Natural Resources Wales (NRW) says more than 1,000 native white-clawed crayfish have been released into a Welsh river as part of continued efforts to save the species from extinction.

It's the third year NRW officers have captive reared and released the juvenile crayfish working in conjunction with the Wye and Usk Foundation.

The one-year-old crayfish were reared at Natural Resources Wales Cynrig Fish Culture Unit and have been released into specially selected ‘ark’ sites on a tributary of the River Irfon, near Builth Wells.

NRW says to date more than 2,700 captive reared crayfish have been released into the wild in a bid to offset the damage caused by the non-native American signal crayfish, climate change and the impact of pollution on habitat and water quality to the native crayfish population.
