<br />Theoretical and applied information about radiotelemetry related to rivers with high
<br />conductivity is presented in this report. Theoretical information is presented in
<br />a simplified form for investigators new to the radiotelemetry field. Radiotelemetry
<br />and ultrasonics are compared as methods for obtaining information about fish movements
<br />in turbulent, turbid river systems. Results from field studies were used to evaluate
<br />the reception of radio transmissions from fish under natural conditions.
