whether there are plans to control or eradicate North American signal crayfish in (a) Lochrutton and (b) the Lochfoot Burn in Dumfriesshir…

I am advised by Scottish Natural Heritage that they have not yet identified an effective method for the eradication of North American signal crayfish in water bodies such as Lochrutton and the Lochfoot Burn, albeit this is an objective the Scottish Government is keen to pursue if at all possible.
The Fisheries Trusts and Scottish Environment Protection Agency (SEPA) are working together to raise awareness of appropriate biosecurity measures that water users can take to avoid spreading the species, and other freshwater invasive species, to other parts of the catchment or to other parts of Scotland. This includes launching a number of biosecurity campaigns across Dumfries and Galloway this spring and summer to raise awareness of invasive non-native species, including the Check Clean Dry and Be Plant Wise initiatives across the region. All campaigns are being co-ordinated by SEPA with support from a variety of partner organisations such as Police Scotland, the Galloway Fisheries Trust, the Nith Catchment Fishery Trust, the River Annan Trust, Dumfries and Galloway Council Ranger Service, Solway Firth Partnership and Scottish Natural Heritage. These campaigns will be supported by the distribution of thousands of leaflets, identification guides, posters and signs across the region.
