It might be that after 72 hours which we've found has been successful in the bay, that we don't find them in these places, but we are still going to continue to monitor in the future.\"\u003cbr/\u003e18. Close up shrimp in dish\u003cbr/\u003e19. Zoom into computer screen showing shrimp\u003cbr/\u003eThe U.K. Environment Agency is using cat food to try to catch a killer shrimp that is invading waters across the country. \u003cbr/\u003eFishermen are being warned to look out for the shrimp and new specially-designed traps are being trialled in the ongoing battle to stop the killer from spreading. \u003cbr/\u003eMeasuring the size of a fingernail they look innocent enough.\u003cbr/\u003eBut these are dikerogammarus villosus shrimps. \u003cbr/\u003eDubbed the \"killer shrimp\" because of their almost insatiable appetite, they are threatening to devastate Britain's native shrimp population. \u003cbr/\u003eThey also pose a threat to native wildlife such as damselflies and water boatmen, with knock-on effects on other animals that feed from them. \u003cbr/\u003eThe shrimp has now been found at three sites across the UK having made its way on the hulls of boats from eastern Europe via arteries such as the Danube and Rhine Canal. \u003cbr/\u003e\"The Dikerogammarus (villosus), this so called killer shrimp, is one of a group of invasive species that is coming out of the Caspian and Black Sea regions.  From the late 1990s onwards it's expanded progressively through the low countries, through France, and late last year it was discovered in what now turns out to be three locations in different parts of the United Kingdom - two of which are here in Wales, Eglwys Nunydd Reservoir and this lake behind me at Cardiff Bay,\" explains Professor Steve Ormerod from the Cardiff School of Bio Sciences. \u003cbr/\u003eThe predator thrives on hard surfaces like boulders, rocks and gravel just below the water surface where it kills its prey. \u003cbr/\u003eThey also attack insect larvae and baby fish, upsetting the food chain and threatening fish stocks further up the food chain. \u003cbr/\u003eHere in Cardiff Bay the threat is considered so serious that the Welsh Government and the Environment Agency, have joined a national task force to try to tackle the problem.\u003cbr/\u003e\"Our priority at the moment, is two fold again, to understand the extent of the outbreak across Wales, and England, but really is to prevent further inadvertent spread of the species to other water bodies. That is so important to us because of the potential for impact on ecology and biodiversity of those water-bodies,\" says the Environment Agency's  Andrew Johnson. \u003cbr/\u003eSpecial traps are now being tested by scientists in an attempt to establish the true extent of the problem. \u003cbr/\u003eBased on traditional cray-fish traps, they are assembled in a laboratory and baited with cat food - a delicacy the shrimps have apparently developed a taste for. \u003cbr/\u003eThey are then taken by one of the survey boats out into Cardiff Bay. \u003cbr/\u003eThey are left in the water for up to 72 hours to see how many of the invasive shrimps are caught in the fine mesh. \u003cbr/\u003eThe research helps the task force develop new policies to try to reduce the risk of the shrimp spreading, but it is water users and anglers that are being urged to do more to observe existing bio-diversity controls when moving between locations.\u003cbr/\u003e\"Since 2004, when zebra mussels were first discovered in Cardiff Bay we put into place bio-security measures, which is basically to do everything that is possible to ensure the boats, anglers etc, when they move between lakes or rivers from here don't take the species with them. And that is primarily to wash all their kit down as much as they can and to let it dry out thoroughly before it goes anywhere else,\" says David Hall, an environment officer for Cardiff Harbour Authority. \u003cbr/\u003eFor the scientists at the Environment Agency laboratories the main task now is to assess the effectiveness of the new traps before extending monitoring to other lakes and waterways.\u003cbr/\u003e\"We know they're in Cardiff Bay, and the we're going to go and deploy them in various other water bodies in South Wales that are high priority, that we've identified as high priority, and then we will see if they work. It might be that after 72 hours which we've found has been successful in the bay, that we don't find them in these places, but we are still going to continue to monitor in the future,\" says Environment Agency monitoring officer, Andrew Gott. \u003cbr/\u003eThere are concerns that the killer shrimp could already be heading for the waters of neighbouring Ireland. \u003cbr/\u003eBut for now scientists say they're not giving up the battle to contain it.\u003cbr/\u003e\u003c/span\u003e\n\u003c/div\u003e\n\u003cdiv class='action-container flex justify-between'\u003e\n\u003cbutton
