ratory (National Marine Fisheries Service) and the Biol- 

 ogy Laboratory of Carolina Power and Light Company for 

 providing space. David Colby made valuable contributions 

 to this research. I appreciate Jeff Isely's advice and help 

 in analyzing fish otoliths. I thank Ernie Aschenbach for 

 sorting samples and mounting otoliths. And lastly I thank 

 Mary L. Moser for help and support during all stages of 

 this work from field sampling to reading numerous manu- 

 script drafts.
