Inland Fisheries Ireland (IFI) has said that “no evidence of bacterial infection or systemic disease” has been identified in preliminary testing of samples taken from a large-scale fish kill under investigation in the river Blackwater.

The IFI statement came after the Marine Institute reported its preliminary test results of samples of the dead fish to IFI, Minister of State for Fisheries Timmy Dooley and the Environmental Protection Agency (EPA).

Initial water quality test results carried out by the EPA “do not raise concern” and further results “will be available in due course,” IFI said.

Investigations continue into the cause of an estimated 10,000 fish deaths along the Blackwater over a stretch of the river extending 12km upstream and 6km downstream from Mallow, Co Cork.

Further testing of samples for viral disease will be available “towards the end of August”, IFI’s statement continued.

“Testing to date also indicate the lesions observed are likely to be associated with an environmental irritant.”

IFI’s CEO Suzanne Campion thanked local anglers and the public for providing information to assist with investigations into the cause of the incident

Campion stated that any information IFI receives regarding the incident will be shared with the public.

“IFI welcomes today’s constructive engagement and collaboration with angler groups,” she said on Friday.

“We share their deep concerns over the very large number of fish mortalities on the Blackwater.

“At today’s meeting we assured representatives of IFI’s commitment to progressing our investigations, and our work with other statutory agencies on the matter.”
