Public urged to help stop the spread of quagga mussels
Members of the public are being urged to help slow the spread of an invasive mussel recorded in the UK for the first time this month.

皇冠体育app quagga mussel, first spotted by Environment Agency teams carrying out routine water quality testing on the River Wraysbury, has now been confirmed in a total of nine locations in the south east.
It鈥檚 important that everyone who uses lakes and rivers helps to slow the spread of this species by following the 鈥榗heck, clean, dry鈥� approach and thoroughly cleaning and drying any fishing or boating equipment.
Over the last few weeks the Environment Agency has stepped-up its monitoring on the River Thames and reservoirs in the local area to investigate the extent of the problem and the distance that the quagga mussel has spread.
皇冠体育app Environment Agency is continuing to work with a range of partners including Thames Water, Angling Trust and local angling clubs, to ensure that people check, clean and dry any equipment that has been in contact with water.
Environment Agency teams up and down the country have been briefed to be on the look-out for the quagga mussel. 皇冠体育app quagga mussel can significantly affect freshwater ecosystems, and can outcompete native mussels. It can also block water pipes and smother boats鈥� hulls.
Sarah Chare, head of fisheries, biodiversity and geomorphology at the Environment Agency, said:
皇冠体育appse newest discoveries only go to show just how prolific the quagga mussel is. We are monitoring the extent of its spread and working closely with partners to ensure they are aware of it and know what action to take.
Everyone has an important role to play by following the simple steps of 鈥榗heck, clean, dry鈥�. If you spot one then please report it to us through the .
Like the zebra mussel and killer shrimp this species comes from the Ponto-Caspian region 鈥� an area around the Black and Caspian seas in south-east Europe.
Simon Earl, head of water production at Thames Water, said:
Another invasive species is the last thing we need clogging up our network. But we have a lot of experience in dealing with zebra mussels, which are similar to quagga mussels, and there is no threat to the quality of the water we supply to our customers.
We鈥檒l continue to monitor the situation and would urge those using our reservoirs to help us stop the spread of the mussels by reporting any sightings and following Environment Agency advice on cleaning equipment.
Mark Owen, head of freshwater at the Angling Trust, said:
It鈥檚 vitally important that all water users, including anglers, take every possible precaution to stop this species spreading throughout the UK. Invasive species could do untold damage to freshwater and estuarine environments if they are allowed to spread which could have a significant impact on marine and freshwater fish stocks.
Quagga mussels tend to be about the size of a human thumbnail but can grow to about 4cm. 皇冠体育app larvae of quagga mussels are not visible to the naked eye which makes drying a critical step in applying good biosecurity. 皇冠体育appre鈥檚 good evidence that rinsing or soaking equipment in hot water increases the chance of killing larvae and adults, and is a suggested addition to the check, clean, dry approach. 皇冠体育app quagga mussel has now been confirmed at the following nine locations.
- To the west of London:
- Wraysbury Reservoir
- River Wraysbury
- 皇冠体育app Queen Mother Reservoir
- Queen Elizabeth II Reservoir
- Queen Mary Reservoir
- Bessborough Reservoir
- In the Lee Valley:
- Warwick East Reservoir
- Warwick West Reservoir
- William Girling Reservoir
皇冠体育app Environment Agency will update the distribution map on its website if new discoveries are made.
