Invasive Asian Clam Species Found in Lake George

A team of researchers has discovered an invasive species of Asian clams in Lake George, which pose a large threat to the established ecosystem, and the delicate balance within.

The finding was made by experts of the Rensselaer Polytechnic Institute (RPI) Darrin Fresh Water Institute (DFWI). Students Jeremy Farrell was the first to identify the clam species.

The marine species was first identified last week, but experts have already established the invader to be Corbicula fluminea, a clam that generally lives in waters off South East Asia.

According to DFWI director Sandra Nierzwicki-Bauer, the invaders could potentially decimate existing populations of native mussels already living in the Lake.

The thing about the Asian clams is that they are capable of self-fertilization, a trait that allows them to achieving densities of thousands per square meter, essentially suffocating everything else around.

“It is imperative that we move quickly to determine the extent of this infestation to assess the best treatment options that can be undertaken immediately, We have reached out to the regulatory agencies to assess all our options,” explains Nierzwicki-Bauer, who is also a RPI professor of biology.

“It is now most important that we pull together with other organizations and the public to mount a rapid and effective response to this disturbing discovery,” explains Bruce E. Young.

“The community should be reassured that steps are under way to assess the extent of the Asian clam colony and if possible, eradicate it,” adds the scientist, who is also the chairman of the Lake George Park Commission.

“While the discovery of an established Asian clam population in the lake was not good news to hear, the good news is that all the groups involved are taking swift action and rallying the troops,” adds the executive director of the Lake George Association, Walt Lender.

He explains how various associations are dividing up the tasks that need completion before the invading clam can be eradicated from the lake.

One of the most important things to do is to get the word out that the clam species is present in the lake. People need to know this so that they can avoid spreading the organism unintentionally.

“We will be providing educational materials about the Asian clam and its spread to boaters, businesses, and residents all around the lake in the next few days,” adds Walt Lender.

Experts underline the need for swift action, given that a single clam of this species can produce up to 400 offspring each single day, depending on the conditions in the water.
