A young swan died after swallowing fishing hook and line that had been discarded in a river.

Lesley Martin, who lives near the River Frome in Dorchester, found the cygnet in the Mill Stream, near Caters Place, on Sunday evening and discovered it had ingested a discarded fish hook and tackle. 

She alerted wildlife rescuer Derek Davey who tried to rescue the cygnet but unfortunately it died of its injuries.

She said: "We’ve had a family of seven cygnets with their parents living on the bank in Mill Stream.

"I saw one of the cygnets in deep distress, drowning. It was covered in fishing tackle with a hook down its throat.

"It's so sad to see a beautiful cygnet dead in the water, because people have inconsiderately left stuff in the river.

"We’ve got to make people aware that people can’t just discard their equipment in the river as it’s a risk to wildlife."

Having lived in Dorchester for 40 years, Mrs Martin says the area has always been hazardous for birds.

Now Mrs Martin wishes to highlight how discarded fishing litter poses another major risk for swans and cygnets.

She added: "It's just awful - everybody should know about this.

"We've got to make people aware that you can't fish here and leave your equipment for swans to suffer and get killed."

He described the situation as "out of control" and called for a ban on fishing in that part of the river.

He said: "It's ongoing around there and it's just ridiculous.

"It's mostly young fishermen and they just don't care. We've tried to talk to them and we just get abuse. 

"Hooks are being left on the sidewalks and children play around there. It's just not safe. 

“There needs to be a ban on fishing near that river walk or it will never stop."
