Automatic recording of fish heart rate on a personal computer
Original version
This report is not to be cited without prior reference to the authorsAbstract
From acoustic tags operated into fish in a closed system, the
heartbeat signals are sent via underwater telemetry and
counted on a personal computer. The computer removes false
pulses caused by noise, and calculates the heart rate for one
minute based on reliable heartbeats. Up to 6 fish can be
monitored in a sequence of one minute per fish. The heart
rate is stored on a file, or transferred to another computer.
