This project will determine the susceptibility of the Chesapeake Bay to the invasion of exotic species released daily in huge volumes of commercial ballast water. We propose: to determine the viability of life history stages of exotic species released into the bay from ballast tanks of cargo vessels; to measure the interactive influence of environmental salinity and temperature on the survivorship and growth of organisms collected from ballast water; to estimate the likelihood that exotic propagules, released into Chesapeake Bay can survive under the environmental conditions of the Bay at the time of deballasting; and to test whether introductions of non-native species are occurring at areas of high commercial maritime activity.
