A questionnaire survey of fishery proprietors was conducted to provide information on angling practices on key lochs within the Spey and Dee catchments. This was followed by netting, electro-fishing and angling surveys to discover whether of not non-native species were present within the lochs.

R. Laughton, A. Hudson and N. Sherwood: 2006

A previous survey using gill nets, angling and fish traps of lochs in Speyside and Deeside (Redgewell, Laughton and Hudson 2004) indicated the presence of non native species at a number of locations. This survey builds on the 2004 one by testing boat electro-fishing as an approach to assess open water areas. The boat electrofishing was trialled at five stillwater locations, Skating Pond (Grantown), Loch Beag, the Bogach, on Speyside and Loch Davan and Loch Kinord on Deeside. A trial was also conducted on a slow flowing reach of the Spey near the confluence with the River Nethy.
