... Therefore this section addresses zooplankton as a key element of the food web throughout the estuary, while focusing on details in delta smelt habitat, particularly brackish water (the "low-salinity zone") , during summer and fall.

... . The introduction and subsequent spread of the overbite clam in 1987 caused an immense disruption of the food web in brackish to saline waters between San Pablo Bay and the west-central delta, and several zooplankton species declined sharply (Kimmerer et al.

From page 233...
... In areas of higher salinity including San Pablo and San Francisco bays, zooplankton appear to be more abundant than in low salinity, but still less so than in many other estuaries. One component of the zooplankton that has only recently been examined is microzooplankton such as ciliate protozoa.

From page 234...
... First, most of the sampling by the zooplankton monitoring program has focused on the delta and Suisun Bay, with limited sampling in San Pablo Bay and none in San Francisco Bay. Because zooplankton move with the water, during high freshwater flows their populations move seaward, and the monitoring misses the bulk of these populations.
