The Mallow Trout Anglers have issued a strong call for action following last month’s catastrophic fish kill on the River Blackwater, describing the lack of answers as “deeply troubling and unacceptable.”
Nearly a month on, no official cause has been identified and toxicology results have yet to be released. The club says speculation around natural causes such as low water levels, high temperatures or fungal infection has distracted from the possibility of human-related factors.
Early reports estimated 1,000 dead trout, later revised to 10,000. However, Mallow Trout Anglers believe the true figure is far higher, closer to 50,000 fish, many of them mature, wild trout. The kill has been recorded over a 30km stretch, from Banteer Bridge downstream to Killavullen. Contrary to some reports, the Clyda River has not been affected.
The club, which first reported the incident, says it is disappointed by the lack of communication from state bodies, despite assurances at a press meeting in Mallow on 22 August. “This silence leaves our members feeling ignored and undervalued,” the committee said, highlighting their century-long role as guardians of the river.
They warn that the disaster extends beyond angling, with fish forming a vital food source for otters, birds of prey and other wildlife. They are also calling for tougher penalties against serial polluters, including licence revocation and mandatory river restoration.
The club has outlined five immediate priorities: restoring fish stocks, protecting surviving populations, improving communication with local stakeholders, ensuring accountability, and enforcing stronger penalties for polluters.
“The River Blackwater is not just a resource—it is part of our heritage and ecosystem,” the statement concluded.
