rapid and efficient upstream migration and suggest the existence of a bathymetric highway system. Near-substrate...

... landmarks in a familiar area cannot be discounted; i.e. site-specific fish are likely to use three-dimensional spatial memory for navigation and orientation. Using high-resolution acoustic telemetry, we investigated whether S. cheni exhibit distinctive homing paths. Results show that all of the eight...

...Heidi Dewar; Max Deffenbaugh; Gary Thurmond; Khosrow Lashkari; Barbara A. Block ABSTRACT We report the development of an acoustic telemetry tag used to monitor electromyograms (EMGs) remotely from free-swimming marine fish. The device described amplifies and filters the EMG and then converts...

...Francis G. Carey; John W. Kanwisher; E. Don Stevens ABSTRACT Acoustic telemetry showed that stomach temperature from large bluefin tuna, Thunnus thynnus , held in an impoundment, changes markedly during feeding. The stomach cools rapidly on ingesting cold food. It then warms to a maximum of 10–15...
