Synopsis

A range of small, long-life ultrasonic fish tags is described and their use illustrated with an improved system of fixed hydrophone tracking stations. A boat-mounted hydrophone system giving bearing and range estimations for use in open-water fish tracking is described together with a portable handheld unit for simple location of tagged fish in rivers, etc. Typical results based on intensive use of these systems are given.
