Eda Ranu managing director, Henry Mokono, said it’s been a common practise and wants it to stop.
He made the comments during the commissioning of the Sewerage Treatment Facility at Morata.
Mokono said the treatment facility contained toxic waste by-products which are poisonous and harmful, making the fish inedible.
He added some of the fish were also sold at markets or on the street.
“The fish in here they are not safe to eat. Although we got thousands of fish right now in that secondary pond, I’m told that all the waste is too much.
