More than 300 fish have been released into the River Medway in Maidstone - complete with their own design of tattoo.

The unique inkings are so their progress can be monitored.

The fish have been released at Barming as part of a joint initiative between Maidstone Victory Angling Society and the Environment Agency.

The club bought the barbel and chub from Riverfield Fish Farm before they were marked with a harmless dye.

Anglers who catch them in the future can submit their details, including date, weight, location, and size to the agency before releasing them back.

The information will then be assessed to see how well they are growing in the Medway; their migration and dispersal, and to check to see whether the quality of the river is suitable for healthy fish growth and population.

Joe Kitanosono, fisheries officer at the Environment Agency, said: “This is an excellent example of the Environment Agency working in partnership with an angling group to assess fisheries stocks in the River Medway.

“This initiative will allow the Environment Agency to determine if there are any underlying issues preventing the fish from healthy growth and dispersal, as we want to improve fish stocks and provide a better environment for wildlife and people.”

Anglers can report details of tattooed fish they catch to Joe on Twitter @JoeFishingEA, by emailing joe.kitanosono@environment-agency.gov.uk or by calling 011732223176.
