PostSubject: American crayfish destroying Britain’s footpaths   Sun Feb 13, 2011 3:57 pm

American crayfish are destroying Britain's footpaths by burying into riverbanks and riddling them with holes "like Swiss cheese", environmentalists have warned.



Now British Waterways has started a £250,000 project to seal banks with plastic in a bid to stop canal sides from collapsing.

Signal crayfish, which have flourished after being imported from the US and escaping to breed in the wild, are already controversial because they have killed off the bulk of native, much smaller, freshwater crayfish over the last ten years through the spread of disease.

Now they are attacking the earth sides of canals putting footpath users at risk.

David Berezynskyj, senior engineer with British Waterways, said: "We need to act to avoid any serious damage and reduce the risk of the embankment breaching."

British Waterways, who look after 2,200 miles of the country's canals and rivers, are weaving sheets of a strong, plastic-like material called polypropylene into the canal banks, which they say is more attractive than using steel supports to keep out the creatures.

The ten-week project will see the canal bank along several sections in Newbury repaired and stabilised to prevent its collapse.

It has been criticised by the Civil Service Angling Society who support the use of crayfish catchers to control numbers.

Stephen Haines makes a living catching the shellfish on the River Kennet and the adjoining Kennet and Avon Canal at Newbury, Berkshire and said he offered his services for free.

A spokesman for the Civil Service Angling Association, which controls fishing rights on a stretch of river and canal at Newbury, said they would continue to allow Mr Haines to trap crayfish.

"We can clearly see that Stephen's trapping has limited the number of crayfish" said the spokesman.

However, British Waterways claimed otters, endangered water voles and other wildlife are at risk of getting caught in crayfish traps while disease carried by the American species could be spread by the wire cages being lifted from one place and planted in a different stretch of water.

A campaign has been launched to catch and kill the American crayfish and in some places the British species stage a comeback.

On one three-mile stretch of the River Kennet in Berkshire, one of the world's most famous trout fishing streams, keepers are reported to have caught and removed 20,000 American crayfish in one year.

I fish all of the bits mentioned and imo the trapping seems to have made little or no difference to numbers ,Also commercial trappers are known to put small ones back as there is no market for them plus it keeps there scource of Crays going .
They trap them in big numbers where the Oxford canal enters the Thames but again dont seem to make much difference there either ,just my take on it mind Steve.

I was a Civil Service member a few years back and met the fella trapping them on the Kennet. He had a big tubs of them but as you say does make little difference.

If the smaller ones are being returned then they are doing that yes beacuse not viable to sell but also does keep the population going.

At the end of the day Crays, like the Mittens, are an invasive species and should be eradicated from the river systems. Sadly to little action has ever been taken so hence where we are now.

do we really want our canal/river banks sealed in plastic

surely the damage that will do is immeasurable

make it illegal to return any crayfish, muller those that do, and allow concerned individuals to act in unison and trap'em

maybe something else for the ATr to get involved in

James i thought it was illegal to put them back ? ,Just dont see how they/we are going to get rid of now short of piosoning the whole river ? .
I spose untill they let/try letting all of us trap them in numbers then the jury is out on that one but one point i hadn`t thought about it before is if someone then takes a trap from say the kennet and then places in a waterway unaware of no signals being present there possability of transfer of virus/bacteria that wipes out our natives .....unlikely i know but there none the less .
We will never learn here eh Mink/Crayfish/Grey Squirell/Dutch Elm/Muntjack....Australia has learnt but only after our cock ups there Rabbits/Blackberrys/Carp and esp Fox`s.....Let the Gennie out of the box and all that .
Mind you the Ausies dont moan to much about Trout and Redys [our Perch ] cant think why Laughing Steve.

fair play fella
it's another mare of a problem, but until some supa dupa, putta genie back in the bottle appears, we gotta do the basics ourselves
if someone is concerned enough to try to assist, then once educated, they can crack on, and should be supported

unless we put down our rods for an hour a week, all we'll get is more of the same

Hi chaps with regards to catching and removing crayfish from the Thames, can anyone do this if so how can it be done without upsetting the balance of the river systems? As I fish for barbel more than anything, I find that my hook-bait is under attack more and more these days without any bite indication so I know it cant be some wily old barbel doing this. Do the EA have their own pots or do they rely on us?
