“Atlantic salmon have been confirmed as breeding in the River Don for the first time in more than two centuries.

The Don Catchment Rivers Trust (DCRT) said discovering a wild-born salmon in the river was the first evidence of successful spawning since they were wiped out by pollution and man-made barriers in the 18th and 19th Centuries.

It follows more than two decades of installing fish passes to reconnect the river, allowing salmon to return.”
