Hunt for 'killer' shrimp first found in Cambridgeshire

The hunt is on for a shrimp, dubbed "killer" because of its appetite, which is threatening river wildlife.

Traps baited with cat food and fish food are being used to detect the dikerogammarus villosus shrimp, the Environment Agency said.

The shrimp first found in Cambridgeshire can grow to 1.2in (3cm), much bigger than native shrimps.

Scientists aim to ensure no populations go undetected so more than 100 traps are to be set in "high priority" sites.

The Dikerogammarus villosus shrimp, which has gained the nickname "killer" as a result of its voracious appetite, has spread rapidly through Europe in recent years from the Black and Caspian seas.

It was first discovered in England at Grafham Water near Huntingdon last autumn.
Threat wildlife

Within weeks it had also turned up at Cardiff Bay and Eglwys Nunydd reservoir in Port Talbot.

The species preys on native wildlife such as damselflies and water boatmen and poses an indirect threat to other animals which feed on them.

Strict measures requiring boaters and anglers to thoroughly clean and dry all equipment before and after use were immediately put into place at the three sites where the shrimp has been found.

Paul Raven, heading a task force tracking down the invader, said: "This shrimp may be small but it poses a big threat to native wildlife in our rivers, lakes and streams.

"Native freshwater shrimps, damselflies and water boatmen could be particularly at risk, with knock-on effects on the species which feed on them.

"Since the first discovery at Grafham, our focus has been on containing it through effective biosecurity measures and investigating how far it might have spread.

"Extensive monitoring of rivers, reservoirs and lakes has not uncovered any new colonies but trapping will now be used to help ensure no invasive shrimp populations go undetected."

What is it about all these foreign things that keep coming over here and try and wipe out our much nicer things?

Crayfish, shrimp, squirrels, bees probably more too. There should be some sort of border control for nasties!

its more often than not irresponsible people releasing the nasties from their tanks into the rivers and or ponds - this is why you never flush dead fish etc from your tank down the loo.

IF you go on a fishing holiday abroad - dont use your own gear - hire it at the locale - cos you can import foreign beasties on your gear and release it here when you next go fishing.

If anyone is planning to release things in parliament - may i make a few suggestions?

Spitting cobra - black mamba, tigers, red back spiders....
