Largest fish kill of the year linked to very high temperatures

A severe algal bloom and very high water temperatures are likely to have caused the fish kill in Co Cavan. 

The largest fish kill of the year has been linked to “very high” water temperatures recorded during the recent heatwave.

Inland Fisheries Ireland (IFI) estimates in excess of 5,000 fish may have died in the fish kill incident at Barnagrow Lake in Co Cavan.
