Natural and human limitations to Asian clam distribution and recolonization—factors that impact the management and control in Lake Tahoe
Final Report [pdf]
Please contact Dr. Sudeep Chandra with questions regarding the reports.
The invasive Asian clam (Corbicula fluminea) is established and shows signs of spreading in Lake Tahoe. In 2002, low density populations (2‐20 individuals per m2) were observed in the south eastern portion of the lake, and in 2009 densities up to 5000 individuals per m2 have been measured. Through extensive field collection and laboratory experimentation, the University of California-Davis (UCD) and University of Nevada-Reno (UNR) science teams have found that this expanding population comprises the majority of benthic community biomass in regions where it has established, is associated with filamentous algal blooms, and (through shell deposition) has negatively impacted the aesthetic value of the Lake Tahoe nearshore.
In response to this nearshore invasion, federal and state agencies collaborated with UCD and UNR to develop a short term Asian clam management plan and implement a series of studies to understand the distribution, life history and reproductive strategies of this species in relation to population control.
The major objectives of this research were to:
