Taken from Derbyshire thread.
"From an email received today:
Rainbow Trout stocked into the Wye by Cressbrook and Litton Flyfishers have been caught exhibiting signs of disease, red raised marks on the flanks of the fish which otherwise appeared to be in very good condition.
Research on the internet indicates this may be a disease known as 'cold water strawberry disease', for more information see
http://www.thefishsite.com/articles/...wberry-disease.
This has been spreading through fish farms since 2003. Cressbrook and Litton Flyfishers have contacted the EA and they are going to electrofish the areas where the fish were caught as they have not heard of this disease in the wild before. They will then autopsy any diseased fish in order to make a firm diagnosis of the disease. The Cressbrook committee have decided to suspend further stocking with rainbows until we have further information on this disease, especially in view of the presence of breeding rainbows in the Wye."
