Comments | From the Rare Freshwater Mussel Survey, Rogers Lake, Lyme and Old Lyme, CT, SWCA Project No. 48737 report:
Asian clams (Corbicula sp) were observed in the portion of Survey Area 1 associated with the public beach. . . . A total of 7 individuals were found in two quadrates near the beach area. . . Numerous corbicula shells were observed scattered through the in-water portion of the public beach area. Neither live Corbicula nor shells were observed elsewhere in the lake. Asian clams appear limited to a small portion of the lake around the public beach and it may be possible to greatly reduce or eradicate this species from the lake. It is our understanding that the only method currently being used to control Asian clams is collecting them by hand.
In survey area 1 of 2021 mussel study - located near the public beach. |
