A brand new device to keep dolphins clear of fishing nets is proving, quite literally, a resounding success. Developed by the Dutch company SaveWave, the Dolphin Saver is a sophisticated transmitter just 20 cm long that is attached to the nets. As soon as it touches water, the device emits harmless ultrasonic signals that interfere with the echo-location system used by the dolphins to navigate and find fish. Confused by the resulting ultrasonic jumble, the dolphins turn away, leaving a safe area around the nets. Not only does the device save the mammals from certain death as bycatch, it also prevents them stealing fish from the nets and damaging fishing gear, thus greatly improving catch levels and the overall productivity of fishing fleets. http://www.savewave.nl www.savewave.nl.
