At least five people have been killed by hippos around Lake Naivasha in the past two months.
The killings have raised fear and anxiety around the troubled water body.
The latest killing was of a fisherman in Kamere landing beach along Moi South Lake Road on Tuesday evening .
The fisherman was killed by a lone hippo.
Encroachment of riparian land and closure of wildlife corridors have been blamed for the rising cases of human-wildlife conflict.
Lake Naivasha and Oloidien Boat Owners Association chairperson Grace Nyambura said the most affected are illegal fishermen.
She said there is an upsurge in the number of illegal fishermen, uncontrolled population of hippos and encroachment of the riparian land.
Friends of Lake Naivasha chairman said more than 50 per cent of riparian land around the lake had either been fenced or cultivated.
He said this had reduced pasture grounds for hippos, buffaloes and antelopes leading to human-wildlife conflict.
“The number of hippos around the lake has in the past five years tripled causing them to raid farms and attack members of the public,” he said.
Earlier, the Wildlife Research and Training Institute described the multiplying number of hippos in Lake Naivasha as ‘healthy’ despite rising cases of attacks.
The research institute said a census conducted last year indicated that the lake had more than 500 hippos.
