In a new study, scientists created a top 10 list of the worst invasive species in the Great Lakes. The team of scientists from Michigan Sea Grant, the National Oceanic and Atmospheric ...
The zebra mussel (Dreissena polymorpha) is a small freshwater mussel, an aquatic bivalve mollusk in the family Dreissenidae.The species originates from the lakes of southern Russia and Ukraine, [3] but has been accidentally introduced to numerous other areas and has become an invasive species in many countries worldwide.
In 2008, the threat of quagga mussels being introduced at Lake Casitas and Westlake Lake in California from recreational boating resulted in the lakes' banning the use of outside boats. [22] As of March 2008, other lakes such as Castaic and Lake Cachuma are considering similar bans. In June 2008, the mussels were confirmed in Lake Granby, Colorado.
Aquatic invasive species were first introduced to the Great Lakes in the early 1800s through ballast tank water. [3] Freight ships carrying goods from foreign countries would travel through the Great Lakes and release their ballast water into the lakes. Ballast water tanks transport an estimated 7,000 aquatic organisms per day. [4]
State officials encourage residents to report potential sightings of invasive carp in the Great Lakes to the DNR. Reports can be submitted online at the DNR's website or to the DNR's fisheries ...
Wildlife officials across the Great Lakes are looking for spies to take on an almost impossible mission: stop the spread of invasive carp. Over the last five years, agencies such as the U.S. Fish ...
The Great Lakes have been impaired by invasive species such as the sea lamprey, zebra mussel, quagga mussel, alewife, round goby, and Eurasian milfoil. Asian carp are a threat to enter the Great Lakes. [16] The opening of the Welland Canal allowed the sea lamprey and alewife to bypass the natural barrier of Niagara Falls. Quagga, zebra mussels ...
In general, invasive species can potentially do great damage to local environments and native species. Ecosystems across the United States, such as the San Francisco Bay, Chesapeake Bay, the Great Lakes, Hawaii, and Florida inland waters, are now host to a wide number of non-indigenous species, 15 percent of which cause serious harm.
