Fishermen have voiced their concerns after dead fish were found floating in a lake at Colwick Country Park over recent days.
Mick Farrell was one of the fishermen to highlight the issue.
He posted a number of pictures on Facebook after spotting the fish floating on the surface of the lake at the park.
He said:”I’m gutted by what I’ve seen today. There are fish struggling all over.”
Andrew Blake is also a regular fisherman at the site and lives nearby in Netherfield.
He said he was worried by what he saw.
“No idea what’s causing it. I guess it could be low oxygen. It’s not good. Let’s hope it’s not pollution or anything.
“It’s great to fish here and I normally do ok so it would be a shame to see numbers decline. Let’s hope they can sort it out.”
A spokesman for the park posted on their Facebook page after concerns were raised by visitors.
They wrote: “Thank you to those that have reported sightings of dead fish at the main lake. We are aware of the issue and are liaising with the Environment Agency.
