Fish returning to Yorkshire's clean rivers
Improvements have been made to water quality and over the past year the Environment Agency has been working with partners to build more than 10 new fish passes in an effort to see the return of salmon, sea trout, lamprey and eel. The passes allow fish to negotiate blockages, such as weirs.
One of the latest fish passes to be completed is on the River Don, on the outskirts of Sheffield, and Neil Trudgill of the agency said: "Initial surveys of fish in the river around the pass show the continued recovery of brown trout, grayling, chub, and dace."
