Details

Recent recovery in otter numbers has led to conflict with inland freshwater fisheries in some areas. A suggested alternative to fencing is the use of acoustic deterrents or ‘pingers’ similar to those used to keep porpoises and dolphins away from fishing nets. This report presents the results of preliminary investigations by the Environment Agency and Oxford University to assess the potential for pingers to be used as a management tool to reduce otter predation of fish in stillwater fisheries.
