Captive breeding programme

Pearl MusselPearl Mussel

In September 2007 some of the Esk pearl mussels were relocated to a captive breeding facility in the Lake District.

The Esk mussels bred successfully in the Summer of 2008, 2011 and 2012.  In 2012 approximately 1,300 juveniles were collected but so far we have had no juveniles survive through to maturity.

It is hoped that juvenile mussels will be reared at the facility and can be re-introduced to the River Esk in around five to ten years time when the habitat in the River Esk has improved and the mussels are large enough for release into the wild.
