Fish heart rate telemetry in the open sea using sector scanning sonar.
Real time monitoring of heart rate from free-swimming fish in the open sea has been used in conjunction with high resolution sonar to track plaice and observed the variation in heart rate in relation to environmental parameters. The heart rate can be observed at the same time as the acoustic picture of the sea bed or the midwater volume of sea surrounding the fish.
