Canandaigua, N.Y. — The zebra mussels that have called Canandaigua Lake home are being pushed out by a new invasive species — the quagga mussel.
Bruce Gilman, professor of environmental conservation and horticulture at Finger Lakes Community College, said the quagga mussels have probably been in the lake for a year or two, given their length of about two centimeters. At this point, Gilman suspects they make up the majority of the lake’s mussel population.
Not native to lake’s ecosystem, they may have been brought over on a boat, Gilman said.
“It’ll change the chemistry of the lake, and a lot of the relationships of the food web,” Gilman said.
