Abstract
Acoustic alarms, otherwise known as beacons or pingers, are designed to transmit certain sound patterns underwater as a deterrent effect on cetaceans in the vicinity of fishing nets. The device presented here has been successfully tested in Scotland and Denmark and has been shown to reduce the by-catch of harbour porpoises during a commercial fishing trial
