October 04, Colombo (LNW): A large number of fisher families living near the Deduru Oya reservoir in Kurunegala district have raised concerns about the presence of poisonous giant fish species that are posing a threat to other aquatic life in the reservoir. These venomous fish species, identified as snake-headed stone fish, are reportedly harming local fish populations, severely impacting those engaged in the inland fishing industry.
A recent survey confirmed that these snake-headed fish species are dangerous, with experts warning that they threaten other fish and aquatic creatures. The species, commonly known as Gonmaha stone fish, are typically found in shallow waters, sandy areas, lagoons, and lakes, according to Senior Lecturer Dr. Janaka Ruben from the Faculty of Medicine at Ruhuna University. The fish are known to be venomous and can even pose risks to humans.
Ranjith Sumanasiri, a representative of the Daduru Oya Fishermen Association (DFA), told the that the venomous fish have been spotted in the Deduru Oya lake and are causing a significant reduction in fish populations. He reported that approximately 70% of the reservoir’s fish are rapidly disappearing due to the invasion of these dangerous species, creating a serious threat to the livelihoods of the local fishermen.
Sumanasiri urged authorities to address the issue urgently, calling for immediate measures to control the spread of these snake-headed fish and protect both the ecosystem of Deduru Oya and the fishing community that depends on it.
