Abstract

We evaluated the prevalence of partial migration coexisting resident and migratory life history types within six white perch Morone americana populations in subestuaries Upper Bay and Potomac Choptank Nanticoke James and York Rivers of the Chesapeake Bay Otolith stable isotope δ18O values were used to resolve fish habitat use along an estuarine salinity gradient and define resident or migratory behavior The majority of adults within Upper Bay and Potomac River populations were resident whereas individuals from the Choptank Nanticoke James and York Rivers were predominantly migratory Beyond population differences large interannual variability in life history types was observed likely due to differences in estuarine conditions that influence growth rate of individuals eg temperature zooplankton density Because we observed partial migration in all study populations we suggest that this trait is characteristic of this species permitting plastic responses to variation in the estuarine environmentWe thank Eric Durrell and the Maryland Department of Natural Resources and Hank Brooks and the Virginia Institute of Marine Science for their help in obtaining fish samples We acknowledge Chris Eastoe and David Dettman University of Arizona Isotope Geochemistry Laboratory for their technical assistance We thank Rebecca Wingate Ryan Woodland Deanna McQuarrie Kari Fenske and Lisa Guy for their assistance in aspects of this research We also acknowledge the thoughtful review of our work by Karin Limburg and another reviewer This work was supported by the National Science Foundation under grant no OCE032485 Additional support was provided by the Massachusetts Marine Fisheries Institute This is contribution no 4546 of the University of Maryland Center for Environmental Science Chesapeake Biological Laboratory
