Mobile tracking provides information on the rate and depth of movement for individual fishes. Results of this study are used to determine the effects of gas supersaturated conditions on the physiological performance of fishes. All fungi at each site are located and mapped by measuring the distance and azimuth from permanent benchmarks identified with coordinates from a GPS receiver. The receivers enable researchers to periodically return to benchmarks. Attributes are either logged at the time positions are collected or appended to the coordinates later.
Commercial software is used to perform coordinate transformations.
This study, funded by the Bonneville Power Administration, uses mobile tracking via boats to locate fishes fitted with transmitters. Results of this work are used to define the seasonal movements and microhabitats used by adult and subadult white sturgeons.
