Russian Zebra Mussel Invades British Waterways
The zebra mussel, Dreissena polymorpha, is a species of small freshwater shellfish from southern Russia. It arrived on our shores in the 1800s on the hulls of cargo ships. They attach themselves to the steel pipeline clogging the water inlet pipes The zebra mussel costs water companies thousands a year to remove from treatment plants. In the past traps were used but now it is hoped a new powder will kill them off
