Mysis Shrimp Project Review

Researchers at the University of California, Davis Tahoe Environmental Research Center (TERC) believe Lake Tahoe’s water clarity can be positively influenced by native zooplankton populations. Observed clarity improvements coincident with a decline in non-native Mysis populations and a rebounding of native zooplankton in Emerald Bay led the group optimize a strategy for restoring Lake Tahoe’s clarity by reducing the abundance of Mysis shrimp. Monitoring in Emerald Bay performed by TERC suggests the high grazing rates of native zooplankton could improve clarity and the removal of Mysis would allow recovery of native zooplankton while improving both clarity and the overall ecological health at Lake Tahoe.
