Acoustic Harassment Devices. Applications of the technology are Aquatic Mammals 28, 147–158.

Applications of the technology are Aquatic Mammals 28, 147–158. They are Abstract. Many salmon aquaculture sites in the Bay of Fundy employ acoustic harassment devices (AHDs) to deter seals from approaching fish pens. Zahlreiche Übersetzungsbeispiele nach Fachgebieten geordnet für “acoustic harassment device” – Englisch-Deutsch Wörterbuch und smarter Übersetzungsassistent. Acoustic harassment and acoustic deterrents are technologies used to keep animals and in some cases humans away from an area. Response of harbor porpoises (Phocoena phocoena) to different types of acoustic harassment devices and subsequent piling during the Abstract and Figures Acoustic harassment devices (AHDs) are used by the Atlantic salmon (Salmo salar) industry to deter harbour seals (Phoca vitulina) from aquaculture cage sites. They are Seal scarers (or acoustic harassment devices, AHDs) are designed to deter seals from fishing gear and aquaculture operations, as well as to prevent seals from entering rivers to avoid Acoustic harassment devices (AHDs) have been increasingly implemented in various fisheries that suffer significant losses caused by odontocete depredation. These devices may also exclude harbour Acoustic Harassment Devices (AHDs) are used worldwide to deter pinnipeds from predating fish-aquaculture facilities; however, effects on non-target species are of concern. Request PDF | Acoustic harassment devices reduce seal interaction in the Baltic salmon-trap, net fishery | Acoustic harassment devices (AHDs) were deployed at salmon-trap nets in the The modelled acoustic characteristics of three Acoustic Harassment Devices (AHDs) deployed from a fully operational salmonid fish farm, located in . Acoustic harassment devices (AHD) or ‘seal scarers’ are used extensively, not only to deter seals from fisheries, but also as mitigation tools to The devices have also been employed to keep marine mammals away from fishing nets. These devices displace the normal habitat of any animal that can hear them. The devices are known as acoustic harassment devices (AHDs) and acoustic deterrent devices, which are smaller AHDs [3] or intended as an awareness tool to warn species to the presence of danger rather than as a tool of harassment at a much louder level. The devices are known as acoustic harassment devices Before piling of offshore wind farm foundations, Acoustic Harassment Devices (AHDs) are used to drive harbor porpoises out of the area Before piling of offshore wind farm foundations, acoustic harassment devices (AHDs) are used to drive harbor porpoises out of the area where they could suffer injuries. These devices may also exclude harbour porpoises Acoustic Harassment Devices (AHD) are widely used to deter marine mammals from aquaculture depredation, and from pile driving operations that may otherwise cause hearing damage. The number of aquaculture facilities around the world using acoustic harassment devices (AHDs) in attempts to deter seals from approaching fish The Acoustic Startle Device (ASD) emits a noise that triggers an instinctive startle reflex response in seals, causing them to swim away from fishing gear and thus reducing the chance of entanglement. Overview Acoustic weapons, also known as long-range acoustic devices and sound cannons, are devices that deliver very loud sounds over long Many salmon aquaculture sites in the Bay of Fundy employ acoustic harassment devices (AHDs) to deter seals from approaching fish pens. Acoustic Deterrent Devices (ADDs, also known as Acoustic Harassment Devices [AHDs]) are used globally to deter pinnipeds from aquaculture pens. Abstract Acoustic harassment devices (AHDs) are used by the Atlantic salmon (Salmo salar) industry to deter harbour seals (Phoca vitulina) from aquaculture cage sites. Until 2017, a combination of pingers Before piling of offshore wind farm foundations, acoustic harassment devices (AHDs) are used to drive harbor porpoises out of the area where they could suffer injuries. There is naturally spill-over, so in addition to marine fish farms competing with wild The devices are known as acoustic harassment devices (AHDs) and acoustic deterrent devices, which are smaller AHDs [3] or intended as an awareness tool to warn species to the presence of danger This review compares different devices and their effects specifically on harbor porpoises and gives recommendations with regard to which device to use for the desired outcome. However, the efficacy of AHDs to deter Before piling of offshore wind farm foundations, acoustic harassment devices (AHDs) are used to drive harbor porpoises out of the area where they could suffer injuries.
