CRIMP Monitoring Started

Hi

Following the recent training of six of its members, the UAAA had its first sampling outing on the upper reaches of the Avon and its tributaries. They were joined by Lesley Gregg who is a biologist with the Clyde River Foundation based at the University of Glasgow. It was a fine day and although most of us were struggling to remember the difference between a blue-winged and a regular olive, with a bit of help from Lesley we were soon back up to speed and huddled round the tray counting the different types of invertebrates and recording the data. The number of larvae in the river is amazing to see, with several hundred swimming around in each sample tray. The big Stoneflies are particularly impressive with some of them over 30mm long!

The data from each site will be monitored on an ongoing basis and combined with data from other angling clubs across the Clyde catchment. This should help build up a good indication of the health of the river. If any member would like to help out with future monitoring please get in touch with the River Manager – All welcome, no experience necessary!

Many thanks again to Wullie, Tommy, Andrew, Graeme and Lesley.
