MADRID — Environmental experts warned all of Spain's waterways are at risk of being infected by the zebra mussel.
The National Commission for the Protection of Nature said the mussel was a 'national problem', reported the Spanish daily El Pais on Tuesday.
Dreissena polymorpha has been detected in Spain's biggest river, the Ebro, between Burgos and Vitoria, along with other rivers.
The Commission agreed to draw up an action plan to tackle the effects of the outbreak.
The mussel, originally from Russia, drinks large amount of water and removes most of the food for microscopic zooplankton and filter feeders.
Measuring little more than two to three centimetres in length, it can starve birds and fish which depend on this zooplankton to survive.
