Fish to be relocated from Kennet and Avon canal
More than half a tonne of fish is being removed from a section of the Kennet and Avon Canal as part of a "habitat enhancement project".
British Waterways want to improve the environment at the Caen Hill Flight of Locks near Devizes for scarce aquatic plants and invertebrates.
Large fish are being removed from the side ponds of the famous lock flight.
The relocation will see less silt disturbed, enhancing water quality and limiting predation of smaller fish.
British Waterways' ecologist Oda Dijksterhuis said: "The fish relocations happening this week will help to improve the habitat of the other ponds on the flight, so hopefully we'll see more plants and invertebrates appear in the coming months around all of Caen Hill's ponds."
A trial project in 2009 saw a tonne of fish, including large tench, carp, bream, roach, perch and pike removed from the ponds.
"We take great care of the fish throughout every part of the process and local anglers will welcome the release of some of these larger fish into the canal," said John Ellis, fisheries manager for British Waterways.
