The rising water level in Lake Victoria has disrupted fishing activities across counties bordering the water resource, undermining production.
The backflow has also displaced fishermen from landing sites and beaches, which have been covered by water.
Homa Bay County Beach Management Units chairman Edward Oremo said many fishermen have abandoned fishing because of reduced catches.
In Homa Bay, fishermen estimate losing more than Sh300 million in fish sales amid the devastating effects of the rising waters, beach managers said.
Landing sites have been swallowed up by the lake water and fishermen now must anchor their boats using heavy rocks, said Moses Oulu, who has operated two fishing boats on Mageta Island in Siaya for seven years.
