KWANIA, UGANDA: Authorities in Kwania District have issued a health alert following a mysterious mass fish death in Lake Kwania, raising fears of possible poisoning and triggering widespread economic disruption.
Dead and weakened fish have been reported across all 11 landing sites along the lake, forcing an immediate halt to fishing activities and sparking panic among communities that depend on the lake for survival.
District officials have launched investigations into the cause of the die-off and warned residents against consuming or selling the affected fish.
“We suspect possible poisoning, but we must wait for scientific confirmation,” said Kwania LC5 Chairperson Geoffrey Ogwal Adyebo.
He issued a strong caution to the public: “Do not sell or consume any dead fish. This is a serious health hazard, and anyone found doing so will face the law.”
Leaders of Beach Management Committees described the situation as unprecedented, with the scale of the die-off pointing to a serious environmental threat.
At Atuma Landing Site, Chairperson David Odongo said the incident has shaken the community. “We have never witnessed anything like this. Fish are floating dead, and others are too weak to survive,” he said.
From Abei Landing Site, Walter Odongo reported a complete collapse in trade. “Fishing has stopped. Traders have fled because no one is willing to buy fish whose safety is unknown,” he said.

At Abali Landing Site, concerns have shifted to survival. “This lake is our only source of income. If this continues, families will go hungry,” said Odyek Peter.
Other landing site leaders warned that the problem is widespread, affecting the entire lake and heightening fears of contamination.
When contacted, Kwania District Production and Marketing Officer George Johnson Ojok Ocen said technical teams are already on the ground collecting water and fish samples for laboratory analysis.
“We are investigating multiple possibilities, including chemical contamination, oxygen depletion, or disease,” he said.
He added that poisoning remains a key line of inquiry. “We appeal to the public to remain calm but alert, and to report any suspicious activities around the lake,” Ojok said.
The incident has paralysed trade across the district, with traders avoiding landing sites and consumers rejecting fish products from the lake.
Local leaders warn that prolonged uncertainty could devastate household incomes and destabilise the local economy. “Fishing sustains thousands of households here. If confidence in our fish is lost, the impact will be severe,” Adyebo said.
Authorities say public safety remains the top priority as investigations continue. “For now, the message is clear—do not touch, sell, or eat the affected fish,” Ojok emphasised.
