The grayling is a common heathland butterfly.
Like all salmonids the grayling has a small adipose fin behind the dorsal fin.
The grayling butterfly also attracts lurking predators by displaying the eye-spots, but at the same time diverts their attention to the unimportant parts of their body.
Most species of river fish will be surveyed including trout, grayling , dace, barbel, chub and pike.
By carrying out the project we hope to attract fish, such as chub, dace, grayling and trout as well as other wildlife back to this particular stretch of river.
