## Summary

An investigation is under way after pollution killed brown and migratory sea trout in the Gransha, Ballystockart and Inler Rivers in County Down. The incident has been described as a “major fish kill”; anglers say it could damage fish stocks and other wildlife, and have called for stronger protection of rivers.

The Department for Agriculture, Environment and Rural Affairs said a member of the public reported the incident at 09:30 GMT on Tuesday. The Inler Angling Club estimates about 1,000 fish died, but the Northern Ireland Environment Agency and Daera Inland Fisheries are still establishing the source of the pollution and the final death toll. The club says the river was still recovering from earlier fish kills in 2013 and 2015.
