Inland Fisheries Ireland has confirmed to Northern Sound this evening that it is continuing investigations into a fish kill on Lough Sheelin at the weekend.
The State agency is describing the incident - which resulted in the death of over 1,000 fish on the Crover River - as "significant".
It indicated how it learned of the matter after officers from the Shannon River Basin District were alerted on Friday last.
Inland Fisheries Ireland estimates in excess of 1,000 juvenile trout were killed in the incident which covers a 1.5km stretch of water.
Aquatic species including ray fish, lamprey, stone loach and invertebrates also died.
Inland Fisheries Ireland also pointed out that it is not yet in a position to confirm the cause of the fish kill.
"While investigations into this fish kill incident are ongoing, Inland Fisheries Ireland is not in a position to confirm the cause of the fish kill," a spokesperson added.
"To report fish kills or water pollution, members of the public are encouraged to call the confidential 24-hour hotline number on 0818 34 74 24, which is open seven days a week."
