Environment Agency Wales has identified the source responsible for killing more than 100 native crayfish and other species such as bullhead in the River Ennig at Talgarth, Powys on Wednesday.

The Agency confirmed that the source has now stopped and that there is no further risk to the environment.

Its officers will continue to assess a three kilometre stretch of the river over the next few days.

Holly Sisley, Environment Agency Wales said: 'Our officers acted swiftly to identify the source responsible for killing the crayfish. We are still awaiting the results from water samples taken at the River Ennig but can confirm that the source has stopped and poses no further threat to the environment.'

The dead crayfish were reported to the Agency on Wednesday afternoon by a member of the public in Talgarth.

Appeal after 100 crayfish found dead

Environment Agency Wales is appealing for information after more than 100 native crayfish, as well as other species such as bullhead, were found dead in the River Ennig at Talgarth, Powys on Wednesday.

The dead crayfish were reported to the Agency on Wednesday afternoon by a member of the public in Talgarth.

Investigations found the dead crayfish over a 2km stretch of the river in the Talgarth area.

Agency officers have taken samples from the river and are carrying out further investigations this week

Officers are appealing for anyone who has any information about the deaths or any pollution incident to come forward.

Holly Sisley, Environment Agency Wales, said:

"We are continuing to investigate these deaths in the River Ennig. Early tests have not shown unusually low levels of dissolved oxygen in the water so we are still trying to find the cause.

"This is especially disappointing as these native crayfish are already under threat from their non-native American cousins and we are working hard with our partners to protect and improve the population through a breeding programme.

"If anyone has any information about these deaths or any pollution please call our Incident Hotline on 0800 80 70 60."
