CEV is a poxvirus which causes a disease known as ‘koi sleepy disease’ in both koi and common carp.
Mr Scully said in recent years, there have been a number of improvements made at the Lough, including two upgraded fountains, fish rinse bins for anglers to disinfect their equipment and introducing Barley straw in the spring/summer months.
He added that the area is being assessed for further improvements to lighting and surrounding footpaths.
The Head of Parks and Recreation also said the area was maintained to a high standard and called it one of the biggest used amenities in Cork.
“I go running down by the Lough three times a week and a huge amount of people go walking and running down around the area.
“When the sun is shining there are people throwing a frisbee, kicking a ball and playing hurling.”
