Officials issue warning after making disturbing discovery in US lake: ‘Infested’
Authorities in Minnesota, St. Paul made the alarming discovery of zebra mussel larvae, one of the most common threats to the waters of the Great Lakes region, in a lake outside Minnesota.
What’s going on?
Minnesota Department of Natural Resources (MDNR) officials, Minn. He confirmed the presence of zebra mussel larvae in Tanners Lake in Landfall. Pioneer Press. The samples showed 12 zebra mussel larvae, called veliger, found in the water.
“Although the DNR did not find adult zebra mussels in Tanners Lake, the presence of veligers indicates that zebra mussel populations are thriving,” officials said. he said in a statement. Because of their presence, Tanners Lake is now listed as “zebra mussel infested,” according to the department.
Minnesota state law requires boaters, fishermen and those who own waterfront property to follow strict rules to prevent the spread of zebra mussels, regardless of whether the lake is infested.
Why are zebra mussels important?
Zebra mussels are an invasive species that can spread rapidly. MDNR states that females can produce 100,000 to 500,000 eggs per year. After their veligers (fertilized eggs) form a shell, they can attach to surfaces and form dense beds that can reach tens of thousands in a single square meter. They were first recorded in the Great Lakes region in 1988 and are believed to be transmitted through cargo ship ballast water.
Zebra mussels have caused major disruptions to the ecosystem by outpacing native mussels and other species for resources and interfering with the growth of native aquatic plants. For humans, it can clog water intakes to power plants, coat boats and other equipment, and cut swimmers’ and pets’ feet when tied to docks and rafts.
Minnesota isn’t the only state dealing with headaches caused by invasive species. Officials in Iowa recently discovered zebra mussels in the Des Moines River; this was part of the westward expansion of mussels over the last few decades.
What is being done about zebra mussels?
MDNR encourages people to report the presence of zebra mussels in any body of water, regardless of whether there is a known infestation. They must also follow the ministry’s guidelines for cleaning boats, properly disposing of bait and drying containers for 21 days before moving from one body of water to another.
