Environment Agency officers have released 2000 trout fry (baby trout) into a tributary of the River Churnet.
The re-stocking follows a pollution incident two years ago, which resulted in a substantial loss of trout and coarse fish. Around 6,000 trout will have been re-stocked into the Rivers Churnet and Tean when the operation is completed.
Fisheries Officer, Mick Buxton, said: “Pollution incidents have a major impact on fish populations and the small aquatic life they feed on. The re-stocking exercise is part of our role to ensure that fish populations thrive into the future.”
