THE EFFECTS OF ACOUSTIC ALARMS ON THE BEHAVIOR OF HARBOR PORPOISES ( PHOCOENA PHOCOENA) IN A FLOATING PEN
A bstract In an attempt to test the effectiveness of sounds in deterring harbor porpoises from nets and reducing porpoise bycatch in gill net fisheries, two harbor porpoises, kept in a large floating pen at Neeltje Jans, The Netherlands, were subjected to 3 different underwater sounds. The effect of...

The standard Dukane alarm and the bird alarm were more effective than the random Dukane alarm in inducing the animals to swim away from the sound source.
