Investigation into ‘major fish kill’ after pollution incident
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.
In short
- Pollution killed trout across three County Down rivers.
- Anglers estimate about 1,000 fish died.
- Authorities are investigating the source and impact.
Explained simply
Rivers in County Down support brown trout and sea trout, which are trout that migrate between rivers and the sea. Fish can be harmed or killed when pollutants enter the water, and pollution can also affect other wildlife and the wider river habitat.
The Northern Ireland Environment Agency investigates environmental pollution, while Daera Inland Fisheries oversees inland fisheries. Angling clubs represent people who fish locally and often monitor river conditions; the Inler Angling Club says these rivers have experienced fish deaths before.
The scale and source of a pollution incident can take time to establish. Repeated harm to a river may affect fish stocks and the wildlife that depends on the water.
