Invasive mussels attached to the bottom of the boat were noticed in California. An unlucky unit could pose a big threat to the lake ecosystem, after which it was to swim. There is quarantine on many California waters – this is to limit the spread of a burdensome mollusc.
According to the water agency Solano, last week a new Łódź came to one of the marina serving the California Berryess Lake. While introducing it to the port, the marina's employees noticed that dozens of tiny mussels were attached to the bottom of the unit.
Quarantine before sailing
As it turned out, molluscs belonged to the species Limnoperna Fortunei. This strongly invasive species comes from China, and has been spreading in North America for several decades. For this reason, a quarantine program is introduced on many lakes (including Berryssa), prohibiting flowing on their water by boats, which have not been thoroughly cleaned and checked for the presence of invertebrates.
Although, according to the owner, the unit was previously cleansed, local services forbade it to use it on Lake Berrysea until an additional quarantine and inspection passed.
Not the only case
A similar situation occurred on Lake Folsom, which was also covered by the quarantine program. Officials reported that living mussels were found on the bottom of the boat brought to the Fols for the purpose of inspection. The decision was made to clean it and quarantine before again.
The Solano Water Agency has reported that the mussels L. Fortunei They pose a great threat to lake ecosystems. They can completely change the species composition of a given reservoir, promote toxic algae blocks, damage the boats, and also grow up and block water supply infrastructure.
