Osbaston youngsters are cleaning up Monmouthshire's streams and rivers with the help of a little yellow fish.

The fish in question is being spray-painted near drains to help remind people not to pour away harmful oils and chemicals.

Youngsters from Osbaston School have been reading up on this form of pollution and last Thursday (18th October) they took to the streets to spread the message.

"People pour things down the drain that aren't very good for the environment because drains lead to streams and rivers, where a lot of animals and fish live, and it isn't good for them at all," said Joe Hughes-Gardiner, a member of the school's eco council.

Those caught polluting could face a fine of up to £50,000 and expensive clean-up costs, or even jail.

Pupils will be painting more yellow fishes in the coming weeks as well as putting up posters promoting the campaign, which is being run by Keep Wales Tidy.

Project co-ordinator Joanna Friedli said: "Water pollution is a huge problem in Wales and we are delighted that so many schools and community groups are addressing the issue and raising awareness in their local area through the Yellow Fish campaign.

"Let us know on Twitter (@keep_wales_tidy) or Facebook when you see a yellow fish in your neighbourhood."
