Thus, SWH should not be viewed as a static location that is good or bad for young fish but should be viewed as a dynamic place where predator-prey interactions may have important effects on densities, population sizes, and individual growth rates of fishes and zooplankton. Although these studies focused on the deeper channels of Suisun Bay, much speculation arose on the importance of the interaction between shoal and channel habitats for enhancing retention and survival of organisms associated with the low salinity zone.
Slough provide a conduit for the input or export of organisms to Grizzly Bay.
A major task of the IEP is to determine the factors affecting fish populations of management concern in the Bay-Delta, so that the effects of water management activities can be assessed and then mitigated or avoided. Understanding the complex interactions of hydrodynamics, contaminants, and lower trophic levels is important in itself but the proposed study will increase the relevance of those results to state, federal, and private agencies and other stakeholders by providing connections to fish populations, a topic of great management interest. In brief, we will use 63 cm dia. Zooplankton will be sampled using concurrent pump or plankton tows following Kimmerer et al. Sampling frequency-We will conduct two sampling cruises, one during a spring and one during a neap tide.
