According to the Department for the Environment, Food and Rural Affairs (DEFRA), non-native invasive species can prey on, compete with and displace native wildlife. The can spread disease and block waterways. They can completely alter the balance of ecology in a water system.
Fish populations can alter, and they can block up waterways which mean boat users have to take different routes. The financial costs can run into millions of pounds.
It is the first time this relative of the 'Killer Shrimp' has been found in the UK. David Throup, Environment Manager for the Environment Agency said:
“We are concerned that this invasive species has been found in the Midlands. We now have a dedicated team whose focus is to establish the degree of the problem, and whether the shrimp has spread wider than the locations already found. We are treating this as a priority so that we can come up with a plan to help contain it’s spread as far as possible.”
A species of shrimp related to the so-called 'Killer Shrimp' has been found on the River Severn near Worcester and on two canals in Worcestershire. The 'Killer Shrimp' is known to kill a range of native species, including young fish, and can significantly alter ecosystems.
A shrimp (Dikerogammarus haemobaphes), which is a relative of the so-called 'killer shrimp' has been found on the River Severn at Tewkesbury and Bevere near Worcester and on two canals in Worcestershire. It is the first time it has been found in this country.
According to the Department for the Environment, Food and Rural Affairs (Defra) the ) is "a voracious predator [which] kills a range of native species, including young fish, and can significantly alter ecosystems".
But the Environment Agency is unsure what the impact of this new species will be. They say until they have further information it will be treated as a "high impact species" and have a team working to establish how far the shrimp has spread along the river.
