ABOUT THE ZEBRA MUSSEL
During the last two decades, researchers have developed
Zebra mussels (Dreissena polymorpha) and quagga (Dreissena bugensis) originate from the Caspian Sea, near northern Iran and Russia. In the eighteenth century, they migrated to Europe through trade routes by sticking to the hulls of large cargo ships.
These Eurasian mussels were also transported through the ballast water. When the ships of Iran and Russia made the routes to collect merchandise in Europe they had to balance the ships using the water of ballast. Once arrived at port the water would be extracted to allow to realize the load, releasing of this way, the larvae in European waters. Once established in Europe, it took more than a hundred years for the zebra mussels to migrate to America. One of the reasons for this stagnation in the expansion was that until the year 1900 solid ballast was used for transatlantic navigation.
Due to decreased eradication effort, and lack of information, zebra invasive mussels are not seen by the population as a problem. However, as long as the zebra mussel continues to expire it will continue to impact biodiversity as it has been doing for the past two decades.
Countries are connected by watersheds making the transfer of the zebra occur permanently.
If applied correctly the ecological methods and products that have already been developed could be used to combat and prevent invasion.
