A mobile system incorporating a novel transmitter for tracking the position of freshwater fish is described. The transmitter emits both acoustic and radio pulses simultaneously to allow a range estimate from the delay between signals arriving at a receiver station. Results of field trials are presented and the usefulness of the system is discussed in relation to other tracking methods.
