San Francisco Bay and Estuary is largely urbanized and developed, and the southern bay is the most urbanized with many sources of nutrients, many concerns that the system might become eutrophic, and many questions about how South Bay has maintained its relatively good health. The hypotheses for why South Bay is not eutrophic, where other bays have not been so fortunate, include high bivalve grazing that limits net phytoplankton growth and high turbidity which also limits the phytoplankton growth rate. Understanding the bivalve grazing rates in the south bay includes the necessity of understanding temporal and spatial distributions of bivalves. Despite the critical need to understand all controls on eutrophication,...

Phytoplankton is an important and limiting food source in the Sacramento-San Joaquin Delta and San Francisco Bay; the decline of phytoplankton biomass is one possible factor in the pelagic organism decline and specifically in the decline of the protected delta smelt. The bivalves Corbicula fluminea and Potamocorbula amurensis (hereafter Corbicula and Potamocorbula, respectively) have been shown to control phytoplankton biomass in several locations throughout the system, and their distribution and population dynamics are therefore of great interest. As one element of the California Department of Water Resources (DWR) and the U.S. Bureau of Reclamation’s (BOR) Environmental Monitoring Program (EMP), the Generalized...
