Fish restocked in Norfolk and Bedfordshire rivers after pollution incident
Thousands of fish have been released into rivers as part of a "recovery plan" following a pollution incident more than three years ago.
The Environment Agency (EA) said 17,400 one to two-year-old fish were released across Norfolk and Bedfordshire waters.
In total, 15,000 fish were added to the River Thet in Norfolk, to be restocked after a pollution incident in 2018.
Hundreds of died when polluted surface water was released by a burst water main, in Raymond Street, Thetford.
Kye Jerrom, a fisheries specialist for EA, said: "The fish restocking is linked to fish deaths caused by a pollution incident in July 2018.
"We have also enhanced wildlife habitats on that section of river to allow fish better access through the catchment for feeding and spawning. These include a fish pass at Brandon and a bypass channel in Thetford."
The fish that were added to the River Thet, included 5,000 chub, 5,000 dace and 5,000 roach.
Blue dye
A further 1,412 barbel went into the River Ivel at Biggleswade Mill and Blunham weir.
Twelve of the barbel were given blue dye marks on their stomach, so they can be identified and evaluated to see how successful the stocking has been.
Anglers have been encouraged to take a picture of the marked fish, weigh them, and get in touch, with the EA.
Mr Jerrom said: "Our aim is to create a river that can manage natural predators and support angling.
"Every penny made from fishing licence income is spent on making improvements to rivers to benefit anglers."
About 1,000 crucian carp were also distributed between two fisheries in Norfolk and Buckinghamshire, the agency added.
