Ayrshire Rivers Trust will very shortly have an additional licenced Freshwater Pearl Mussel (FWPM) surveyor in the team. Muir attended a freshwater pearl mussel training workshop yesterday in Inverness hosted by Scottish Natural Heritage (SNH), The Scottish Fisheries Co-Ordination Centre (SFCC) and Ness and Beauly Fisheries Trust. The aim of the workshop was to introduce surveyors to FWPM surveys, ecology and conservation. It was an informative day providing attendees with the latest up to date survey techniques and learning of the latest research first hand from experienced experts in FWPM conservation.
Here in Ayrshire, the Trust has a long history of surveying and representing FWPM’s interests. Our unique position where we work for District Salmon Fishery Boards, riparian owners and undertake FWPM surveys for developers and consultants means we have built up extensive knowledge on their distribution in Ayrshire. However, there may be populations that remain undiscovered within watercourses that have never been surveyed. It is likely that most Ayrshire Rivers would once have had a freshwater pearl mussel population but many of these populations have either declined or disappeared due to human activities. These include pollution, river engineering, acidification and declining salmonid stocks which the mussel uses as a host during the larval stage.
The freshwater pearl mussel is fully protected by law under Schedule 5 of the Wildlife and Countryside Act 1981 (as amended) and it is a crime to intentionally or recklessly kill, injure, take or disturb pearl mussels or to damage their habitat. It’s also an offence to possess or control a living or dead FWPM or sell, offer for sale, or possess or transport for the purpose of sale any living or dead FWPM. If you see a living or dead FWPM on the river then report it to the Trust. Do not touch or remove the mussel even if the shell is empty.
If you are planning river engineering works, you should ensure that your plans will not have a negative impact on freshwater pearl mussels. Failure to do so may mean that you are breaking the law.
